SEFIRO – „heavy duty roller with integrated tool changing system“
Greiner has recently delivered a SEFIRO in special design with a tool changing system to Schöller-Allibert GmbH in Schwerin and successfully integrated it into the manufacturing process at the customer.
Schöller Allibert invents, develops, designs and produces returnable transit packaging. Schöller-Allibert is active in the key sectors: agriculture, automotive, food, beverage, manufacturing and pooling. Schöller Allibert offers a comprehensive product range with standard and custom-made reusable packaging solutions. Among other things, Schöller Allibert is the market leader for foldable load carriers, beverage crates and trays, stacking containers as well as nest and stack trays, UN certified buckets, plastic pallets, transport trolleys and much more. Among other things, the hydrostatically driven Greiner vehicle is used to change impressive injection molding tools with weights of up to around 100 tons.
The demands placed on Greiner were manifold! Among other things the SEFIRO had to be operated emission-free and have a special tool changing system. A particular challenge was the transfer height of the tools of up to about 1,700 mm. The result was a SEFIRO with electric drive via lithium-ion batteries and a specially developed battery management control system. The hydraulic lift or axle compensation takes place by means of a double steering lift axle with a total of 630 mm lift. With this remarkable stroke, it is by no means inferior to the swinging arm principle with regard to low loading height and in terms of axle compensation. Rather, the Greiner axle suspension system is completely maintenance-free and movements of the platform when lifting or steering are thus excluded. This is an important safety aspect, especially in confined spaces. The detachable tool changing system is equipped with a roller conveyor mechanism, linear guides and a hydrostatic chain drive. With a disassembled tool changing system, the SEFIRO can be used for all other internal heavy duty transports for payloads over 100 tons. Among other things, the hydrostatically driven vehicle has steering programs such as normal, cross, diagonal and circular drive, an electronically-hydraulically controlled synchronisation lifting systems and numerous other features.
