2020 New design for hydraulic crawler rock drilling rigs

The diesel engine is changed to vertical

KHITAN-910-DTH down the hole hydraulic crawler rock drill with most advanced powerful technology.

1. More refined, the overall layout has also changed
2. The diesel engine is modified to vertical to solve the problem that the horizontal engine radiator was too close to the driller.
3. Added tubing reel to meet borehole requirements for horizontal holes
4. Besides, the number of work lights is also relatively large, and they should be constructed at night.

China famous disesel engine YUCHAI

Rotary torque 1750-4200 Nm

Easier operation within 1 day
