China Trailer Type Water Well Geological Prospecting Mining Drilling Rig

TRAILER TYPE CORE DRILLING RIG

Series spindle type core drilling rigs are mounted on trailer with four hydraulic jacks, self-erect mast by hydraulic control, which are mainly used for core drilling, soil investigation, small water well and diamond bit drilling.

MAIN FEATURE:

Compact size and light weight of mechanical transmission, large diameter of rotating, unit's spindle, long distance of support span and good rigidity, hexagonal Kelly ensure the torque transfer.

The trailer is equipped with radial tyres, and four hydraulic supporting jacks, which is used for leveling the drill before working and strength the stability of rig.

The hydraulic mast is composed of main mast and mast extension, which greatly improve working efficiency, and are very easy for transportation and operation. Compared with common core drilling rig, trailer type core drilling rigs have put off heavy derrick and save cost.

With high and optimum rotating speed, the rig can meet various requirement of small diameter diamond drilling, large diameter carbide drilling and all kinds of the engineering hole drilling.

During the feeding process, the hydraulic system could adjust the feeding speed and pressure to meet requirements of drilling in various stratums.

A bottom-hole pressure gauge is equipped to monitor the drilling pressure.

Automobile type transmission and clutch is equipped to achieve good commonality and easy maintenance.

Centralized control panel makes operation convenient.

The octagonal structure spindle is more suitable to transmission in large torque.
