USV-120 PILE-DRIVING EXCAVATOR MOUNTED PLANT

A special self-propelled machine has been created which provides static pressing-in piles of any length and section with a pressing-in load of up to 90 tons.

Static pressing in the soil of a pile or a piling bar is a safe and simple way of arranging pile foundations and piling bar barriers. It excludes dynamic and vibration loads on both the constructions of nearby buildings and structures and the pile itself. It enables the use of piles with lower concrete mark which allows to save cement and diminishes steel rod expenditure.

The driving-in effort depends of the weight of the machine and it can be increased through adding load up to 100-120 tons. It is also possible to embed piles into previously bored holes which significantly diminishes the necessary pressing effort.

An essential advantage of this way consists in its full noiselessness which is of a particular importance during the execution of works in areas with already existing buildings. The relatively small dimensions allow the machine to work also in factory shops where reconstruction is being on and in other premises of a large volume. The drive and control of the machine are electrical hydraulic.

The plant is transported by a trailer of by railroad with partial disassembling in conformity with the transportation/traffic regulations. The manufactured plants correspond to the international level.

For manufacturing the plant, a standard machine-building enterprise infrastructure is used. Providing services on enterprise modernization on an agreed-upon basis, as well as joint finalizing the plant up to the customer’s request are possible.

At present, the subject plants are used in restoration works, in districts of old and museum buildings, as well as in course of Metro stations construction.
