XZ2860 XCMG HDD Directional Drilling  Technical specification

Product model:  XZ2860 XCMG HDD Directional Drilling

Manufacturer: XCMG GROUP

XZ2860  XCMG  HDD Directional Drilling  is one-piece and full-drive horizontal directional drilling machine, which can choose the independent operating room. The machine adopts Closed loop circuit, the electro-hydraulic proportional control, load sensitive control, a number of advanced control technology and the company's proprietary technology. The main technical parameters and the  control technology have reached the international advanced level. The main components such as hydraulic system, transmission system, reducer, electric control system choose the international brand-name products with the high reliability.
 
I. The highlights

1.Digital instrument can automatically display actual torque when working and the push&pull forces. Electronic sensor technology is sensitive and it can timely feedback instantaneous overload, and reliably protect of drilling rig; digital instrument overcomes the inaccurate, slow response, the need for manual gear torque conversion according to the construction and disadvantages of push pull indication of the traditional pressure meter.

2.The drilling frame slip rely on push-pull cylinder. Combining with the front arm drill penetration angle adjusting structure, simple operation, safe and convenient. The three limit impact free limit technology is used to limit the drilling rig.

3.Dual power system, either engine starts can confirm whole working requirement.The XZ2860 XCMG HDD directional drilling can work in different terrain by multi working condition adjust technology and multi-gears control syste on rotation and push&pull.If the small diameter channel construction needed,only one engine start can save fuel and reduce the cost.

4.Full floating vise,high torque shackle clamp make laying up sleeve pipe easily.The patent rotation vise seat make it easy to find center and clamp tightly.

5.Overload protection technology, drilling rig rotary torque, push&pull and clamping vice  are using digital pressure regulating technology, convenient adjustment, simple and accurate preset.

6.Closed Rotating hydraulic system, Sensitive loading controlled push&pull with international well-known brand components such as hydraulic,electronic device and transmission device make quality reliable.
