Powerful and Reliable Enginefor crawler drilling rigs

1. Adopt famous 4-cylinder diesel engine as driving force which has advantages of large power, powerful grade-ability, small vibration and reliable operation.

2. Adopt patent diesel engine air inlet regulating device(Patent No. : 200820087606.3)and desert air filter two-stage filter. That strengthens the crawler rock drill’s adaptability to severe environment and lengthened the diesel engine’s service life.

Adjustable boomfor crawler drilling rigs

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. That enlarges the drilling hole’s range and improve the machine’s adaptability.

Reliable hydraulic pump systemfor crawler drilling rigs

Oil supplied by two independent gear pumps, reliable operation, strong adaptability, easy maintenance.
Adopt gear transmission and soft connection, possessing compact structure and stable operation.

Reliable hydraulic system for crawler drilling rigs

1. Adopt special hydraulic components. That improves the system’s stability and reliability.

2. Install oil liquid cooling device, to eliminate the exothermic hydraulic oil’s influence to the system
