Heavy load WH12 drive slewing gear reduction for excavator, timber grab and other rotation equipment

Slewing drives are widely used in aerospace area, solar power systems, wind turbines, satellite broadcasting system, and engineering machinery like truck cranes, and man lifts, etc. Recently years, it has been prosperously used in photovoltaic power generation systems, special vehicle, heavy-duty flat-panel truck, container cranes, truck mounted crane, automobile crane and aerial vehicles, cranes, gantry cranes, small wind power stations, space communications, satellite receiver, etc.

There are no special limitations of mounting angles and positions of this series of products.  It can be mounted horizontally, vertically and inclined.  Enclosed slewing drives are assembled of enclosed housing, slewing bearing, worm shaft and other parts.  Users can choose electric motors or hydraulic motors as the driving power.  It can slew 360 degrees clock-wise or otherwise.  The slewing drive is compact and it is also easy to mount and maintain in comparison with other types of driving devises.

It adopts enclosed design and the protection level can reach IP65.  It can effectively prevent dust, rain and other hostile environments.  It suits field usage such as desert, alpine and other hostile environments.
1.Products are easy to mount and maintain.
2.The design and mounting dimensions are international or domestic universal dimensions.  It is easy for the users' replacements in the future.

Tilting Moment Torque: Torque is the load multiplied by distance between the position of load and the center of slewing bearing. If the qorque generated by load and distance is greater than the rated tilting moment torque, slewing drive will be overturned.

Radial load: Load vertical to the axis of slewing bearing

Axial load: Load parallel to the axis of slewing bearing

Holding torque:It is the reverse torque.When the drive is rotating reversely, and parts are not damaged,The maximum torque achieved is called holding torque.

Self-locking: Only when loaded, the slewing drive is not able to reverse rotate and thus called self-locking.
