Application

Hydraulic core drilling rig is suitable to use in plains, hills, high temperature as well as low temperature places. The main machine is integrated in structure, which consists of self-propelled chassis, power, mud pump and hoist, etc.

Features

1. The maximum torque is 7200Nm (5307 lbf ft), which will be much more suitable for large dia. drilling in coal bed methane, hydrology and water well.
2. According to many years of experience in HDD field, our engineers install clamp and shackle device on the rig to relieve labor intensity, improve drilling efficiency and guarantee operator's safety.
3. Hydraulic core drilling rig is excellent in performance, high in working efficiency, easy for operation and keeps the operators from dangers.
