Gasoline vibratory rammers: characteristics and selection

Gasoline vibratory rammer (vibro-leg) - equipment for compaction of soil under the foundation, asphalt and other road surface. With its help, paving slabs are laid for the improvement of pedestrian paths, driveways and park areas. The technique is widely used in the repair and construction sectors.

The petrol vibratory rammer is a versatile technique characterized by mobility, compact size and unpretentious maintenance. The device is equipped with a petrol 4-stroke engine with 1 or 2 cylinders. The design of the equipment provides for air cooling of the motor.

Let's list the main characteristics that affect the operation of equipment.

• Weight. The depth to which the soil and various bulk materials can be tamped directly depends on this parameter. For example, models are lightweight (up to 75 kg) - they compact soil up to 15 cm thick, universal - from 75 to 90 kg. Units with an average weight of 90-140 kg are designed for ramming materials to a depth of 35 cm.When large-scale works, powerful and heavy equipment up to 200 kg is used - it can be used to process soil with a layer of up to 50 cm.
• Impact force. The parameter affects the rate of the compressive force that the sole of the equipment exerts on the material being processed.
• Shoe dimensions. The size of the sole depends on the effort imposed on the treated area. The larger the size of the shoe, the less effort will be required to tamp a unit of area.

The important characteristics of the vibratory rammer include the type of stroke. By the type of movement, the technique is divided into reversible and non-reversible. In the first case, the equipment has the ability to reverse without turning. Such units are simpler to operate and maneuverable, but differ in weight and massiveness.

All rammer modifications have a similar design. It includes several main mechanisms:

• base plate (shoe);
• eccentric vibrator;
• engine.

The sole is the main working body of the device. For high-quality ramming, the shoe must have optimal weight and wear resistance. The working platform is made of cast iron or steel. The introduction of various additives into the alloy makes it possible to increase the resistance of the plate to mechanical loads, and to increase its wear resistance.

The vibrator includes an unbalanced shaft installed in special supports. Its principle of operation is similar to that of a flywheel. The design also includes a frame for attaching the motor and handles with which the operator controls the unit.

Gasoline vibratory rammers are easy to use, maneuverable and compact in comparison with electric or diesel units.Due to a weighty set of advantages, such equipment is in great demand.

Below are the most popular models of gasoline vibrating plates with an optimal ratio of build quality, cost and functionality.

• Champion PC1645RH. The device is Russian-Chinese production with a 4-stroke 9 hp engine. with. The technique is universal, since it has the ability to move forward and backward. Its advantages include quiet operation of the engine (Honda GX270), economical fuel consumption, convenient control.

• DDE VP160-HK (American design, assembled in China). Reverse equipment powered by 6 HP Honda GX200 engine. with. Allows to compact soil up to 50 cm deep in 1 pass. The equipment is reliable and durable due to the equipment of the vibrator rotor with reinforced bushings.

• Zitrek CNP 25-2. The rammer is Czech production. Equipped with Chinese Loncin 200F 6.5 HP engine. with. The unit provides direct and reversible movement. The equipment platform is made of durable cast iron. The model is distinguished by its budget, ease of management. The disadvantages include a small compaction depth - no more than 30 cm.

• Mikasa MVH-R60E. A small Japanese rammer weighing 69 kg. Equipped with a 4.5 liter Subaru EX13 engine. sec., maximum torque 8.1 Nm. It has a reverse function, is equipped with a built-in water tank, so the unit can be used when paving asphalt. The disadvantages of the model include its high price.

• RedVerg RD-C95T. Vibratory rammer of Chinese production weighing 95 kg, equipped with a 4-stroke gasoline engine Loncin 200F with a capacity of 6.5 liters. with. The compaction depth is 30-35 cm. The device has an irrigation system that allows you to work not only with bulk, but also with bituminous materials. The disadvantages of the model include the lack of reverse motion.

When buying a vibratory rammer, there are several important parameters to consider. The choice of equipment depends on the type of work that needs to be done. In accordance with them, the mass of equipment is selected. For solving everyday tasks, light or medium-weight units are suitable. It is best to give preference to devices with a small platform area - they have low performance, but they are durable. Equipment with heavy and embossed slabs is suitable for working with bulk building materials. For asphalt, choosing a vehicle with a small, smooth shoe is the best solution.

When choosing a rammer, it is worth considering its economy - fuel consumption depends on it. It is preferable that the device is equipped with an irrigation system, as it provides ease of use. Vibratory rammers supporting this function do not adhere to sticky soil. When compaction of materials with equipment with an irrigation system, the compaction is better.

If you plan to carry out work in a limited space (narrow passages, trenches), it is recommended to take a closer look at models with a reverse option. In other cases, it makes no sense to overpay for this function. If you need to frequently move equipment from one construction site to another, it is better to choose models with transport wheels. Before buying, you need to carefully read all the technical characteristics of the vibrating plate and other documentation from the manufacturer.

Modern models of vibratory rammers can be filled with A-92 and A-95 gasoline. And you should also use engine oil with an optimal viscosity.After refueling the equipment, check for fuel leaks. The equipment must be started according to the instructions, warm it up for 3 minutes, letting it run at idle speed. When you press the rev lever, the rammer will begin to move forward, compacting the loose soil.

When working with equipment, the operator should always be behind it. Extreme care must be taken when turning the equipment. To maintain health, it is recommended to use respirators, goggles and hearing protection.
