Horizontal Mounted Hydraulic Slew Drive With Self Lock Function For
Car Crane
Hydraulic Slew Drive Description
The slew drive device can be basically divided into single worm
drive slew drive device and double worm slew drive device.
The product can be used for flat-panel transporter, crane, and
single column crane, lift lifting, with car crane, aerial vehicle,
day cruise solar energy, automation equipment and other mechanical
equipment. In the solar photovoltaic power generation industry,
slew drives are generally equipped with DC planetary motor or AC
reducer motor, and the hydraulic motor is used as the power drive
system on the construction machinery.

Features
The slewing drive is a gearbox that can safely hold radial and
axial loads, as well as transmit a torque for rotating. The
rotation can be in a single axis or in multiple axes together.
Application
This hydraulic slewing drive adopts compact design, which
facilitates both installation and maintenance. All these advantages
make the slewing drive suitable for a variety of construction
vehicles, crawler excavators, aerial platform vehicles, tracked
vehicles, and so on.
