The key components of the rig's hydraulic system, including the hydraulic oil pump for rotation and feed, as well as the control handle, are all imported Danfoss products. The power head rotation adopts a French Poclain motor, featuring high rotation speed, high efficiency, large torque, and low failure rate. The feed mechanism uses a rack-and-pinion drive system powered by a motor with a reducer. When equipped with the optional force-boosting system, the maximum feed and pull-back force can reach 90 tons, making it convenient to handle partial obstructions during pipe dragging in a timely manner and minimizing potential losses. This small machine is paired with a large-displacement mud pump to meet the requirements of large-diameter reaming.
