The length-wise moving beam is either actuated by a motor, a hydraulic actuator or manually. Loads, e.g. bundles and rolls, may be attached to the beam by straps, chains, ropes, or magnets; magnets directly connected to its beam by flexible (e.g. chain-) suspensions.

The beams are robustly engineered for heavy duty application to meet the severe demands of steel- and paper mills, or distribution- and service centers.
The beam itself is suspended to the crane trolley either by hooks or sheave blocks. Customized suspensions on request.
