Hydraulic Systems

Lifting work is carried out by means of an electrically driven pump that delivers hydraulic fluid to a lifter that directly or indirectly affects the cabin. In these elevators, the downward movement is realized by the weight of the cabin. In hydraulic elevators, the engine room is generally located at the first stop level. There is an oil boiler and hydraulic machine (assembly), control panel and hoses through which the hydraulic fluid passes. Inside the elevator shaft the components are: cabin, counterweight (if any), cylinderpiston system, suspension device and buffers.

The pumped oil passes through the hydraulic machine, fulfilling certain conditions, and activates the cylinder through the pipes. The cylinder can be directly or indirectly connected to the cabinet. The cabin pushed by the cylinder is moved to the required floor with the received control.
