The hydraulic pump driven by the motor conveys the hydraulic
medium into the space below the piston. This generates hydraulic
pressure that acts outwards via the piston and lifting rod.
The piston and lifting rod move backwards after the motor is switched
off either due to a force acting from the outside (brake weight, brake
spring) or due to the integrated reset spring. The lifting force that is
available to the user of the ELHY
difference between the generated hydraulic force and any external or
internal counterforce.
The lifting and lowering times depend on both the load and the
viscosity of the hydraulic medium, which is in turn affected by the
ambient and operating temperatures. In the versions with lifting,
lowering or throttle valves, the setting/resetting speed of the lifting rod
and therefore the lifting and lowering times can be adjusted infinitely
within a specific range.
If the piston is in the limit position (e.g. in continuous mode S1), the
motor's power consumption reduces due to hydraulic laws. This
prevents the ELHY
