What is a 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, this 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.
The principles of the functioning of hydraulic elevators 🔻
* In the hydraulic lift, the oil under pressure transmits the power, in the upward movement, the electric motor turns the pump and the pump sends the oil under pressure from the tank into the jack.
* In the downward movement, the electric motor is off and in this case the weight of the cabin and accessories and the weight of the load inside the cabin causes the elevator to move downwards and as a result the oil returns to the tank without consuming energy. It is controlled by a set of valves, which are called electric valves, and the speed of the elevator is regulated by these valves from the moment of start to stop.
انی The benefits of hydraulic elevators 🔻
* No need for the engine room above the elevator shaft
* Increase safety and reduce the risk of the cabin falling (in the system directly from below)
* Easy service access to the engine room in case of emergency
* The possibility of increasing the space inside the elevator cabin and reducing the cost of the forged structure (in the system directly from below)
* The possibility of simpler design for cabins with more than one entrance
