MWLH800 Full hydraulic core drilling rig

Product Introduction

Rotation Head
Rotation head adopts mechanical two-speed stepless speed regulation design. The low-speed torque is multiplied, and the drilling is stable and reliable. The rotation head is equipped with a lateral translation mechanism, which is convenient for lifting and releasing the drilling tool.

Hydraulic Motor
The hydraulic motor has the characteristics of compact structure, small size, impact resistance, long life and large torque, which greatly improves drilling efficiency.

Power Part
Adopting Yuchai turbocharged engine and triple gear pump full hydraulic drive, the system pressure is high and the power output is strong.

Structural Part
The crawler of the drilling rig adopts a low-speed high-torque hydraulic motor, wireless remote control walking, high safety performance, strong climbing ability, and the moving speed of the whole machine can reach 2Km/h, which is suitable for transition and operation in mountainous areas and muddy ground.

Hydraulic System
The hydraulic system is equipped with double hydraulic oil filtration, two-stage air cooling +one-stage water cooling system, which ensures the heat balance and cleanliness of the hydraulic system, and greatly improves the stability and durability of the drilling rig. The hydraulic hose adopts two-layer steel wire braided high-pressure hose, plus a protective sleeve, which is wear-resistant.
