The platform transports payloads of up to 90 tonnes and is primarily used in the production of aeroplanes, wind turbines and rail vehicles, in which extremely bulky and heavy components have to be transported and positioned.. The lifting and stabilising of the load are taken care of by a lifting solution comprising worm gear screw jacks from Pfaff-silberblau, which have been developed by Columbus McKinnon expressly for this demanding application.

Four to eight electric, synchronised screw jacks are used per carriage. Each of them is equipped with a motor, anti-turn device, lift limitation by means of two initiators, integrated guide system and absolute encoder. The latter ensure the synchronisation of the worm gear screw jacks using the customer's control unit for a uniform lift of max. 250 mm also when the vehicle is in motion. Increased operating reliability is ensured by safety nuts, which also offer a facility for monitoring wear. Each and every one of the Pfaff-silberblau lifting screws supports a dynamic load of up to 100 kN or a static load of up to 150 kN.

For KUKA Robotics, it was essential to ensure that the lifting solution had an extremely low height and a compact design, as it had to be integrated into a very tight installation space in the heavy loads carriage. The compact worm gear screw jacks from Pfaff-silberblau easily satisfy this design requirement, for example by dispensing with external guides for the screw jack. This task is performed by a special guide pillar construction, which supports transverse and axial forces.
