1.4 THE FLUID
The hydraulic fluid is very important for an hydraulic lift
Especially in systems with medium or intensive traffic,choosing a good fluid increases the temperature range of
comfortable working and enhances the service life of the components.
When we choose the fluid we must take into account both the characteristics of the elevator
(temperature , power unit ventilation room, amount of trafic) and the characteristics of the fluid
(temperature-viscosity).In case of replacement,follow the local pollution.Waste should be placed in a
proper box to protect the environment.
