Cranes for production and storage
Optimum material flow
The crane unit consists of two mechanically connected 16-tonne double-girder overhead travelling cranes, of which one is fitted with control elements. With a span dimension of 30 m, they travel over the entire length of the 120 m-long storage bay. All travel and lifting motions are controlled by frequency inverters, which provide for smooth starting and precise positioning of the load. For the retrieval operation, stacks of panels are placed by the crane on a chain conveyor, which connects the store with the neighbouring production bay.
MBN employs two Demag cranes in the production bay. Both crane units each consist of two EKKE single-girder overhead travelling cranes, of which one each is fitted with the control system. A link arrangement maintains the fixed hook centre distance of nine metres as required for operation of the vacuum spreaders. One crane lifts the top panel from the stack and transports it to one of the four production stations. The entire process takes only a few minutes, in which the crane has to ensure that the required product is replenished. For this reason, fast operating speeds are necessary in order to keep the production facilities continuously replenished.
