Yulan Street, High-tech Zone, Zhengzhou City, Henan Province, China.
1. 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.
2. Adopting electrical and manual control of operation valve group, mported from USA, the main Sauer control valve is very reliable.
3. 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
4. Adopting two-low- speed and large torque motor made by Poclain Hydraulics Industrie SAS, France for the rotation of drill head; set with 2 gear stepless speed adjustment function, floating of spindle is helpful for protection of rod thread
5. Four groups of hydraulic motors made by Sauer, USA and reducers made by Dinamicoil Co., Ltd, Italy are adopted for combined driving to the drill head for its push and pull; adopting rack and pinion transmission structure, the rig is in high stability and efficiency,
6. Installed with operation cabin, equipped with air conditioner, the rig is easy to operate in a comfortable working environment.
7. 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
8. Adopting traveling reducer made by Doosan Group, Korea, the crawlers are provided with strong force and good grade ability.
