Technical parameters of 260 crawler pneumatic well drilling rig

1. 260m DTH Crawler Mounted Well Drilling Rig is compact, and its width is only 1.3m, suitable for narrow drilling condition, and the max drilling depth could reach 200m.

2.Perfect Maneuverability with hydraulic control.

In order to fulfill various application cases, the main parameters of drill can be adjusted, such as rotation speed, torque, feeding pressure anti-feeding pressure, feeding speed, lifting speed.

3.Rotation, feeding, lifting by Top driven.

Easier for rod changing, reducing rod changing time, better for follow – down drilling.

4. Multi-functional drilling

Multiple drilling ways could be worked on this rig, such as DTH drilling, anti-air circulation drilling, anchor drilling, rotation drilling, and follow-down drilling, as well as core drilling.

There are optional parts added per customers'needs, such as mud pump, foam pump, generator as well as different types of winches.

5. Low operation cost

Down the hole drilling for rocks has the lowest drilling cost with highest level of working productivity.

6. Crawler chassis with long stroke jack cylinders

Long stroke jack cylinders are easy for truck self loading during transportation, and crawlers are of better mobility in mud working sites.

7.Adjustable feeding pressure to get the best feeding force at various drilling depths.

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.
