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

Geological survey and exploration, road and high-rise building foundation exploration, and all kinds of concrete structure inspection holes, river embankments, subgrade grouting holes, drilling and direct grouting, civil water well and ground temperature central air conditioners.

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

· adopts 53*59 hexagon drilling, which has high rigidity and strong delivery torque.

· the machine is equipped with taper clutch, with the charactristics of strong transmission troque, easy operation and free of maintenance.

· for the winch, we use large module planetary gear and add supporting frame, greatly increasing hoisting and braking ability of the winch.

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

· we are the first one to equip mud pump with the flow 160L/min in China so that it will save cost and also make the machine compct, moblie and light in weight.
