Technical parameters of 260 crawler pneumatic well drilling rig

1. Large diameter, deep drilling, fast footage, flexible and efficient. Equipped with large torque hydraulic motor and large diameter hydraulic cylinder propulsion, the design of * * pump group is convenient for maintenance.
2. The drilling rig adopts crawler chassis of excavator, with strong off-road ability, independent modular design and excellent mobility.
3. Combined positioner can be adjusted and replaced according to different types of drill pipe and impactor to ensure accurate positioning and centering.
4. The chassis is equipped with four high-strength hydraulic high outriggers with strong bearing capacity. The supporting height of the outriggers can reach 1.5m. The loading and unloading truck can reduce the hoisting cost and can be used as a leveling and stabilizing drilling rig.
5. The hoisting mechanism is convenient for the hoisting of drilling tools, reduces the labor intensity of the operator, and saves time and labor

Advantages of well drilling truck:

1. Full hydraulic control, easy to operate, easy to move, good mobility, time-saving and labor-saving.
2. The rotary device of drilling rig is driven by hydraulic motor, with large output torque and lower rotary center than similar products, which greatly improves the drilling stability of drilling rig.
3. The new variable angle mechanism makes the hole more convenient and the adjustment range larger, which can reduce the requirements of the working face.
4. It can be used with the pipe following drilling tools, drilling, hole quality is good.
5. JK series is a full hydraulic rotary well drilling rig with modular structure, which can be equipped with crawler or wheel traction.
6. Lifting power; The design of composite boom has the advantages of small volume, long stroke, double oil cylinder lifting and large lifting tonnage;
7. The lifting boom of each drilling rig is equipped with a limiter to protect the oil cylinder and ensure the work;
8. Each hydraulic oil pipe is wrapped with a protective jacket to prolong the service life of the oil pipe.
