Electric stacker with expanding mandrel
Electric pedestrian stacker with expanding mandrel to take reels from the inner core and tilt it from vertical to horizontal and viceversa. The mandrel is closed by the hydraulic pressure and expands mechanically by means of springs placed inside the shaft when the oil is discharged. The mechanical system ensures the reel grip even in case of pressure loss or pipes breaking. Progressive controls by distributor levers and enable push button to activate the mandrel reduction with consequent release of the load (two hands control). The mandrel support arm is equipped with side shifting to facilitate the input of the shaft into the core.
