30 Hydraulic Core Drilling Rig

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

YQZ-30 hydraulic portable drilling rig is a small and light hydraulic drilling machine fed by oil pressure, mainly used for general survey, geophysical exploration, road and construction drilling, shallow oil, natural gas and groundwater drilling, and can be used for drilling of dam grouting, tunnel ventilation and drainage. The rated drilling depth of YQZ-30 hydraulic portable drilling rig is 30 meters, the opening diameter is allowed to be 91mm, and the final hole diameter is 75mm.

2. Features of YQZ-30 hydraulic portable core drilling rig

• With oil pressure automatic feeding mechanism, high drilling efficiency.
• With the ball card clamping mechanism, the rod can be turned down without stopping.
• The handle is centralized, convenient to operate, safe and feasible.
• Compact structure and small floor space.
• The casing of the rig gyrator and gearbox is made of aluminum alloy, which reduces the weight of the fuselage.
• Strong decomposition ability, easy to relocate, suitable for hilly, mountainous and other complex terrain work.
