Travelling mechanism of safety and stability
Low gravity center, large ground clearance, can be easily through the rough road.
Reliable automatic crawler leveling function and the parking brake (parking) system, not only make drill rig walk stability, and greatly reduced to the ground impact force of to the drill rig, ensure the driving safety.
Unique to take off the chain device, greatly improves the reliability of the working drilling rig.
Automotive diesel engine adaptability to bad environment and condition, without external air compressor can walk free, shift convenient.
Strong and reliable power
Using four cylinder diesel engines as power, traction power, strong climbing ability; the whole machine vibration is small, work smoothly.
Using patent "one kind of drilling rig diesel engine intake adjusting device" (patent no : 2008820087606.3) plus the prefilter, oil filter, filter paper triple filter perfect combination, to enhance the drilling rig adapt to bad environment, prolong the service life of diesel engine.
High power motor drive
High power hydraulic motor drive, strong climbing ability, has great tractive effort.
Strong propulsion, slewing mechanism
A new type of slewing mechanism composed of planetary gear reducer with cycloid hydraulic motor with high torque, provide powerful torque reserve for boring rig, reduce pipe-sticking probability.
The hydraulic oil cylinder with Movable pulley group combination of propulsion mechanism, can generate 20 KN lifting force, to adjust the propulsion control valve of regulating valve, the best propulsion can obtain conditions required.
