Lifta med liften
Examensarbete om släpliftar
This degree project has been carried out by Carolina Rapp and Jenny Tauson, students at Innovation and Design Engineer program at the Faculty of Technology and science at Karlstad University. The project was carried during Spring of 2009 and took 15 weeks of full time work. Doppelmayr/Garaventa Group is an Austria/Switzerland corporate group and its associated company Doppelmayr Scandinavia lies in Sunne, Sweden. Doppelmayr/Garaventa Group is the world quality and technology leader in ropeway engineering. The degree project goal was to develop a new shaping of a surface lift. There are two kinds of surface lifts, platter and T-bars. The two kinds of surface lifts have some variation in design but only minor differences. The project focused solely on the part from wire down to the platter or T-bar. The design had to meet some specific requirements such as not exhume too much wind, fit on existing construction and low weight. It should also be unambiguous, understandable to the users, reliable, safe and ergonomic. To design a new surface lift that could manage the array of goals an extensive research was carried out. To understand and see what problems accure when riding on a surface lift, observations at ski resorts at Ski Sunne and Branäs in Sweden was conducted. Also questionnaire was made and sent out to skier to further investigate design flaws in current design. The extensive research and the observations helped the students when the creative phase began. One concept was chosen on the basis of the delimitations. The result was an adjustable T-bar that satisfies the practice needs of better comfort when he/she rides with another person of other length. The result from this project was shown in a full scale model, 3D-generated animations, sketches and an academic report. The project was shown in an exhibition at the yearly degree exhibition at Karlstad University. The 5 of June a presentation was made at Doppelmayr Scandinavia.
