The UPL-300 is a fully electric wheelchair lift for trains. Many wheelchair lifts for trains exist on the market but the vast majority are driven by hydraulics. Electric drive prevents potential hydraulic fluid spills and negates the need for special disposal of the fluid. The aim of this project was to improve this lift because it struggled to compete on that market and no longer met industry standards. This project first identified which areas of the UPL-300 needed improving and then worked on two of these areas, the linear drive unit (LDU) which enables the lift to go up and down and the wall brace which connects the linear drive unit to the wall of a train car. The results were a design document for the wall brace and a new design for the LDU. The wall brace design document aimed to simplify and expedite the design process of the customer specific wall brace. The new LDU cut the cost for the lift significantly and fulfilled the requirements of modern standards. The design of the new LDU is easily scalable and has the potential to be used as a linear actuator in other products. The improvement analysis, together with the other work done in this project, laid a strong foundation for future work to improve the UPL-300 fully electric wheelchair lift for trains.
