hydraulic elevator system:

Hydraulic elevator systems operate using pumps that can transfer incompressible liquids, such as oil, from a fluid container to a cylinder through an open valve. The fluid accumulates in the cylinder and pushes up the piston located inside, so that the elevator rises to the corresponding floor.

If the valve is closed, the fluid will not be able to return to the liquid storage tank, and the fluid will stay in the cylinder, causing the elevator to lift. When the signal is sent to the control system, the elevator will descend, at which time the valve will open and allow fluid to flow back to the reservoir, thereby reducing the weight of the elevator car.

Generally speaking, the hydraulic system is simple to operate, and the lifting and lowering effects are very good, but the energy efficiency of the elevator using the hydraulic system is low, and the use of this system requires the drilling of a cylinder shaft as deep as the system height. If the building is fifteen meters high, the cylinder must be about fourteen meters deep below the system. Because of its shortcomings, mechanical elevator systems have emerged.

Mechanical elevator system:

The mechanical elevator system is also called the rope elevator system. At present, this system has been used in most modern construction projects.

The hydraulic elevator system uses pressurized liquid to push the car to the hoistway, while the mechanical elevator system uses an electric motor to move the elevator car from one floor to another using ropes and counterweights. The rope is connected to the pulley and the motor, which can move the rope up and down. One side of the rope is connected to the elevator car, and the other side is connected to a counterweight suspended on the other side of the hoistway. The counterweight saves energy by reducing the effort required to lift the elevator. The car and counterweight are placed on the track in the elevator shaft, and they need to be kept in place when the system is running.
