13 Service
13.1 Wire rope
Wire ropes have to be exchanged by new, original wire ropes if they show corrosion, fracture or if they are
worn.
Checks:
Fastening screws must be checked before commissioning and at least every 3 months, - tighten them if
necessary.
Kind and number of broken threads.
Position of the broken threads
Timing sequence of occurrence of breaks.
Reduction of the wire rope diameter.
Corrosion
Abrasion
Deformation
Heat influence
Operation time
Wire rope fastening
CAUTION!
The wire rope must be replaced immediately should even one strand be broken.
13.2 Gear
quarterly: lubricate the worm gear wheel and the worm gear shaft
Recommended lubricant: grease, FUCHS Renolit FEP 2, or similar
13.3 Gear spring pressure brake
During the check, brake lining wear is verified. The brake linings must be replaced when the wear limit is
already reached at one position of the lining, - as this can be the case when wear of the linings is irregular.
CAUTION!
The brake linings must be free from fracture. Avoid oil, grease, dirt and humidity on the brake linings as this
increases wear.
