1, Full hydraulic drive, steel Crawlers, assembly type mast, the machine is integrated and compact for easy operation in structure consisting of power station, main hoist, wire line winch and mud pump, etc.
2. lt is adopted dual pump and motor and closed-loop hydraulic circuits for rotation of unit head: and open-loop design is adopted for all other hydraulic transmission, lt is adopted precursor control and load-sensing for the hydraulic system, The system is controlled by electro-hydraulic proportional integratedly and intensively.
3. The structure of doubling system between cylinder & chain is adopted for the feeding and lifting of drill head, i.e, with the function.if the piston rod of oil cylinder moving one certain distance, the spindle movement will double the distance, Lifting capacity and feeding capacity is separately up to to 295 kN , 152kN .
