For compaction of the soil during construction or road works, a rammer is used in landscape design . Compaction occurs due to the fall of the working platform, which can have a different shape (rectangle, circle or square). Depending on the design, the tamper can be of several types.
- Units with a free fall of the slab, which is lifted by means of a cam or rack or wire rope mechanism. This is the lowest productive group: the frequency of the load fall is about 10 beats / min
- Explosive ramming machine receives energy when burning fuel.
- Auto-ramming units operate due to a cam or crank mechanism that returns the load to its original position.
- The pneumatic ramming machine for raising the slab uses the energy of compressed air. The maximum frequency of the load falling is about 1000 beats / min.
According to the impact energy, these mechanisms are divided into three groups.
- Heavy ones have impact energy from 1000 to 5000 kg / m (50 000 J).
- Medium - impact from 100 to 1000 kg / m (1000-10 000 J).
- Lungs affect the soil with a force of 80-100 kg / m (up to 1000 J).
A heavy ramming machine is usually made on a tractor, the weight of the working platform can be up to 3 tons, and the height from which it falls is up to 2.5 meters. The frequency of impacts for this type of mechanism is small.
Middle-class machines are based on
self-propelled chassis or in the form of trailed tractor equipment. There are self-propelled options in this group. Lightweight rammers are lightweight and manually operated. The most common model in this group is gasoline. Small dimensions and ease of management allow you to use them in places inaccessible to other devices.
According to the method of transferring energy to the ground, there are two types of tampers: with or without a rampart. Shabot - a metal plate laid on the ground, which accounts for the impact of the working surface. Shabotny cars have low efficiency, besides there is a probability of breakage of a plate therefore such cars usually have a small power.
Asphalt laying, compaction of the soil during construction or landscape planning, laying of paving slabs and many other works - this is the area where the rammer can be used. The price depends on the power of the unit, engine type, version and manufacturer. The price range is significant even in the light class: the cheapest manual unit can be purchased for $ 600-700, the most expensive representative of this type of machine costs $ 13,000-15,000.
On the acquisition of "tamper" is worth considering if you plan to use the unit continuously, but if the use is episodic, then you can use the rental services of construction equipment. There are organizations that offer tamper hire for a fee. Preliminarily find out the class and power of the necessary equipment, prepare the site for work and proceed with the search for the necessary equipment. The cost of renting construction equipment is calculated based on the time for which the unit is provided to you, and its cost.
