SE21 High Torque Small Backlash Worm Gear Slew Drive With Hydraulic Motors For Mining Machinery
Product Description
Slew drive driven by hydraulic motor is an ideal driving component for truck crane, crawler crane, ship crane and excavator, and other wheeling equipment. The structure is quite compact, and is of high IP grade which can suit those IP-critical equipment.
Slew drives with hydraulic motors are mainly applied in port machinery, mining machinery, welding machinery, construction vehicles, modular vehicles, wind power systems etc.
