HZ-200YY Hydraulic Core Drilling Rig

1. Applications of HZ-200YY hydraulic core drilling rig

HZ-200YY hydraulic core drilling rig is mainly used for geological general investigation and exploration, road and tall building foundation exploration, holes in concrete structure, river levees, civil water wells and ground temperature central air-conditioner.

2. Features of HZ-200YY hydraulic core drilling rig

the highest speed can reach 1045r/min with 5 gears, which improves drilling efficiency

adopted 53*59 drilling rod, which has high rigidity and strong delivery torque.

equipped with national patent technology-taper clutch, made the machine easy to operate and free of maintenance.

using large module planetary gear and adding supporting frame, which highly increased hoisting and braking ability of the winch.

vertical spindle are fixed by four groups of bearings to ensure that the core drilling rig is rigid enough for gravel layer and other complex geological conditions.
