Description

The power head rotation and thrusting / pulling can be adjusted arbitrarily in variable speed from zero to maximum. Power head rotation adopts closed-circuit system, thrusting-pulling and auxiliary system adopts load sensor system, all the systems used are volume speed regulating system, high transmission efhciency, less heat, low oil temperature, achieving energy saving eventually. Pulling force can reach 120 tons, eguipped with large chassis, walking controlled by Danfoss inlet handle, stable and safe, large displacement water pump can directly drive mud motor for rock drilling.
