I. Main Structure Features

A. Adopting first-class hydraulic products in the world and the hydraulic circuit in closed for push-pull and rotation, and open for auxiliary circuit loading sensing system cooperating each other, and with electric-hydraulic proportional control in high efficiency. 

B. In split structure, the rig is in three parts consisting of power unit, main machine and cabin. It is easy for the rig’s transportation.

C. Pointers and electronic devices are adopted together for data showing of the rig, rig pressure, torque, rotation speed and push-pull capacities are clear at a glance.

D. Shackles can be adjusted for the space of making jaws and breaking jaws; breaker can be centered automatically, breaking accurately, stably and reliably and gripper can move on the mast full stroke.
