What is better than a vibrating plate or a vibrating leg
Vibratory plate: what is it for, what happens and how to choose
A vibrating plate, or, simply put, a rammer, has only one purpose. to compact bulk materials. But despite such a narrow focus of this tool, it is used in many areas of human activity. And first of all, this is construction, with its help they compact the soil at the construction site and crushed stone dumping. It is even used for laying paving slabs. here it is generally irreplaceable. In this article, together with the website stroisovety.org, we will deal with the varieties of this tool, thereby answering the question of how to choose it, and also consider the possibility of making a vibrating plate ourselves.

Four criteria for choosing a vibratory plate
As mentioned above, the most important indicator of such a technique is its weight. it is this that determines the types of work that it can handle. In this regard, there is even a special classification.
The next thing to pay attention to when choosing a rammer is vibration force. this indicator characterizes the degree of compaction. Naturally, the higher it is, the better the ramming is done. but there is a limit to everything. Sometimes, too much effort can have a negative impact. For example, when laying paving slabs, forces over 20 kN will have a detrimental effect. vibration will destroy the tile itself.
An important indicator is the size of the working surface of the plate itself. Here, things are exactly the opposite, if we compare them with vibration force. the smaller the plate, the better the rammer will compact the soil and various mixtures.

Naturally, there is a classification by the type of drive. we have already talked about it. Also, we have already talked about reversibility, which greatly facilitates the work with this tool. Among other things, when buying a vibrating plate, you should pay attention to the material of the working surface (cast iron is best), to the presence of transport wheels, to the presence of a soil wetting system (such machines are more efficient), to the folding handle and, most importantly, to the integrity of the plate body and soles. The presence of bolts makes the tool less reliable.
Vibratory plate: varieties and their features
By and large, all modern rammers are arranged in the same way and practically do not differ from each other. the only differences that can be observed are in the type of drive used for the operation of this tool, as well as in some design features. For example, in the presence of a reverse movement. we will figure it out for a start, but first you need to understand how this tool moves along the rammed plane. After all, you do not think that such a heavy tool is moved by the operator manually. so the builder will not last long. The operator only directs the vibratory plate, and it moves due to fine vibration, thanks to which the ramming process is also carried out. the plate, as it were, pushes itself in the right direction.
But back to our reverse. it is convenient because the vibratory plate does not have to be turned during operation. It is dragged back and forth, switching modes of operation. they change the direction of the vibration, thanks to which it moves either forward or backward.
In addition to reverse, as mentioned above, vibratory plates can differ in the type of drive. in this regard, they can be divided into three groups.

There is also a third indicator (or rather a characteristic) of this instrument. mass. On this basis, all produced plate compactors can be divided into four groups.
Mass can be called almost the most important characteristic of a vibrating plate. its capabilities completely depend on it and on the size of the ramming platform. We will talk about this further, having studied the question of how to choose a rammer?

Do-it-yourself vibrating plate: how and from what to make it
If you set a goal, then you can make almost anything with your own hands, and the vibrating plate is no exception in this regard. To assemble it, you need only two things: an electric vibration motor of the IV-99V type and a bunch of iron with attached electric welding, a grinder and other similar tools. The most difficult to make a vibrating plate body, but even this will not be a problem for motivated people. The sole is made of sheet metal with a thickness of about 5 mm or more. its edges will need to be bent, so it is better to use a thinner iron, folding it in half. On this sole, an attachment for the vibration motor should be provided.
The second part of this machine is nothing more than a handle with which it will have to be controlled. It is not difficult to make it by welding, but there is one caveat here. you will need to extinguish the engine vibrations transmitted to the handle. Otherwise, it will be almost impossible to work with such a tool. There may be a lot of solutions here, but the simplest will be the use of powerful springs. they are installed between the plate itself with the motor and the handle. They can be slipped directly onto the bolts that connect the two parts of the machine. It will not be superfluous to think over the folding handle system. if you plan to actively use your product, then it will need to be transported somehow. And with a long handle it is not very convenient to do.
Homemade vibrating plate photo
What else will need to be taken care of is the control of the vibration motor. in the standard version, an engine start button and a rheostat are placed on the handle of a homemade vibrating plate. The latter is needed to regulate the number of engine revolutions. as the people say, it will be a kind of gas pedal. Also, do not forget to provide a special connector for connecting an electrical cable.
Vibratory plate or vibratory rammer? What’s the Difference?
