The task of both cranes is the storage and supply for the laser cutting unit of plates of up to 6m long as well as clearing the laser unit. The standard fork hanger with hydraulically separation-adjustable crane forks is used to handle the plates. The hanger can be tilted hydraulically in order to best pick up the plate. The plates are stored in cantilever shelves. The stacking crane has the advantage that no rail is required on the floor and the floor can be used to store the finished products.
A vacuum hanger with two crane forks is used to handle the completed cut plates. The current supply and the control device for the vacuum hanger is already fitted to the stacking crane’s fork hanger. The hanger only needs to be connected. The Voith telescopic stacker beam proves itself to be of an extremely robust design. The telescopic beam is controlled by an adjustable slideway. The advantage over a roller guide is that the slideway can accept significantly greater force and there is only one point of wear on the guide pads which can be compensated by simply adjusting the guide pads. As the slideways can be found on all sides of the stacker beam, the telescopic beam can be stressed in all directions.
This means that the telescopic mast cannot be over-stressed where the fork hanger is picked up off-centre along its length. This is often causes problems with roller guides on the telescopic beam.
