KW Kranwerke - Crane With Motor Grab

The overhead traveling cranes are equipped with a trolley and a single-drum hoist unit. The grab is suspended using suspension chains on 4 parallel single ropes. This stabilises the grab and protects it from rotating. This approach also minimises damage to the cable reeling drum, increases operating safety, and facilitates maintenance due to the lower rope weight. It is now standard for all motor grabs to come with monitoring tools for control, such as motor temperature.
