Slew drive MER21 - Measurements

hydraulic rotator mense mer21 measurements

The slew drive produces an unlimited and continuous slewing motion without slipping when supporting a heavy load. Well-controlled and steady slewing motion makes working safer and more efficient. Working gets easier and faster when it reaches behind corners and obstacles and less basic machine movement is needed.

What are the axial-, radial load and tilting moment?

Slew drive loads
Loads on the slew drive

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.
