Gasoline Vibratory Plates
This is a fairly popular type of road repair device that is designed for autonomous operation and can be used far from communications. A significant disadvantage is the high level of noise produced. The technical design of the device is quite simple, but this does not reduce its functional efficiency.
The main advantage of a gasoline vibratory plate over an electric one is its complete autonomy, the ability to work in any conditions. The high degree of reliability of modern motors guarantees long-term operation of the installation.
Gasoline vibrating plates by type of work are divided into translational and reversible. The first version of the design allows you to move only forward, the reverse-type vibrating plates have a Forward-Backward switch. Simplicity of control and maneuverability of the devices make it possible to carry out compaction work in confined conditions. The unit in service does not require special qualifications and high costs.
Among the Russian models of gasoline vibrating plates, it is worth noting Energomash VP-88080, the cost of which is 42,650 rubles. The sample has a 4-stroke Honda GX-160 engine and a 3.6L fuel tank. For high-quality ramming, a 15-liter water supply tank is installed.
Among professional builders, the Atlas Copco LG160 reversible gasoline cooker model is popular. To work with paving slabs, it is possible to install a polyurethane lining that protects the material from damage. Price - 188 360 rubles.
Another professional model of the reversible plate compactor is the Wacker Neuson WPU 1550 Aw. The wetting system works only during the compaction process; at idle speed, a special valve is closed. The cost of the car is 101 250 rubles.
Additional elements
Additional elements are:
- handle (carrier) used to guide the vibrating plate during operation;
- a trolley on which the device is installed when moving from one place to another;
- a tensioning mechanism that ensures tight contact of the drive belt with the pulleys of the engine and vibration mechanism.
The handle is a long U-shaped bracket made of a tube. Its attachment to the plate is made through a swivel joint, which partially compensates for vibration and protects the worker from its effects.
The trolley is a separate item, although rigid mount options exist. It is brought under the stove, tilting the unit towards itself by the handle, supported on a trolley and transported to the desired place. With a rigid mount, the legs with wheels are installed on the base in an inverted position. If it is necessary to move the vibrating plate, the installation is turned over and taken to another place.
Tensioner ensures tight contact between drive belt and pulleys
It is important that the roller has a groove corresponding to the groove of the pulleys. This will help extend the life of the belt.
If the roller of the vibrating plate is installed from the outside, the size of the groove must correspond to the back of the belt. An adjusting screw is used for tensioning, allowing the belt to be loosened for replacement or tensioned to a working condition.
What are the vibratory plates?
The range of vibrating plates is classified according to the following main features:
- - device weight;
- - vibration force;
- - working surface area;
- - type and power of the engine.
The first three characteristics determine the quality of the seal. The force that must be applied to move the vibrating plate during operation depends on the power of the engine.The more powerful the motor is on the platform, the easier it is to walk on the surface.
The main parameter by which this mechanism is selected is its weight. There is a clear gradation here that should be considered in more detail.
Light vibrating plates (weight up to 75 kg)
They are used for landscaping (paths made of sand or fine gravel no more than 15 centimeters thick). To seal the paving slabs, they are equipped with damping polyurethane mats.
Universal (weight from 75 to 90 kg)
The most common type of site vibrators. Fields of application: landscaping, patching of asphalt pavement and its embedding after the laying of utilities.
Most often, the work of a vibrating plate of this class is carried out on a layer of sand, asphalt, crushed stone or gravel up to 25 cm thick.
Medium heavy (weight from 90 to 140 kg) and heavy (weight over 140 kg)
They are used for layer-by-layer compaction of the foundations of roads under construction, compaction of backfilling of trenches around foundations, as well as local repair of asphalt pavement.
They can work on sand, gravel, asphalt and gravel from 25 to 60 centimeters thick. For high-quality compaction of asphalt, the weight of such a mechanism should not exceed 100 kg.
Vibration Effort
This parameter seriously affects the degree of compaction. Therefore, choosing from two plates with the same weight, it is better to buy a device with a higher vibration force. For light vehicles, this parameter does not exceed 10 kN, so they are not suitable for compacting asphalt.
