Hydraulic elevator
Hydraulic elevators are almost the safest type of elevators. The reason for this is due to the nature of the hydraulic jack system, which practically does not fall in hydraulic lifts. Of course, the same issue causes hydraulic elevators to have limitations, including speed and acceleration limitations, but in general, hydraulic elevators have a smoother and smoother movement than traction elevators.
Those elevators that are operated by oil pressure are called Jacky elevators or hydraulic elevators. In the domestic hydraulic elevator, the power unit and jack are responsible for providing the driving force. These elevators have simple and advanced types, whose simple examples consist of pistons and cylinders. These two pieces are installed exactly under the elevator cabin. After the engine rotates, the oil from inside the tank is pumped by the pump towards the elevator cylinder, and after its capacity is filled, the pressurized oil moves them up due to the force it exerts on the cabin and piston.
In general, the hydraulic lift is under the influence of the hydraulic jack and is moved by it. Of course, before the hydraulic jack, this liquid or oil is under pressure, which causes the lift cabin to rise. The word hydraulic means power generation, transmission and transformation by the same pressurized liquid. It is customary to use hydraulic elevators in many construction projects in Iran and around the world. Because the engine, pump, etc. are placed inside the machine room, such elevators do not need to install the engine room in the upper part of the shaft. Experts and experts believe that the hydraulic elevator is one of the safest examples and it is almost impossible to fall. Because it has a speed limit, but these elevators are not used in buildings that are very high. Due to the high quality of the movement of this sample of elevators and their smooth and smooth movement, you will not notice any vibration or noise when using the elevator.
