HC725 Crawler Mining Site Blasting Stone Drill Rig 

Crawler type hydraulic drilling rig is a hydraulic DTH drilling equipment with a self-propelled feature, in addition to DTH hammer using air power, the rest of the power provided by the hydraulic station.
Mainly used for mining, quarrying, railway, transportation, water, building materials, military and other outdoor projects blast hole drilling in deep,high efficiency drilling operations. Also widely used in bolting, channel excavation, sewer engineering drilling operations.


1,Thruster propulsion fuel tank, with a high lifting force;
2,Use two large flow air filter, effectively protect the life of the diesel engine;
3,Adopt international advanced hydraulic components, hydraulic system more reliable and efficient;,
4,Guide the use of the slider sliding, making rail more resistant;
5,Dual motor reducer rotating mechanism, ensuring high reliability and greater torque.
