1.12 Safety Features
Dead Man's Type Control
The operator is required to hold the control in the engaged position to initiate and
maintain a particular operation.
Roll-off Protection
Once the runways are raised, the approach ramps rise and act as chocks.
Longitudinal Light Barriers as Pinch Point Protection (Option)
The outside edges of the runways are equipped with light barriers. Once the light
beam is interrupted, the lift stops immediately.
After the error has been corrected, the hazard point is always enabled first by raising
the lift.
CE Stop
The lift stops shortly before reaching bottom position. The lift can be lowered com-
pletely by pressing the LOWER button again. An audible signal sounds until the lift has
reached its lower end position.
Measuring System for Runway Synchronization
Synchronization is achieved through a magnetostrictive measuring system monitoring
the level difference between both runways. Once a preset level difference is exceeded,
the lift stops immediately.
Pressure Relief Valve
The working pressure of the hydraulic system is limited by the pressure relief valve.
Seat Valves
Positive-control seat valves at the hydraulic cylinders prevent sudden lowering
movements of the lift in the event of a rapid pressure drop in the hydraulic system,
e.g. due to line break.
Safety Latch
The safety latch prevents sudden lowering movements caused by a pressure drop in
the hydraulic system or cylinder leakage.