If you plan to compact paving slabs, remember that the vibration force of a machine weighing from 75 to 90 kg should not exceed 18-20 kN. With a higher value of this parameter, the platform will strongly press the tile into the base and can destroy it.
It is not difficult to determine the surface area of the vibrating plate: the smaller it is, the better the base will be compacted. Therefore, with the same vibration force, it is better to buy a stove of a smaller area.
The vibrating platforms offered on the market are equipped with three types of engines: electric, gasoline and diesel. For work on a personal site or a small construction site, an inexpensive electrical mechanism is optimal.
If autonomy and quality of compaction are in the first place, the best option would be a gasoline vibrating plate. Powerful units with a diesel engine are intended for professional use. They are reliable, durable and economical.
If the weight of the vibrating plate exceeds 100 kg, then it is rather difficult to unfold it for repeated passage in a narrow place. For such work, a reversible vibratory plate is used, which can move both in the forward and in the opposite direction.
For ease of transportation, these mechanisms are equipped with wheels, and to reduce the harmful effects of vibration on the hands - with a special energy-rinse handle. Asphalt compacting units are equipped with a water tank and a platform sole dampening system.
Having decided on the main technical characteristics of the vibrating plate, you need to choose a manufacturer that produces high-quality equipment. Reliable and economical Japanese vibratory plates Honda, as well as German Masalta, Wacker Neuson and Ammann enjoy high popularity today. Estimated prices for light gasoline vehicles (56-67 kg) are from 27 to 63 thousand rubles.
Final work
After assembling the slab, all metal parts must be primed and painted to protect against corrosion. Attach the lead-in cable securely to the control handle to prevent it from being run over. The engine switch must be located on the structure itself to allow an emergency stop during operation.
After that, a do-it-yourself vibrating plate must be tested. Freshly dug earth is best suited for this.Testing on bulk material will prevent full load testing.
As you can see, it is quite possible to make a vibration machine on your own. But for this it is necessary to have initial knowledge and experience of locksmith and welding works.
| Billet of parts for mounting the shaft. Two pieces of a square 10 cm long and two hub covers on metal plates are prepared. Then we press the bearings into these hub covers. | |
| Vibrating unit assembly. We assemble a vibrating unit from the prepared parts, in which bearings with a shaft threaded through them are fixed. A pulley is attached to the shaft from the end. | |

| Assembly of loops. Opposite the rings welded to the plate, we weld the counter rings to the frame, so that their location completely coincides. | |
| Assembling the entire assembly. We connect the prepared frame and the pivot plate with a hairpin through the hinges. Considering that the structure will vibrate, we insert the hairpin through the rubber bushings. | |
| Belt adjustment. In order to set the appropriate degree of belt tension, nuts are screwed onto the vertical stud on both sides of the plate through washers. | |
| Installation of racks under the frame. From each corner of the frame, a support 10 cm long is welded. Counter supports are cut out of 8 mm thick sheet steel, which will be attached to the sole of the vibrating plate. The connection of the supports will be carried out through rubber elastic cushions. | |
| Assembly of shock-absorbing supports. The prepared supports and strikers are bolted together through rubber cushions. | |
| Engine installation and vibration assembly fitting. | |
| Preparing the sole plate. We mark a sheet of steel 10 mm thick so that a rectangle of 40 × 120 cm is obtained. | |
| Trimming corners. At the corners of the prepared slab, measure 50 mm from each edge and connect the marks with a diagonal line to make a triangle with a right angle. | |
| Bending of the front and rear edges of the slab. From the front and back edges, 100 mm are measured, and at this distance a line is drawn parallel to the edge of the plate. | |
| Assembly of all elements. The previously assembled structure, including the mounting brackets and the motor frame, is welded onto the soleplate. At the same time, fold lines are welded along the front and rear edges of the sole fold. | |
| Assembly and installation of the handle. At the rear of the sole, loops are welded to which a handle is attached, welded in the shape of the letter "P" from a profile pipe. | |
| Connection and trial run. The power cable is connected to the motor through an RCD. The vibrator is connected to the network and a test run is performed. |
Vibratory plate design
The compacting effect on the soil surface is provided by the action of shock-type vibration. Structurally, the unit includes three main blocks, which can be seen in the photo of a gasoline vibrating plate:
- support plate;
- eccentric with vibration effect;
- Gas engine.