Replacement of terms with “folk” names of the instrument is a frequent occurrence. And what’s the difference, with the help of which the sand will be compacted. vibrating legs or rammer? The main thing is that it is rammed.
This attitude is practiced until it comes time to choose an instrument at the time of purchase. The consultant will help in choosing after a detailed inquiry, but if the buyer is sure that he wants a vibratory plate, when a vibratory rammer is needed for his work. Such a purchase can end up as a waste of nerves. It is better to first familiarize yourself with the functions that distinguish vibratory plates from vibratory rammers, and immediately make the right choice.
Vibratory plate: main characteristics, scope
The ramming takes place using a wide plate that compacts the soil due to vibration and its own considerable weight.
Suitable for compacting loose materials (sand, gravel):
- when performing road works;
- when preparing a site for tiles;
- before performing work on the creation of landscape design, sports grounds.
The vibrating plate is compact, mobile, which allows it to be used in house plots, in small parks, when laying communications, in trenches. wherever it is impossible or impractical to use large-sized equipment.
Why is Whole Body Vibration Important?
The choice of the size of the site depends on the area to be treated: the more square meters you need to tamp, the wider the site is used. When working in a space limited in width, where a conventional vibrating plate cannot turn around, the reversible plate is more convenient due to the possibility of movement in the opposite direction.
Vibration Power Plates WORTH IT (TRUTH About Vibration Plates)
The tamping depth directly depends on the weight of the equipment. When working manually, it is better to choose a model with a mass of 60-121 kg. soil compaction with such a tool will be 20-34 cm deep.A technique weighing 121-305 kg will provide a layer compaction up to 90 cm.
For vibrating plates, two types of power units are used:
- Gas engine;
- electric motor.
Models equipped with an electric motor differ from gasoline ones in smaller dimensions, greater mobility, and maneuverability. Gasoline is more economical in operation, more suitable when compaction of a large area is required. For premises, only an electric vibrating plate is used, gasoline is used in outdoor conditions.
The principle of operation of the vibrating plate
In vibrating plates, vibration is excited by an eccentric fixed on the plate. Equipment operation stages:
- Internal combustion engine (diesel, gasoline) drives the eccentric.
- The vibrational vibrations of the eccentric are transmitted to the plate.
- The slab, due to these vibrations, compacts the soil or other materials.
Reversible models allow compaction to start in the opposite direction without shutting down the engine.
Vibratory plate or vibratory rammer
The reliability and durability of building structures largely depends on the quality of work on the preparation of surfaces on which construction will be carried out, the degree of their compaction and reinforcement. Depending on the area of the site and other construction conditions, vibratory plates or vibratory rammers are used for preparatory measures.
In what cases it is effective to use vibrating plates?
On construction sites free from buildings and various structures, vibratory plates are usually used. equipment weighing 50-400 kg. It is used for compaction of soils, crushed stone, sand, woodchips, asphalt, crushed rocks, when laying paving slabs and other low-plastic piece materials.
The rammer consists of a metal plate and an engine, most often a gasoline engine. Usually the drive is located at the front of the plate compactor The design includes a water tank. Irrigation while compacting asphalt prevents it from sticking to the sole.
A vibrating plate is an indispensable tool for landscaping, preparing a foundation for a foundation, repairing a roadbed. Such equipment is an economical alternative to heavy construction equipment in small areas and in hard-to-reach places.
Which is better, a vibratory plate or a vibratory rammer
If the site on which construction activities will be carried out cannot be freed from unnecessary structures and create conditions for the operation of the vibrating plate, a vibratory rammer comes to the rescue. This technique, which is also called “vibrofoot”, consists of a motor located on the frame and a ramming sole, the area of which does not exceed 600 mm2. Engine. electric or internal combustion engine. The most common vibro legs weighing 80 kg.
The principle of operation of a vibratory rammer differs from the principle of operation of a vibratory plate. In this equipment, the energy of the motor is converted into pushing movements of the plate in relation to the base. The impact force of the vibratory rammer is significantly higher than that of the vibratory plate, but the impact area is less.
The vibratory rammer is not suitable for paving asphalt, ceramic tiles and other low-plastic piece coatings, compaction of soil with high m of clay. A vibratory plate is suitable for solving these technical problems.
