Description

Power unit is the transmission device of rotary drilling rig. When the rotary drilling rig is working, the power unit will drive the drill rotating through its drive drill rod and provide thrust and lifting force. The input of power unit connects hydraulic motor and planetary reducer. And the rotation speed and torque can be adjusted automatically according to the different geological conditions. The output connects friction-type drill rod. It drives the drill working and meets the changing condition. We can do variant design of power unit and equip single speed or double speed planetary reducer according to requirements of our customer.
