Hydraulic elevator is an elevator solution used in buildings without a machine room, with low traffic density and with certain travel distances. Instead of a machine room, a suitable floor where the hydraulic unit will be mounted is sufficient. These elevators can be used for many purposes according to the need such as carrying people, freight, vehicles as well as as a hydraulic movement system in lifting vehicles designed as load platforms in areas e.g. stores, warehouses or factories. As the name suggests, hydraulic elevators provide car movement by means of a piston using hydraulic oil pressure. While the car’s own weight is used for the downward movement of the elevator car, hydraulic oil pressure is used for the upward movement of the car.