Scopes of vibratory rammers, in which they show more effective results in comparison with vibratory plates:
- hard-to-reach places of trenches;
- sealing of cracks in concrete with bitumen;
- consolidation of bulk materials near walls and foundations;
- carrying out works along roadsides.
Vibrating plate what is it? Purpose, types, characteristics and selection
The ramming and compaction of bulk materials, various types of soil takes place using specialized equipment called a vibrating plate.
The unit has compact dimensions, which allows it to be easily transported from site to site, easy to operate, efficiently performs its functions and in some situations is simply irreplaceable.
It will be about what a vibrating plate is, what types of it exist, what is it for and how to choose an option suitable for specific tasks.
Operating time without refueling
The time of continuous operation of the vibrating plate is directly affected by the fuel consumption of the engine and the volume of the fuel tank.
The first parameter, as you know, is determined not only by the type of internal combustion engine, but also by the number of its strokes, as well as the working volume.
For this reason, the operating time without refueling each vibrating plate is individual.
Most models with a filled tank and full load are capable of operating for 2. 3 hours.
For vibration compaction plates, the general specifications are standardized by GOST 31552-2012, issued in August 2013.
Standard machines of this type are accompanied by normative documents, which indicate not only all the technical characteristics of the mechanism itself, but also the compaction depth for various types of materials.
Dimensions and weight
The size of the work plate and the total weight of the device determine the compaction depth for various materials.
So the mass of the vibrating plate starts at 60 kg, in larger variations its weight can exceed 150 kg.
For ease of transportation, the latter are equipped with a frame with a handle, for which you can hook a hook or slings, for example, a crane, thereby facilitating loading.
The slab itself is made in the form of a rectangle, the length of which is usually approximately 0.3. 0.5 m, and the width can fluctuate in the region of 0.4. 0.7 m.
Diesel
High performance due to all the advantages of the diesel engine, which is usually installed on the heaviest models.
These are the most expensive vibratory plates, therefore, they are mostly common among road services and construction companies.
.
In addition to classic self-propelled models with a folding handle for movement control, vibratory plates with remote control are produced, which allow the operator to be at a safe distance from the work site.
A road vibrating plate designed for compacting asphalt and bitumen mixtures necessarily comes with a tank into which water is poured. This is necessary so that the material does not stick to the base of the apparatus, which implies periodic wetting of this surface. There are models with automatic water supply, which greatly simplifies the workflow. Such an irrigation system is operated by turning a crane.
In addition to buying a factory vibration machine, its fully-fledged version can be made from a walk-behind tractor, or rather, based on its engine.
The simplest vibratory rammer for concrete can be assembled from a hammer drill, equipped with a nozzle with a flat rectangular or square base.
Travel speed
For effective soil compaction, it is necessary that the length of the base of the vibrating plate, its movement speed and vibration frequency are in balance.
In other words, if the frequency of the exciter is 90 Hz, the length of the base is 0.5 m, and each surface area requires an impact of 1500 shocks, then for three passes, a movement speed of about 5.4 m / min is required.
The depth of soil excavation decreases with an increase in the speed of movement of the vibrating plate, since with each extra meter of speed, the vibration effect on any part of the area is more and more limited.
As a result, a light plate at a speed of 10 m / min is capable of compacting up to 0.2 m of material thickness, and with an increase in speed to 30 m / min. only up to 0.1 m.
For mobile self-propelled vibratory plates, it was found that effective processing of areas occurs at a speed of 15. 20 m / min for heavy models, and 6. 12 m / min for light versions.
Engine type and power
Electric motors and internal combustion engines are installed on vibrating plates.
The first option is preferable for work in rooms where the absence of exhaust gases is required.
Naturally, the minus of electric models is dependence on an electricity source and a limited radius of work.
The power of the electric drive is extremely low compared to combustion engines.
Internal combustion engines include gasoline and diesel engines.
The first ones are considered the most demanded due to their ease of operation and the possibility of winter operation.
Modern gasoline vibrating plates are often equipped with popular engines such as Wacker, Robin and Honda. The power of these units is usually 3. 6 hp.
Diesels for such equipment are installed much less often, and more specifically, on models with a large weight.
Kipor, Lombardini and Hatz are considered popular here, with an average power of 11. 15 hp.
Hinged
They are usually used as attachments for excavators.
These are hydraulic vibrating plates, that is, powered by the standard hydraulics of construction equipment, have a swing motor, have a large tamper base and weigh more than 500 kg (more often under 1 ton).