The eccentric is activated by the engine. Vibration occurs, as a result of which energy and vibrational action is transmitted through the sole of the tool to the surface to be compacted.
Vibration is transmitted to the substrate during construction work through the sole of the machine. For effective sealing, the plate must be sufficiently heavy and resistant to wear. It is recommended to select units with a working area that best suits the list of work performed on the construction site.
The working platform is made of cast iron or steel. If you plan to lay paving stones or tiles on sidewalks, then the sole should have a rubber or polyurethane mat. Rounded edges provide smooth movement, and stiffeners help reinforce the structure.
What to look for when choosing a vibratory plate or soil rammer
- Drive power is one of the main factors for comfortable operation.If this indicator is insufficient in relation to the weight of the plate, then during vibration the rammer will simply bury itself in the ground. This is especially noticeable when driving at an upward slope. If with light options the operator can still somehow influence the apparatus with the help of physical efforts, then during the operation of heavy samples this will not work. If the drive power is sufficient, the vibrating plate will move in the given direction by itself.
- The presence of a folding handle and wheels for transportation will greatly simplify the operation of the rammer. These elements are not required during operation, however, during transportation, they will certainly come in handy.
- The irrigation system is an additional function that can be not only useful, but necessary. So, during the compaction of asphalt, it is necessary to constantly irrigate the surface, otherwise the plate will simply stick to the material.
- The presence of protective covers and couplings allows to extend the service life of the device and reduces the likelihood of its failure. These elements protect the working parts from falling on them particles of the compacted soil.
- You should not chase a low price or a famous brand. In the first case, you will receive an unreliable device, and in the second, you will overpay. It is better to analyze the assortment and prices yourself, which can be found on the Yandex Market. And to find out more about the current recommended models, read our following articles.
Hope today's article was clear and helpful. In one of our next materials, we will tell you how to assemble a vibrating plate with your own hands, and of course, we will take a closer look at the most popular models offered on the Russian market.
Vibratory plate selection criteria
When the question arises before you: which vibrating plate to choose, first of all, you need to determine what you are going to do, what kind of soil will be, the expected volume of work, and also correctly calculate your physical and financial capabilities.
There is a clear distinction here:
- For arranging paths, landscaping, laying tiles and various types of rugs, it is optimal to choose a vibrating plate with a working weight of 75 kg;
- For paving asphalt, repairing roads and, in general, compacting soil up to 25 centimeters deep, choose a tool with a working weight of 75 kg;
- For work on the arrangement and repair of roads, compaction of trenches and work with a soil depth of 25 centimeters, a vibratory plate with a working weight of 90 kg is required.
The vibration force will depend on the degree of soil compaction. In this case, start from how strongly it is necessary to compact the soil, however, such parameters as the strength, area and mass of the vibrating plate must be combined, and therefore, consult with a specialist or seller.
Last: it is better to stop your choice on models from well-known manufacturers, which give appropriate guarantees and have already earned their reputation for many years of work.
Diesel Vibratory Plates
They have a principle of action similar to gasoline counterparts, differ in heavier weight and increased power of compaction of the road surface
For successful and long-term operation, it is important to monitor the quality of diesel fuel
Diesel vibratory plates have many advantages:
- power: the highest power among the large family of plate compactors. Diesel vibratory plate can replace a multi-ton roller;
- operation does not require special training;
- maintenance can be carried out directly at the workplace;
- has high performance;
- good compaction of various types of soils, coatings and bulk materials;
- an economical diesel engine allows you to operate the vibrating plate for a long time without refueling;
- the design makes it easy to load and transport the vibrating plate to another work site.
