Inclusive hydraulic aggregate
With this the hydraulic oil in the tank will be leaded over a gear pump, which is driven by the motor, to the
cylinder. Via a lowering valve the oil will be leaded back again into the tank.
10. Safety notches on main- and freewheel lift
This safety device prevents a lowering of the lift of more than 100 mm in case of any arbitrary defect. Electric
magnets are unlocking this device when lowering the lift.
11. Light barrier