Vibratory rammer or vibrating plate?
By the appearance of vibrating plates and vibratory rammers, one can understand that vibrating plates having a large base area are designed to work across areas: laying tiles, compaction of foundations or asphalt. Vibratory rammers have compact dimensions, small base size and vertical layout, therefore they are more often used for soil compaction in trenches or narrow places.
The appearance of the vibrating plate and vibratory rammer
This does not mean that the vibratory rammer cannot work on an area or that it ramps incorrectly, but due to the small size of the base, compaction of a large area will take longer than a vibratory plate.
Differences between vibrating plates and vibrating rammers in terms of parameters
The table shows for comparison the parameters of Masalta vibratory plates and vibratory rammers from the section rent of vibratory rammers. Unlike vibratory plates with a wide range of parameters depending on the model and purpose, vibratory rammers have approximately the same weight, base size, impact force and compaction depth. This is due to the fact that when working with a vibratory rammer, the load on the operator is greater, he must hold and direct the vibro-leg.
On what soils are vibratory plates and vibratory rammers used??
In addition to dimensions, there is another important difference between vibratory plates and vibratory rammers: vibratory plates are not used on cohesive soils. Vibratory plates are excellent for compacting loose soils: sand and gravel. In clay, sandy loam or loam, the soil sticks to the base and the vibrating plate, instead of moving forward, buries itself in the soil. Vibratory rammer with small footprint and great operator control stays on the surface and compacts clay well.

VIBRATORAMMER: PRINCIPLE OF OPERATION, SCOPE OF APPLICATION
The principle of operation of the device is simple. Under the influence of oscillatory movements, the maximum compaction of soil or sand particles occurs, voids are filled. And although the unit has the same principle of operation with a vibrating plate, the unit achieves a greater degree of efficiency due to a smaller contact area. However, each of the units has its own pros and cons.
The vibro-leg is used for narrow and difficult-to-pass places, with a limited area:
– arrangement of columns and supports, compaction of trenches, holes for laying cables and utilities, for local repair of road holes;
– road services use a pipe-laying tool;
– the soil around drainage wells tends to sag, for such areas the vibro-leg is the optimal unit.
Light vehicles are multifunctional, because, given its modest dimensions, builders can tamp rubble near walls, equip bicycle or sidewalk paths, repair tram tracks.
During unexpected failures of pipeline networks, a tool is required to help re-compact the soil after repairs in a small area.
When repairing road surfaces, the compaction of bitumen in cracks is also carried out using compact technology. That is, the units are relevant where the area for laying the base is only a few square meters and the use of massive equipment is not possible.
How to choose a vibratory rammer
Brief:
During construction work, the first step is to compact the soil or other bulk materials, as well as clay, concrete mix and many others that are used in the construction of a foundation or foundation. Poor laying of the first layer can lead to a sagging floor, a collapsed foundation and other very unpleasant consequences.

WHAT IS THE TASK
WHAT DEPENDS ON THE FREQUENCY OF VIBRATION?
The compaction strength depends on the vibration frequency, an important parameter when choosing a rammer. In this case, sand or crushed stone is laid at a low vibration level, for compaction of sand, clay, aggregates with a high vibration frequency are taken. In the frequency range from 175 to 300 Hz, there is an intensive contraction of the interparticle spaces, which increases the efficiency of the compaction. Machines with such characteristics are used for laying soil.
Gasoline compactors with a vibration frequency of 250 to 670 rpm and higher have a performance of 110 to 200m2 / h. With such a wealth of choice, the most picky buyer will find the necessary tool.
Diesel devices with a vibration frequency of about 700 rpm operate at a maximum speed of more than 15 m / min, and their productivity reaches 240 m2 / h.
The vibration frequency of electric devices ranges from 400 to 650 rpm, while they have a decent speed of over 12 m / min.
When compaction of wet mixtures, moisture moves from the bottom up, the lower the soil moisture, the higher the compaction efficiency. For wet soil it is recommended to use vibratory plates.

expert of the category: “Construction equipment”
Compared to a bulky road roller, a vibratory plate is a delicate and miniature tool, and has a huge power. It is able to compact the surface very deeply and efficiently, using its own gravity, impact force and vibration vibrations for this. It is not surprising that the vibratory plate is often preferred in road and construction works. Especially if you need to roll up a narrow, tight, complex configuration. Private developers are also delighted with road rammers, since both their cost and rent are several times cheaper than that of a road roller.
