Vibratory plate with gasoline engine
Step-by-step assembly: a vibratory plate with their own hands using a gasoline or electric motor
Compacting soil, backfill or concrete castings during construction work requires special equipment. In private construction it is not uncommon to encounter problems with foundation deformations or settling.
The cause of these events is poor compaction of the sand fill layer. According to the technology, the density should correspond to the condition of the long-used country road. Checking the quality of compaction is usually done by walking on the compacted area. if no shoe impressions are left, the work is satisfactory.
Tamping soil is required not only on critical areas. The usual laying of tiles on garden paths requires the creation of a layer of sand cushion, which also requires a maximum degree of compaction, otherwise the coating will start to fail and move apart. It is impossible to achieve high quality of work by hand, so a vibratory plate comes to the rescue.
To buy a ready-made device for home use, not everyone can afford it, as the cheapest model will cost 20 thousand rubles. rubles. People who can handle a locksmith’s tool and a welding inverter prefer self-made vibratory plates, which saves the budget and brings the desired result.
Advantages of a homemade rammer
The main advantage of the vibratory plate, made by your own hands, is its low cost and the possibility of high-quality and effective performance of work. Simple design ensures reliability and durability of the mechanism. In addition, the homemade vibratory plate allows:
- safely perform tamping of any surfaces;
- to reduce the amount of manual labor in the performance of works;
- improve the quality of the bases of walkways and grounds;
- It is good for compacting dry cement or semi-dry concrete mixes when paving them.
Availability of mechanism for compaction of loose soils and bulk materials will allow you to perform any amount of work on landscaping and exterior design.
The main working element is the heavy metal platform, which can be made of gray ductile iron or steel. The vibration effect on it is transmitted from a mechanical vibrator, driven by a gasoline, diesel or electric motor.
To control the vibratory plate when moving it on the work site, there is a sturdy handle. Additional equipment may include a fuel tank or electric starting equipment. The engine and the vibrating device are mounted on a frame attached directly to the ramming platform.
Vibratory plates are used for a wide range of applications
The machine is used for repair and construction, paving roads and sidewalks, construction of various sites and other works. It is used as in industrial scale, as well as at home. The uniqueness of this mechanism in its relatively small size and ability to work in environments where cumbersome machines are not suitable. For example, laying a garden path or sidewalk in a private home. Asphalt, concrete, sand, regular lawn soil and gravel are compacted with the machine. Such a machine is indispensable for sidewalks and roads. Even in narrow pits and trenches it can be operated. The advantage of completing the mechanism is a reverse movement, it is much easier to work in a small area, where you often need to turn around or overcome obstacles.

Buying the unit
If you have decided to buy a machine, you need to consider both the basic criteria and minor nuances that will facilitate the work or increase its life. However, it is impossible not to mention the manufacturers of vibration rammer devices.
Special account equipment from european manufacturers. German technology is distinguished by its reliability and long life. Even the rolling models show good quality and pace of work. All equipment has double margin of safety. Wacker, Weber, Ammann, Bomag produce professional equipment.
Israeli Shatal and Czech NTC are less resourceful than Germans, but on construction sites and private estates are also good workers.
The South Korean Jeonil Minery is not inferior to Czech or Israeli products. On the Asian market, it is the best of all vibro machines.
Russian products from Splitstone, Motoprom and SPPO are inferior to average European samples in convenience and functionality. But modernization continues, and new, more perfect models appear on the market.
The Chinese, as usual, charge by price. Their products are only suitable for occasional light-duty work. TEKPACK, MASALTA, DYNAMIC, CIMAR stand out among the mass of unknown manufacturers.
How to make a gasoline vibratory plate with your own hands
In early spring, when the temperature rises above freezing, suburban and homestead plots begin to come to life. Some people are engaged in gardening and preparations for planting, and some people are busy with repairs or construction. As a rule, without the excavation work is not a thing: a path to tamp the tile, then in the ditch to strengthen the bottom. This is where a vibratory plate, made by your own hands and according to your own drawing, comes in hand.
What are vibratory plates for?
Such a mechanism is used for compacting loose soil and building materials, as well as non-consolidated surfaces of asphalt and concrete. It is especially effective on small territories and sidewalks, as well as in places where heavy machinery is inaccessible.
The use of this device will greatly facilitate manual labor in homestead or cottage landscape construction. Produce soil compaction on a garden path or a small parking lot near the house is easiest with a mechanized method.
The vibrodynamic rammer will also come in handy when excavating underground utilities, when you need to compact the soil at the bottom of the trench.
This device operates by vibrations generated by the rotation of the flywheel, attached to the eccentric:
- The displaced ballast via the drive transmits the vibration created to the iron base. the sole.
- The heavier it is, the stronger is the oscillation and tamping.
Similar device have a vibrating plates in factories for the manufacture of concrete products and vibrating lathe for cleaning various objects from burrs, scale and other defects.
The criteria for selecting the device
Several conditions affect the quality of work. In order to obtain an excellent result it is necessary to take into account all the properties of the model and choose the site rammer, focusing on the tasks facing the unit.
Characteristics by weight
This is the main quality of the vibrator for tamping any surface, which affects the performance of the task. This is something to look out for when buying or building a home-built vibratory plate. With their own hands assembled device is often skewed towards one feature, so it is necessary to understand all the characteristics of the mechanism.
