Advantages
· The rotating and thrusting motors both use Poclain large torque motors, stable performance, high effciency, safe and reliable application.
· The gripper can be moved throughout the process, convenient construction of the casing, easy to use the gripper to unload the drilling tool.
· The gripper increases the unloading torque, reduces the risk of stuck drilling, optimizes the valve road layout, makes the gripper control faster, the oil circuit more smooth, and improves the construction efficiency.
· The thrusting design increases the free wheel control system, one-button switch, intelligent control of high and low speed, which improve the system efficiency.
· Using LCD display screen, artificial intelligence system, easy to operate, intelligent storage of data, multi-work page intelligent switch.