Thus, the task of every vibrating plate. compactly compact bulk materials (soil, sand, gravel) or hard (asphalt, tiles), which she does with great success. BUT! Only if the type of road slab is correct. After all, its capabilities and the result of compaction, although they depend on many factors, are mainly determined by one single element. engine.
I always say that whoever said the engine was one hundred percent right. the heart of technology. It is its design, reliability and endurance that determine the fate of a particular technical unit, including vibrating plates. Therefore, this article aims to give you information about paving slab motors, their varieties, advantages and disadvantages. After reading it, you will be able to make the right choice of a vibrating plate and give preference to one or another drive, electric or internal combustion engine.
Diesel options for road slabs. the most powerful equipment
Diesel vibratory plate has all of the above advantages of gasoline. In addition, it will give gasoline counterparts a hundred points ahead in terms of power. And, of course, they have no equal in severity either. The mass of a paving slab, powered by diesel fuel, can be a ton or even more. For example, the Wacker DPU 130. is another monster that without fear enters the competition with a road roller weighing 7 tons. This equipment is mainly used for industrial and professional purposes. On the market, of course, there are budget models with diesel engines, but they do not shine with technical characteristics and high-quality work during long-term operation. One of the most requested slabs in our country. these are Wacker, NTC and Scheppach. Where the range will allow you to choose a stove for absolutely any task.
Of the main advantages:
- maximum engine power;
- high motor resource;
- the greatest compaction depth and impact force, low maintenance.
- price (but only if we consider branded models);
- due to weight, not suitable for tamping paving slabs and similar materials.
Gasoline road slabs: what is their advantage
The gasoline vibrating plate is not limited in the choice of the place of work, its engine is autonomous, not tied to the network. The drive power is much higher. Impact performance and ramming depth have been reinforced. In many ways, the weight of the unit itself also works in the pluses.
If electric brothers, as a rule, are light (up to 75 kg of weight) or medium-heavy (90-140 kg), then there are different types among gasoline ones:
- Universal (weight from 75 to 90 kg). They are used for soil, patching on asphalt roads. They give a seal for a quarter of a meter.
- Medium severity. up to 140 kilograms. Good for gravel, soil, asphalt. In the latter case, models with water supply to the working area are especially relevant so that the hot resin does not stick to the sole;
- Heavy aggregates. weight 140 and up to half a ton. This is a very powerful road equipment, compacting asphalt and concrete 60 cm deep.
- Power, weight, impact force and great compaction depth;
- Autonomous work, high mobility;
- The functionality has been expanded. reverse motion possible.
- Complex and troublesome service.
- They are more expensive, fuel is also not cheap.
Conclusion: For large-scale road works, for working with asphalt and hard surfaces, for large construction sites, remote from the network, it makes no sense to think whether the vibrating plate is electric or gasoline. there is only one choice. Gas engine. If there is a choice of engine brand, give preference to Honda (the world’s best Japanese engine), Robin or Wacker.
Electric vibratory plates: pros and cons
Let’s consider the first option in detail, because it is the cheapest and easiest to use.
The electric vibrating plate is easy to start. simply plugged into the electrical network with a cable and plug. But this is its main inconvenience. need electricity supply. over, of high quality, without interruptions and power surges. The coolest electric tool in the area where it is not. useless thing. Maybe connect to a generator, but this will incur extra costs. And one more drawback. cable. It ties the device to an outlet and will not allow it to go further than the length of the cord. And it gets confused, interferes with work.
The disadvantages of the electric drive also include its low power. No matter how powerful the electric motor is, it is inferior to the gasoline one in its technical characteristics and gives a limitation in the force of impact, the depth of ramming, as well as in the duration of work, since it gets very hot and you need to take breaks. Power range of the electric drive for vibrating plates: from 250 W to 1.5 kW.
Electric cookers are lightweight and easy to operate. However, the small weight in comparison with gasoline (up to 300 kg) gives a shallower compaction depth. no more than 25-30 cm. This weight is good for paving slabs, sand, loose soil.
Another big drawback is the electric road slabs. lack of reverse.
The fact is that all vibrating plates are divided into 2 types:
- Reversible (move both forward and backward);
- Straight forward. only steadily forward.
The former are incomparably better, since you can roll the surface harder without turning, and it is also better to maneuver in narrow places. So, for such plates, a two-shaft unbalance (eccentric) is needed, and the electric motor will not pull it. power is not enough.
