Features1. The truck chassis adopts the special crane chassis of brand SINO TRUCK and the main drive system,Website:http://www.rejeedrilling.com, the transfer case, gearbox, double-winch unit, mud pump, turntable, drilling tower, feed mechanism are set up on the chassis.2. This water well drilling rig is a rotary drilling rig with directional circulation. It is equipped with mud pump which adopts the slurry as the washing fluid and can drill on clay, sand and rock if it is equipped with suitable drilling bit.3. The power of truck engine transfer to PTO, and then drive drilling rig.4. The main drive of this water well drilling rig is mechanical and the four landing legs and drilling tower are hydraulic controlled. Transfer case and mud pump clutch system are air operated.5.  According to client's requirement, the water well drilling rig can carry out down-the-hole hammer drilling with Air Compressor.6.  It is high efficiency because of having a larger torque of the turntable and is mainly used for water well in industry and agriculture, national defense building foundation, geological exploration, and geothermic well and other foundation working, it is popular at home and abroad.
