Product Description

Hc725 Pneumatic-Hydraulic Crawler DTH Drilling Rig for Mining

The Usage of Portable Crawler Rotary Drilling Rig:  

 1.This series machine are used in a wide variety of Quarry ,Highway , Water and electricity , Surface mine and deep hole joint pipe drill work on the building project etc.
 2.This series drilling rigs with air compressor,hammer together work , To blasting horizontal hole ,vertical holes ,inclines holes .

Advantage of HC725 Rotary drilling rig :

1. Low speed high torque hydraulic motor drive rotary device output torque required drilling operations.
2. The cylinder advance, so promoting a more stable, the failure rate is also significantly lower than the motor propulsion.
3. two filter effectively ensure the safety of diesel engine intake and prolong engine life.
4. can readily monitor rig hydraulic system pressure and boost pressure to ensure the rig stable and efficient operation.
