Freight elevator:
This elevator was put into operation in 1900 and has continued to now. This amazing clip is part of the history of the elevator industry and related industries. In this elevator, the direction of movement is controlled by the pulley and the operator. The operator transmits the power transmission belts from the right-hand pulley to the left-hand pulley by pulling the tow wire connected to the pulley. This elevator was initially used with a steam engine but now has an electric motor. In the past, all control logics were implemented by mechanical components, but now these logics can be easily and unrestrictedly implemented in computer processors.
