BD DRILL – HJG-W850A WATER WELL DRILLING MACHINE

image001


HJG-W series drilling rig is an versatile internal combustion-driven crawler hydraulic drilling rig that is designed and manufactured elaborately by Changsha Heijingang Industrial Co., Ltd. To ensure the stability of the rig’s performance, the key components are imported. The maximum drilling depth of the rig is up to 500 meters and drilling range is between 105-350mm in diameter. The rig can meet needs under the different geological environments for geothermal projects, the exploration of groundwater, hydro-geological exploration, pile construction and some other projects’ needs. The whole rig is advantageous with a more powerful engine, bigger output torque, higher working efficiency and flexibility, as well as better stability and multi-functions, etc.

 

Main characteristic of HJG-W850A:

1. Rotary head: Brand: EATON (U.S. Brand)

Rotary power head mounted on the drill, a rotary elecro-hydraulic valve controls two hydraulic motors, enabling rotation speed and the two kinds of gearbox output torque to enable rig adapt to different working conditions.
