The graduation essay has been carried out in co-operation with Kalmar Industries in Lidhult, Sweden. The purpose of our essay was to develop a complete construction solution on a hoist that could lift a laying wheel, lift it up and then turn it 90 degrees. After that the wheel shall be placed in a special holder. The background of the essay is a record of reports of damage wheels when they been incorrect lifted with a forklift. The hoist shall be used together with the same forklifts that manage the wheels today. Together with our instructor at Kalmar Industries we developed a requirement specification and from that we got free hands. However this was not the main task from the beginning, then a simular hoist should be develop but used directly in the assembly workshop without using a forklift. We started to find principle solutions that later was evaluated against the requirement specification. The best proposals were analyzed by hand and in Catia V5: s FEM-module. After a couple of bettering proposal it resulted in a tenable solution. Drawings, component specification and a risk analyze was made to finally have a complete solution. Kalmar Industries decided to order material and manufacture the construction. The benefits with our construction compared to the daily solution are decreased risk of person injury, equipment-, and wheel damage. Our essay resulted in a complete construction ready to use.
