Crane And Excavator Slewing

Slewing rings are one of the most important parts of cranes. The slewing ring provides the crane with its possibility to rotate while lifting loads. Naturally, slew ring has to be in good shape for the crane to fully function.

 

Slewing is the rotation of an object around an axis, usually the z axis. An example is a radar scanning 360 degrees by slewing around the z axis. This is also common terminology in astronomy. The process of rotating a telescope to observe a different region of the sky is referred to as slewing.

 

The term slewing is also found in motion control applications. Often the slew axis is combined with another axis to form a motion profile.

 

In crane terminology, slewing is the angular movement of a crane boom or crane jib in a horizontal plane.
