4000m digital control VF electric rig

ZJ40/2250DBS drilling module


Main features of drilling rig:

The rig is designed integrated with mechanical, electric, hydraulic, pneumatic and digital control. It takes fully the advantages of digital control, AC VF electric transmission. So its mechanical structure has been simplified.

Electric transmission uses a vector VF drive system; fully digitalized operation and control are realized, automatic and intelligent operation and control functions as well. The control data and drilling data can be acquired (signal) , displayed, stored, printed, controlled and managed remotely.

The VF technology used makes Max. DW output torque at zero rotation speed to ensure the suspending function of rig hoisting system, which completely replaces traditional driller's operation mode.

Integrated driller's cabin makes the driller fulfill the main operation of drill rig in the cabin.
