HFT350B Truck-mounted Water Well Drilling Rig

overview

►Description:
This rig is a rotary drilling rig with directional circulation, which is equipped with BW900/25 mud pump, It adopts the slurry as the washing fluid, it can drill on clay, sand and rock if it is equipped with a good drilling bit.
1. The power of drilling rig comes from the truck engine, the rig setups distribute implement and hydraulic system.
2. The appearance of rig is pretty, it has a high efficiency because of having a larger torque of the turntable, it is mainly used for water well, construction, national defense building foundation, geological exploration, geothermic well and other foundation working.
