Travel Measurement - Nussbaum POWER LIFT HL 2.60 SST DG Manuel D'exploitation

•
Place the vehicle to the desired work position or lower it to the lowest position. Push
operating element. The lift raises briefly (unlocking the safety cylinder) before the actual
lowering process starts.
•
Before reaching the lowest position the lift stops the lowering process for safety reasons (CE
stop = min. 120 mm before hazard).
After a recheck of the hazardous area, push the "Lower" button again. During lowering to the
lowest position an acoustic warning signal can be heard.
•
The lowering process must be continuously observed.
•
Once the fixture has reached the detectable lowest position, swivel the lifting arm outwards.

5.3 Travel measurement

To measure the travel of the threaded spindle, a Hall sensor is attached to the hydraulic
cylinders which counts the external ring in magnetised increments. These increments are
transmitted and compared on the computer control system (lean controller). An uneven lift
rail is balanced to the same height during a lifting or lowering movement. The current height
position of the lift can be read off from the display.
•
The computer control system monitors the entire process of the lift during "lifting" and
"lowering".
•
In normal operation the lift lowers at a speed of 0.05 metres per second. If the speed
increases, e.g. due to a defect in the hydraulic system, the computer control system detects
this problem and removes hydraulic supply to the unlocking cylinders. The interactive safety
system is activated and the lift remains in place.
