Lightweight elevator : A portable elevator capable of climbing rooftops

Detta är en Kandidat-uppsats från KTH/Mekatronik; KTH/Mekatronik

Sammanfattning: The purpose of this project is to design and construct a portable lightweight elevator for transportation of goods to rooftops. The elevator should be easy to transport, assemble and disassemble, it should also be useful at various heights and for a wide range of roof inclinations. The elevator contains a railway consisting of four separable modules. A carriage rides the railway and is pulled to the top with a winch powered by a DC-motor. The carriage starts and stops using a Rocker switch and a Hall sensor that detects magnets placed at the end and beginning of the railway. After performing tests with the elevator the conclusion is that the elevator is practical to assemble and transport, but the carriage derails too easily when the railway has angular changes.
