Numerical meter display the working torque, push or pull force and so on parametric in working conditions. Electronic sensor has rapid reaction and can show overload immediately. It also endures accuracy and delay of the traditional hydraulic meter’s indication. It solve the matter to depend the operator to calculate the torque and force by the equipment’s switch directive.
Drill frame slide by the cylinder. Combine with link weldment. It is easy safe and simple to adjust the entry angle of the equipment. The gearbox adopts three methods to avoid the strike on the end of the drill frame. So it is more safety to the HDD.
Dual-engines are used. The HDD has all the motion on the condition of any engine starting. Multi-condition technology of adjusting the travel speed combining with the multi-speed control of rotation and push or pull make HDD be suitable to the complex geology. You can use one engine in the condition of small pipe diameter in order to reduce the fuel consume. So it is inexpensive in construction.
Clamp can travel on the drill frame. It has the future of big torque and convenience of cathead. The HDD adopt the patent of rotation tooth. It is easy to achieve in clipping the pipe. It is reliable in clamping.
The HDD adopt Overload protection. Torque and force and cylinder can adjust by the digital technique. It is easy and simple to adjust. and can be betoken in advance.
The HDD’s rotation adopt closed hydraulic system and it’s push or pull adopt load sensitivity technology. The main part of hydraulic and electric and transmission are made of world first-class brand products, good performance, good reliability
