This project aims to solve the problem of vertical transport of charges raised by a company with the standard UNE 58-132-91/6. The purpose of this project is the industrial design of a system of load handling by a bi-columned lifting device, tractioned by flat belts and steel cables from a transport level to a different level in order to connect two different assembly lines situated at different heights. The goal of this project is lifting a 780 Kg load at a 2.400 mm height. The project design ranges from the loading and unloading process, vertical transport, as well as the security mechanisms needed to ensure the correct operation. This project also includes the relevant economic study to determine the cost of the machine.
