1. Brief introductions of YQZ-30 hydraulic core drilling rig

YQZ-30 hydraulic core drilling rig is a small portable diesel oil drilling machine. It is mainly used for prospecting and exploration, geophysical exploration,drilling engineering such as road construction and blasting hole, shallow oil, natural gas and groundwater drilling. It also can be used for engineering drilling of dam grouting and tunnel ventilation and drainage. The drilling depth of YQZ-30  hydraulic core drilling rig is 30 meters. The open hole diameter is 89mm, and the final hole diameter is 75mm.

2.Features of YQZ-30 hydraulic core drilling rig

· Oil pressure automatic feeding mechanism, high drilling efficiency.

· Using the upper ball clamp mechanism, non-stop re-chuck

· Handles are centralized, easy to operate, safe and reliable.

· Compact structure, small floor space.

· The shell of drill rig and gearbox are made of aluminum. The shell reduce the weight of the fuselage.

·  Easy to decomposition and move, suitable for working in hilly terrain, mountainous areas and other complex terrain.