The weight of the vibratory rammer devices is distributed in this way:
- Light models weighing up to 75 kilograms are suitable for work on surfaces with a small (up to 15 centimeters) layer of soil: paths in the garden, the lawn for laying tiles or mats.
- Medium with a thickness of up to 25 cm are fairly versatile. They are equally effective for light-duty jobs, for laying asphalt and paving slabs. Their weight is in the range of 75-90 kg.
- On the construction site when pouring foundations and strengthening the bottom of communication ditches, as well as laying several layers of asphalt pavement, medium-heavy vibratory machines weighing up to 140 kilograms and a compaction depth of up to 60 centimeters are useful.
- Heavy plates do the same work as the previous models and weigh more than 140 kg.
What a vibratory plate is made of
Before you begin to make a vibratory plate with your own hands, it is necessary to make a drawing of it. To do this, you need to know what parts make up the machine.
Any modern vibratory plate consists of several elements:
The working plate is mainly made of cast iron, and its characteristics are determined by the quality of this material.
Poor quality cast iron can crack when working with sand and gravel mixes.
These types of soil contain small stones, which in the process of tamping pinpoint the surface of the slab.
The size of the working surface is also important. When the plate has the right geometry, its surface is able to clean itself without leaving any residual soil on it.
The smaller will be the surface of the working plate, the better will be the compaction of the ground.
That’s why it’s better to make a smaller surface for your own hands when making a vibratory plate if it doesn’t reduce the vibratory properties.
The vibration unit is attached to the plate, so all connections and attachment units must be assembled particularly carefully.
All parts must be made of high quality and durable materials. High vibration index and a certain weight of the product sets the level of impact on the ground.
The seal of the vibration unit must prevent leakage of lubricating fluid, keep out dust and dirt, as well as withstand prolonged loads.
The vibratory plate is driven by an electric motor.
For better work quality in the vibrating machines an internal combustion engine is used, which has maximum power and performs tamping in all conditions.
What is a vibratory plate?
What you need a vibratory plate for
Inherent to construction work is the process of compacting various loose substrates. For example, crushed stone, sand, soil and other similar materials.
Basically these are preparatory phases for pouring concrete, asphalt, laying tile, or constructing a foundation.
In order to mechanize the tamping process the so-called vibratory plates are used. Their mechanism of action is quite simple.
The vibrating action of the equipment causes the small particles of the compacting layer to be brought as close together as possible, forces the excess air out and produces a smooth base of the required density at the finish line.
Buying a similar machine for yourself is rather unprofitable. Self-made vibratory plate is much more profitable.
Structure of the mechanism
The vibrator is mounted on a weighty platform, and a motor is installed above it. The last two components are connected by a coupling and a V-belt drive.
The rotational motions of the motor are converted into vibratory motions by a vibrator and transmitted to a heavy platform, which in turn impacts the tamping surface.
The reversing function of the device makes it possible to work in narrow trenches and pits.
The plate itself is made of steel or cast iron, preferably of good quality. Otherwise, the service life of the device is significantly reduced, and cracks appear on the surface of the base.
The size of the plate affects the pressure exerted by the mechanism on the rammed layer. The smaller plate compacts the ground better.
The density of the finishing layer depends on the vibrating force. The higher it is, the better the material is rammed.
Classification by power supply
Electric. The electric plate is considered the most economical. This is the one recommended to assemble with your own hands for your own farm.
All the more so that the technical characteristics of vibratory plates with an electric motor are not inferior to their competitors. The only disadvantage can be considered the condition of having an available power grid.
Gasoline. expensive than electric, but less expensive than diesel.
However, it is more profitable to buy fuel for diesel plates, although the motor itself is the most expensive of the three described.
The same disadvantage is its high noise level, reducing working comfort.
The power of the installed motor must be sufficient to work with a heavy plate. Otherwise the latter will be loaded with loose material.
Classification by weight
- Lightweight boards. Weighing 75 kg. For layer thickness up to 15 cm. Such plates are used for landscaping works, laying paving tiles, damping polyurethane mats.
- Universal plates. Their weight ranges from 75 to 90 kg. The maximum layer to be treated is 25 cm. They are used for landscaping, repair of road surfaces, including patching asphalt.
- Medium-heavy. Weight 90-140 kg. The thickness of layer to be treated up to 60 cm. Usage. laying of road pavement in layers, backfilling of trenches on the perimeter of the foundation.
Classification by direction of travel
According to the direction of movement during ramming, vibratory plates can be direct or reversible.
Straight plates can only go forward and have to be reversed if a second pass over the rammed layer is necessary. And that’s a waste of time, albeit small.
Reversible vibratory plates can go either forward or backward. They give you more performance. Plates weighing more than 100kg are usually equipped with reversing.
Additions to the package
If your vibratory plate is equipped with a sprinkler system, that’s an added bonus.
This protects the unit from sticking to the rammed surface. They must carefully protect the engine from water ingress.
So the small particles of bulk material won’t clog the mechanism, and the machine itself will last a lot longer.
Homemade vibratory plate
Factory-made tamping units cost a lot of money. This is why some craftsmen prefer to build a vibro-compactor by themselves. This process will require welding skills and a small set of tools.
