Rotary and Rotary Percussion Drilling All Hydraulic Crawler Rigs for Underground Coal Mines
Jun 24, 2016

Application scope

This rig is suitable for rotary and rotary percussion drilling, mainly used to drill gas boreholes, water detection and drainage boreholes, trenchless across street boreholes and bolting boreholes.

 

Structural Characteristics

There are three components of a drill rig: drill unit, pump station and control panel. The drills use an electric motor to power the hydraulics on the machine. The easy disassembly, lightweight and compact design make it convenient to transport and set up for spaces and locations where  mobility and quick set up time are important. The rotator is hole-through structure. The length of rod is not restricted by the structural dimension of the rig. The rig provides hands-free unloading of drill tools, linkage operation between the clipper, holder and the oil cylinder, as well as the rotator and the holder.

 

The rigs have stepless speed regulation, wide range of rotation speed and torque. They are easy and convenient to operate reducing operator fatigue and improving efficiency. The centralized operation on the control panel can keep the operator far away from the drilling orifice, providing a safe working environment.
