The new generation of crawler pulling unit integrates the electric drawworks, electric control system, power battery pack, cab and other components into the hydraulic crawler chassis, which is suitable for well pad workover operations with muddy, potholes and other poor road conditions.

1. Chassis driving is powered by battery, and operation is powered by battery + well pad transformer power supply. Electric drive under all working conditions is with energy saving, environmental protection and zero emission.

2. It adopts hydraulic crawler chassis, stepless speed regulation, stable driving and good trafficability.

3. The maximum single rope tension is 120KN, which is equivalent to the lifting capacity of XJ700 workover rig.
