Hydraulic crawler drill machine|Air Compression open-air DTH drilling rig

"Zhongtuo" brand ZT5-type open-air DTH drilling rig is an advanced drilling equipment that integrates the downhole drilling system and the screw air compression system. It has compact structure, good integrity and easy movement. The drill has energy-saving efficient, safe and environmentally friendly, flexible, easy to operate, stable performance and so on. Specific performance is as follows:

1, large displacement hydraulic pump installed directly on the engine after the take-off port, simple structure to reduce the source of the fault.

2, large-scale luffing boom system to meet the needs of different working conditions in various conditions, in particular, can play low horizontal hole.

3, highly integrated hydraulic control system and layout of the centralized operating platform, a station can freely manipulate the entire machine.

4, the drilling rig configuration rotary speed control valve, according to different characteristics of the rock being drilled and different conditions, can be adjusted in time, drilling speed, high porosity.

5, the machine is equipped with real-time monitoring system and a stable self-protection system, can accurately reflect and control the working status of the drilling car, beyond the set range and failure can automaticallyshut down.

Efficient two-stage dry dust collection system, greatly improving the working environment, in line with the concept of energy saving and environmental protection.
