High Pressure Crawler Drilling Rig

Our KY140A/D high pressure crawler drilling rig is well designed for various working environments. Its working performance has been recognized by many customers.

1. Safe and stable walking mechanism

This kind of rock drilling machine has low barycenter and large ground clearance, so it can walk on bumpy round easily. The gradeability is strong and the fault rate is quite low, making the high pressure crawler drilling rig suitable for bad working environment. No additional air compressor is needed for walking.

2. Powerful driving system
A famous brand four-cylinder is adopted, and its driving power is super high. A patented air in-flow adjuster is applied to the diesel engine. The prefilter, fuel filter, and filtering paper make an excellent combination, which has greatly enhanced the environmental adaptability of this crawler drill and the service life of the engine.

3. Powerful driving and rotating mechanisms
The driving mechanism our this powerful drilling machine consists of a hydraulic oil cylinder and fall block. The lifting force of our high pressure crawler drilling rig can reach 20KN. By adjusting the pressure adjusting valve on the driving regulating valve, you can achieve a proper driving force.
