1 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.
2 Driven by independent diesel engine, this drilling rig is powerful and full of great force.
3 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.
4 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.
5 The drill tower applies telescopic structure of internal and external towers whose positioning can be finished through hydraulic cylinder.
6 This drilling rig is fitted with a 50kW generator which is convenient for customers to perform drilling operations.
