Sammanfattning: GBD-Storage Systems is a company that provides the industries with products for efficient storage.The company produces pallet racks and accessories like cassettes and extending units. The companyhas also supplied tire racks for a number of tire companies. The company's CEO Gunnar Berglund hasfor some time had an idea to improve the working situation of the workers on tire firms by allowingthe wheels to be handled by a counterbalance truck. The current situation poses numerous heavy liftswhen the tires are handled and therefore is hurting the workers.This thesis has been aiming at helping the GBD-Storage Systems by developing a concept of howan accessory to counterbalanced trucks can be designed to cope with the wheels. This concept willthen be produced as prototype by the company. The initial conditions were to create an accessory thatcan be run with the hydraulics of the forklift truck. The gadget would be dimensioned in accordancewith an EU-pallet to allow use on most counterbalance trucks. By following the product developmentprocess as taught at Mälardalen University the works has progressed well.The result is an accessory of 800 x 800 mm, made up of a framework of square tubes. Mounted onthis were two linear units that allow lateral motion. On top of the linear units there is one mountedslewing ring bearing and on that two telescopic rails. On the telescopic rails a plate is mounted wherethe wheels are placed. Between telescopic rails and plate are two double-acting hydraulic cylinderswhich handle loading and unloading of the tire places. These cylinders are connected to the forklifthydraulics through the connections to the forks side shifting. The gadget can be managed with thecontrols that are already in the truck.The project has progressed without major problems and the results are satisfying. In the finalconcept was though the choice of loading direction handled manually. This is recommended to bechanged in a finished product.
