HFJG-150 crawler anchor drill is a multi-function engineering drill that can be used for horizontal lifting and vertical multi-angle construction. According to the construction conditions of bolt support for complex deep foundation pit, the drilling rig is an engineering drilling rig which is satisfied with the support technology of deep foundation pit slope and the construction of rotary jet. It has the characteristics of good mobility, wide range of working holes, high efficiency, good drilling quality and low pollution.

Features:

1. The drilling rig is developed and produced on the basis of the original GM-5S drilling rig, which improves the power of the drilling rig, obtains higher torque and pulling force, has simple structure, convenient maintenance and worry.

2. The maximum horizontal lifting height is 3.0 meters, the minimum is 2.0 meters, and double rows of anchor cables can be constructed at one time.

3. can choose to match three different specifications of the hydraulic motor, so that the power head to obtain three different highest output torque and speed, to meet the different construction technology

4. can be equipped with rig crane, effectively reduce the labor intensity of workers, reduce labor costs.

5. the frame rotation using large diameter slewing support, when needed, the hole position can be easily transferred to the side of the track work.

6. can be matched with double gripper, effectively reduce the drill pipe loading and unloading labor intensity and operation time.

Achievable construction process:

1. Three wing bit drilling, mud discharge, suitable for soil and other strata high-speed drilling.

2. Small diameter twist drilling (≧200mm), suitable for soil layer.

3. Pneumatic drilling hammer drill, air slag discharge. Suitable for rock layer, broken layer construction.

4. Casing drilling.

5. Casing, drill pipe composite drilling.

6. Single, double, triple rotary spray construction.
