Crane systems are equipped with adapted lifting components to lift special loads. In terms of the grabbers, a differentiation is made between positive locking and frictional locking.
For instance, electrical cylinders for positive-locking load lifting equipment are used; these are ‘slung’ around the part. An additional limitation of the maximum force of the electrical to lift cylindrical objects cylinder ensures protection against damage.
RACO electrical cylinders have the following options for limiting the setting force:
- Electronic shutdown by recording the motor current; realised via the RACO EWS 100
- Electronic shutdown by limiting performance; realised by the RACOmatic® in the configuration D ‘force controlled’
RACO electrical cylinders are also used for safe format changes on beams and locking of parts on load lifting equipment.
