HZ-200YY hydraulic core drilling rig

1. 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 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
