The upper chassis adopts modern production process,which is extra-large space, electro-hydraulic separation design, and is equipped with American Cummins QSX15 engine with a maximum power of 380kW.
The under carriage adopts the special design of rotary drilling rig, with H-type telescopic structure ,easy for transportation.
The Center-mounted winch with single-layer rope design increases the life of the wire rope and long-term heavy loads. Pin connection for easy operation and maintenance.
The rotary head is large torque and multi-layer buffer structure design, which effectively reduces the damage of the rotary head caused by the impact of the kelly bar.
The crowd system system is available for crowd cylinder type as standard, and crowd winch type is optional.
The mast is high strength and good straightness. The installation positions of the upper and middle masts are interchangeable. The option of crowd winch type can be used to adjust the strokes.
The mast head is high strength materilas and simple structure.
Large triangle structure support system ensure best stability.
With small turning radius, variable combination and superimposed counterweight, which adjust according to working conditions, easy to disassemble and convenient to transport.
