A linear lever concept: designed for an ergonomic usage

Abstract [en]

Kalmar Industries is a worldwide company with over 100 years of experience in lifting and transporting heavy loads with heavy lift trucks. The company intends to strengthen their leading position worldwide with a new generation of ergonomic and user friendly cabins. A central part in the cabin is the linear lever module that controls the aggregate. Linear levers can either be hydraulic or electrical, only the electrical system will be applied in the new design. Today’s electrical levers are not appreciated as much as the hydraulic levers because of the lack of “feeling” during use. The aim of this thesis work was to create design guidelines for Kalmar Industries and generate a module design with electrical levers that will satisfy the users’ expectations. Design guidelines for the linear lever module were created based on cognitive and physical ergonomic theories. A semi structured interview and observations were carried out and analyzed. Four concepts were generated based on the guidelines, user wishes and product restrictions. Two evaluations were performed and a final concept was generated. The final concept focuses on a comfortable and reliable use where the primary functions have a central position. A physical prototype evaluated by users or a computer aided ergonomic simulation is recommended as next steps in the development process. The final concept design stands up for Kalmar Industries demands and their user expectations: in situations where user opinions varied design guidelines were helpful. Its design is innovative and invites the operator to a comfortable day at work.
