BM 831 drilling and piling machine

Manufacturer Altailesmash

Condition is new.

The BM-831 drilling and piling machine is designed for drilling wells and driving piles into them during the construction of pile foundations of buildings and structures, as well as the installation of wooden and reinforced concrete supports, metal pipes, and during the construction of power transmission and communication lines. The MTCH-4 base chassis allows the BM-831 to carry out work in difficult and hard-to-reach places.

Advantages

BM-831 has the ability to drive piles into drilled holes without re-equipment, without changing position, and drill wells up to 15 meters deep in one pass with a continuous auger drill. Diesel hammers SP74A and SP75A allow driving piles up to 8 m long without a leading hole and up to 16 m long with a leading hole.

Operation of the machine is allowed in areas with a temperate climate in the ambient temperature range from minus 40°C to plus 40°C.
