The main purpose of this thesis is to develop an efficient and safe lifting device that can make the manufacturing process of electrical motors efficient but also make the work environment safer.

The process of the product development has been following steps taught at Universities around the world. These steps go from identifying the problem and making requirements to generating concepts and developing the most suitable one. In order to learn the operators’ opinions, a survey for choosing the right concept was applied at the production line that will use the lifting tool. A choice of concepts and a lifting tool was developed based on the survey results. This development includes calculations of forces, strength of materials simulations and detailed design of the different subfunctions. The result is a developed concept consisting of a physical prototype and drawings for manufacturing.
