Major features:
It's an electric-driven all-trailer rig, of which all modules equip trailer-transportation device, so it has high transportation performance and suitable for oilfields in desert zones.
According to different road conditions, mast and substructure can be trailer-transported as a whole or separately.
During mast trailer-transportation, top drive may stay in it.
Substructure trailer device equips turning system to ensure the safety of trailer-transportation.
It has all operation capacity and advantages of DC electric rig.
