Safe and Stable Travelling System
This machine has low gravity center and big ground clearance, and can easily travel on bumpy road. It is driven by special wheel motor. That brings it strong grade-ability and low failure rate.
Equipped with advanced auto-balance and brake system, makes the crawler rock drill travel stably and also greatly reduce its impact force to ensure the drive safety.
Special anti-lock device greatly improves the crawler rock drill’s reliability.
Vehicle-mounted diesel engine provides strong power, so the crawler rock drill can freely travel without air compressor.
Adjustable boom
Boom is adjustable. The angle of drilling hole and height of horizontal hole can be adjusted by controlling the stretch-out and draw-back of the hydro-cylinder.
Powerful feed mechanism and rotating system
The new rotating system is composed of orbit hydraulic motor and planetary gearbox. That provides the crawler rock drill with strong torque reserve and reduce the sticking drilling rate.
The feed mechanism driven by high power hydraulic motor can generate 20 KN lifting power. Adjust the pressure regulating valve on the control valve can got the favorable driving power which is required by the working condition.
