4 Maintenance of the anti-drop device system
4.1 Inspection of the guide rails
Inspect the guide rails to make sure they are not loose and check their overall technical condition.
4.2 Dismantling the fall arrestors
✔Disconnect the power supply to the door system!
1. Separate the cover strip from the guide rail.
2. Remove the wiring from the wire holder.
3. Separate the two fall arrestors from the door panel.
4. Remove the fall arrestors with locking devices through the openings in the lower part of the guide rail.
4.3 Inspection and maintenance of the fall arrestors
Inspect the fall arrestors and the locking devices as follows:
1. Check that the locking device moves freely and that the spring is functioning.
2. Clean the sliding surfaces of the safety rails.
3. Inspect the plastic sliding pieces on the safety rails as well as the current collector. Replace these
parts if needed.
4. Check that all connecting pieces are tight.
5. Clean the fall arrestor locking device if necessary and make sure the locking device works easily by
using a chain / bearing lubricant in the form of a spray. Under no circumstances should you use
greases, thick oils or cleaning sprays with solvents for this.
