Features
This drilling rig is one type of normal-circulation rotator. The chassis of full-trailers is applied in this drilling rig which is being equipped with all-steel meridian tires with good off-road performance.
Driven by independent diesel engine, this drilling rig is powerful and full of great force.
This drilling rig is equipped with two hoisters, so three-speed (fast-middle-slow) lifting and lowering can be achieved to improve working efficiency of well drilling by big lifting force.
This drilling rig is equipped with four hydraulic support legs and two mechanical support legs. Hydraulic mechanical double-locking can be realized by means of oil-cylinder piston rod of each hydraulic support leg. In this way, the chassis will not lose stability even if the oil-cylinder leaks.
The drill tower applies telescopic structure of internal and external towers whose positioning can be finished through hydraulic cylinder.

This drilling rig is fitted with a 50kW generator which is convenient for customers to perform drilling operations.
