Hydraulic lift is an elevator solution used in buildings with low traffic density and with certain travel distances. Instead of the engine room, a suitable floor on which the hydraulic unit is to be installed is sufficient. According to the needs of people, freight, can be used to transport vehicles; Hydraulic movement system is used for lifting vehicles designed as load platform in areas such as store, warehouse and factory.

Hydraulic elevators provide cabin movement by means of piston using hydraulic oil pressure. In the downward movement of the elevator car, the car's own weight is utilized, while the hydraulic oil pressure is used for the upward movement of the car. In hydraulic lift systems, the cab is lifted by a piston guided by the liquid installed in the cylinder. This cylinder is connected to the liquid pumping system and is generally used as petroleum or other incompressible liquids. The hydraulic lift system has three main parts: a reservoir with liquid, a pump powered by an electric motor, and a valve between the cylinder and the fluid reservoir.

The fluid is pushed from the reservoir to the cylinder by the pump. When the valve is opened, the fluid under pressure returns to the tank. When the valve is closed, the fluid under pressure enters the cylinder and is collected there. In this case, the piston is pushed up and the elevator car rises. When the cabinet reaches the desired floor, the control system sends signals to the electric motor to shut down the pump. To lower the cab, this time the control system sends signals to the valve in that direction. The valve opens and the fluid accumulated in the cylinder returns to the tank. In this way, the cabin begins to descend.

Elevators, which do not carry out the necessary inspections and controls, are in a position to threaten the safety of people and property at any time. For this reason, maintenance and inspections should be carried out annually under the regulation. The Elevator Maintenance and Operation Regulation sets out the rules to be followed for the operation, maintenance, periodic inspections, warranty conditions and after-sales services of elevators.

In addition to the Elevator Maintenance and Operation Regulation, the Regulation on Health and Safety in the Use of Work Equipment also describes the conditions that must be complied with in terms of health and safety during the use of elevators. Accordingly, man and load-bearing elevators should be checked at least once a year unless another time is stipulated in the relevant standards.

The Annex to the Regulation on Maintenance, Repair and Periodic Inspections (Annex 3) has included elevators in the group of lifting and transmitting vehicles. Inspections and inspections must be carried out by mechanical engineers, machine technicians or high technicians. Persons who are authorized in the electrical parts of the elevators should also participate in these control works.
