Slew drive MER21 - Dimensions
The slew drive enables unlimited and stepless rotational movement without slipping while supporting heavy loads. A well-controlled and stable rotation makes work safer and more efficient. Work becomes easier and faster when you can reach around corners and obstacles and require less repositioning of the machine.
What are the axial-, radial load and tilting moment?
Axial load is parallel to the axis of slewing ring.
Radial load means vertical load to the axis of slewing ring.
Tilting moment is the load multiplied by the distance between the position of load and the center of slewing ring. If the torque generated by load and distance is greater than the rated tilting moment torque, slewing drive will be overturned.
