Features
1. Dual rotary motor
The KW400 multipurpose geothermal water well drilling rig is driven by hydraulic motor from international famous brand. The straight gear reducer sleeve provides powerful rotary torque for the drilling rig and reduces the blocking rate of the rig. Thus it can ensure that there is enough torque during well drilling with certain depth.

2. Centralized operating system
The internal hydraulic control system can ensure the reliability and long term working performance of the drilling rig. The rig also adopts thrust lever handle of which the adjustment can be convenient. The adjustment can be conducted according to different working conditions.

3. Dual thrust oil cylinder
The drilling rig has two high pressure thrust oil cylinder with large diameter and large stroke so that it can ensure that the drilling rig has strong and powerful lifting capability and propulsion. Meanwhile, it can be matched with the two stage telescopic carriage to ensure that there is enough space for steering engine. So the drill pipe and sleeve assembly and dis-assembly can be easy.

4. Two stage filtering device of the diesel engine
The two stage filtering device of the diesel engine can be matched with the air inlet device connecting with compressed air. Thus it can ensure clean air source of the diesel engine. And the drilling rig failure can be reduced and the service life of the diesel engine can be prolonged.

5. Safe and reliable travelling mechanism
The propel machinery adopts high intensity base plate and is driven by wheel hub motor. It has strong climbing performance and low failure rate.

6. Triple pump
The drilling rig adopts high pressure triple pump from famous brand. The pump is directly connected with the diesel engine so the structure