- Quiet, environmentally friendly work;
- Indoor use;
- Light weight, compact size;
- Low price, savings in operation;
- No need for technical inspection, refueling, oil change, filters, candles.
- Networked, limited mobility;
- Low power, which leads to a low impact force and shallow compaction depth;
- Irreversibility.
Conclusion: Electric vibrating plates are more economical and much easier to operate and maintain, but they do not give deep compaction, and on large areas and where there is no network, they are ineffective. The scope of their application. landscaping near the house, compacting bulk materials in small areas, rolling surfaces indoors.
How the vibrating plate works and how it works
Regardless of which drive is installed in the vibrating plate, its design features and operating principle remain the same.
The stove consists of:
- Solid midsole. The size of the work sole and its weight determine the quality, speed and depth of compaction. The larger and heavier the plate, the faster the work moves, the harder the surfaces can be compacted. This element is made of wear-resistant metals. As a rule, it is steel (sheets thicker than 8 mm) or cast iron, enriched with additives for strength and elasticity. Reliable manufacturers also add stiffeners to strengthen the slab. The edges of the platform are bent upward to provide a smooth passage on a free-flowing surface. If you need to beat the paving slabs, then a special gasket is put on the metal sole. rubber or polyurethane mat, it softens the impact and protects the tiles from scratches and cracks;
- Eccentric. vibration mechanism (shaft) with an offset center of gravity. It acts like a flywheel. moves the plate vertically and moves it horizontally. forward;
- Engine. All the main technical characteristics of the vibrating plate directly depend on this element. For it is he who creates the force, starts the centrifugal clutch and moves the eccentric to create vibration. The power and design of the engine determine the speed of movement, the force and frequency of impact, the duration of work, the depth of the beat, therefore its choice. the first step when buying a vibratory plate.
So, you have only three options for choosing a road slab by engine:
- Electric vibrating plate;
- Gasoline;
- Diesel.
Cordless Vibratory Plates: New on the Market
Talking about different drives for vibrating plates, one cannot fail to mention one more special type. battery vibrating plates. In fact, they are considered a subspecies of electrical devices as they run on an electric motor. However, the motor is powered not from the electric stationary network, but from the battery. Thus, the user gets rid of the boring electrical cable that ties it to the outlet and interferes with full-fledged work, and gets a lightweight and maneuverable vibration plate that works autonomously, without being tied, without emitting gasoline exhaust and strong noise. Vibratory plates equipped with batteries. while there are still novelties on the road construction machinery market. But, not without reason, battery devices are called the technology of the future. After all, they embody the main advantage of a gasoline stove (mobility and autonomy) and all the advantages of quiet, easy-to-use and easy-to-run electric vibrating plates. The development of this market sector is just beginning. But today you can choose for work one of the excellent quality paving slabs from the German manufacturer Wacker Neuson. He launched a new AP-e series with capacious batteries and an electric starter on sale in Ukraine. Impact force ranges from 18 to 25 kilonewtons for different models. An electric motor is responsible for stable operation, the power of which can be selected from 1.2 kW to 2.2 kW. The motor is powered by a new generation lithium-ion battery. Its capacity and voltage allow it to ram bulk materials (crushed stone, sand, soil) and hard surfaces (tiles, asphalt) for a whole hour on a single charge. This time is enough for small and medium sites. The most powerful plate has a speed of 21 meters per minute. It has an irrigation tank to prevent hot asphalt from sticking to the sole. There is also a volcanic rug. It locks onto the sole if you need to tamp paving slabs or paving stones so as not to scratch them.
Advantages of battery vibrating plates:
- There is no connection to the outlet, the wire is eliminated;
- Clean work, no carbon monoxide emissions;
- Reduced operating noise;
- The device is lightweight, easy to operate;
- Simple inclusion (the main thing is to remember about timely charging);
- No need to change oil, candles and refueling with expensive gasoline.
- High price, especially the battery itself. It often needs to be purchased separately;
- Low weight gives weak pressure, that is, low impact force;
- Low power.
Thus, battery compactors do a good job with deep compaction of bulk materials. They can also be used for asphalt pavements. These slabs are relevant in small and medium-sized areas. An excellent alternative to a gasoline stove, especially in closed areas where there is no stationary power supply.
