Function / job

Transport of jumbo slabs in aerated concrete production

Special features

The tongs consist of two grip units which can be axially moved via a synchronous belt drive. The distance between the grip units is adjusted by a spindle drive. Grip arms which are offset against each other allow a maximum clamping range. The grip units are powered by a hydraulic unit integrated in the tongs frame. The clamping force can be steplessly adjusted. The complete tongs are taken up by an existing transport clamp and connection to the crane control is established through quick couplings. When the tandem tongs are not used, they are placed into a special parking frame and disengaged. The set-up time is only about 5 min.
