Product Description
Key Features
4-Speed Gearbox & 0-90° Angle: Top Drive Head for All Drilling Bits
Top drive head suits for tricone bit, DTH hammer, PDC Dill bit and diamond bit which meets special demand of rotate speed and torque during work. The 4-shift Gearbox using spur gear drive, oil bath lubrication. Hydraulic Motor and gearbox could provide for much high speed and torque to be adjusted. The angle of rotate unit could be adjusted as needed, ranges from 0º（vertical）--90º. Internal diameter of faucet core shaft: 76.2 mm
Intelligent, High-Reliability Hydraulic System with Triple Variable Pumps & Complete Filtration
Four hydraulic pumps, three variable displacement piston pumps and one fixed displacement hydraulic pumps, all together provide power for the rig. The hydraulic system is an open circuit with proportional control valve and completely circuit filter unit. The filter element can be replaced. The heat dissipation of hydraulic is from forced air cooling. Variable displacement piston pump and proportional control valve of rotating and feeding system are load-sensitive designed, which controls the flow of pump as required. All hydraulic branches are protected by overflow valve.