Which vibratory plate is better. diesel or gasoline, depending on the volume and nature of the work. Diesel will be effective and will pay off if you work with it a lot, often and daily. The best manufacturers of diesel engines. Hatz, Kipor, Kohler.

When and what is better to choose for compaction work:
vibratory plates and vibratory rammers
Vibratory plate or vibratory rammer: when and which is better?
In modern construction, preparatory, finishing other types of work are performed in a strictly defined sequence. This is the only way to get a high-quality and reliable result. At the preparatory stage of construction, vibratory plates or vibratory rammers are often used. They are also used in cases where it is necessary to carry out communications, compact the soil under the foundation, lay pipes or roads, and in many other cases.
In construction, you always need to be ready for different volumes of work and very different terms of their implementation. The choice of construction equipment often decides whether the construction contractor will meet the deadline or not. For example, the speed and quality of compaction work directly affects the transition time to the next stage of construction. If we talk separately about compaction work, then in this case the builders have a choice: vibrating plates, or vibrating rammers.
To make the right choice, you must carefully study all the criteria for this construction equipment. The main indicators by which they should be compared are: the role of a person in the work process, the amount of work, the ability to work in difficult places.
- Scope of work. In this context, reversible vibratory plates certainly have an advantage. They are suitable for compaction work of any complexity. At the same time, vibratory rammers are used mainly for light and medium compaction work. The advantages of the vibrating feeder are the large working surface area and the control of the equipment by a person who can easily control and hold it.
- The role of a person in the process of work. A vibratory rammer, like a gasoline vibratory plate, needs constant refueling. In cases of work with both types of sealing equipment, the role of a person in the process of work is very great. He is directly involved in the work of the mechanisms. The vibratory rammer is designed so that only manual control is provided. In contrast to it, the vibrating plate requires minimal human participation, whose role is reduced to control over the equipment. There are vibratory plates with hydraulic or remote control. For vibratory rammers, such a configuration is simply not acceptable. As a result, the broad capabilities of vibratory rammers are opposed by low weight, manual control and the ability to work in confined spaces.
- Working in tight spaces. In such cases, vibro-legs are certainly used. They take up less space than vibratory plates, and the result is no worse in the end. The vibratory rammer does not require a lot of space, so it is not necessary to free up a large space for it on the construction site, but you can immediately start working.
The Estate Project company offers its customers a wide range of sealing equipment: both vibrating plates and vibratory rammers.

In the life of every person, the question of choice is brewing several times a day. Whether it’s deciding what to cook for dinner, or what shirt to wear for work. Sometimes this choice does not mean much, but it also happens that the right decision can win a lot of time and material resources. In particular, here, we will consider which equipment for soil compaction is better to choose for different conditions.
Let’s start with a vibratory plate. This ramming machine consists of a metal plate with a width of 40 to 75 cm, which by vibration force ramps various types of soil. The engine that drives the vibrator is located at the front of the car, most often a gasoline engine. The most popular model is hondagx-160, hence the frequent name. honda gasoline vibrating plate. The reservoir, sometimes installed on the rammer, is used for sprinkling the asphalt with water. As a result, the outsole surface does not stick to the asphalt and effectively compacts it. Lightweight translational vibratory plates. up to 50kg are not recommended for use on asphalt, because their mass and engine power are not sufficient for efficient ramming of hot asphalt. From 100kg the vibratory plates will be reversible. When they work, you can start compaction in the opposite direction without stopping the engine.
For clarity, see what a 97kg vibratory plate looks like
Vibratory rammer or as it is also called vibro-legs are used for narrow places. Structurally, it is a gasoline or electric motor on a frame that drives a special mechanism. This system makes the rammer bounce up to 65mm and a steel pad located at the bottom of the rammer compacts sand or gravel. Because The surface area is less than in a gasoline vibrating plate, the force will be greater, which means that the compaction is effective. If vibratory plates are used to compact large areas, then the electric HCD vibratory rammer or its gasoline counterpart are used for cable laying, trenching, channeling and foundations development.
The most popular weight for a vibro-leg is 80 kg, while fuel consumption and efficiency are in an optimal ratio.
If it is still not clear, then watch the video about the vibratory rammer
Hence, we will draw the following conclusion: If compaction work must be carried out over a large area and at the same time good speed is required, then the best choice is a gasoline vibratory plate. If the work is mainly carried out in hard-to-reach places, then the optimal one is a vibratory rammer (vibro-leg).
