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.
