21 Inches High Torque Worm Gear Drive With Hydraulic Motors For Mining Machinery
High Torque Worm Gear Drive 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. By adopting slewing bearing as its core component, slewing drive can bear axial force, radial force and tilting moment simultaneously. The slewing drive pair is easy to install, easy to maintain, and saves installation space to a greater extent. This product can be widely used in construction machinery and new energy fields such as heavy-duty flatbed trucks, container cranes, truck-mounted cranes, aerial work vehicles, solar power generator systems for sun patrols, etc. Slewing drives can be basically divided into single worm drive slewing drives and double worm drive slewing drives.
