Section 8 - Inspecting Cables for Signs of Excess Wear
How Often to Look:
•
Regardless how infrequently the Ropewalker is used, a thorough inspection should be
carried out annually at a minimum.
•
Frequency of inspections depends on how often the Ropewalker is used.
•
Equipment which is used frequently should be inspected approximately every 300 uses.
Where to Look:
•
Stress points most likely to suffer from excess wear are along attachment points.
•
Wear and damage can occur at any point along the wire lift line. The entire length
should be checked.
•
All lift line terminations
How to Look:
•
While wearing tough work gloves, wrap a cotton cloth gently around the wire lift line
and either operate the Ropewalker or manually work hands along the cables.
•
If there are snags or other damage developing, the cotton cloth will catch on them.
Visually inspect the wire lift line for signs of abrasion, corrosion, and discoloration.
What to Look For:
•
Lift lines must be inspected periodically for signs of wear.
•
Visually inspect the wire rope, looking for broken or flat wires, corrosion, excessive
wear or signs of chemical etching.
•
Ensure the wire lift line is not rubbing against anything at any point along the run, and
that it is free of dirt and grease.
•
Cable thimbles and loops should continue to hold their shape and not be elongated.
Section 9 - Cable Arresters
Operation of the Self-Retracting Device
1. Inspect the Self-Retracting Device before operating the Ropewalker. Do not use if inspection shows damage or any malfunction.
2. Follow the instructions contained in this manual and on the labels. Failure to follow instructions may result in serious injury or death.
3. A certain amount of tension must remain on the cable at all times to ensure proper operation of the internal brake.
CAUTION: Do not allow the cable to become slack. If the cable becomes slack, remove the Ropewalker from service for inspection.
Locking Mechanism
1. The Self-Retracting Device utilizes an acceleration based locking mechanism.
2. The locking function requires a certain payout rate during a fall event to function correctly.
3. A clear path is required to assure positive locking of the Self-Retracting Device.
4. Ensure the lock is functioning properly:
Pull the cable out a short distance and tug sharply. The cable must lock.
If it fails to lock, remove Ropewalker from service immediately.
Fall Arrest Impact Indicator
CAUTION:
DO NOT allow one Self-Retracting Device cable to become tangled or twisted during use.
DO NOT clamp, knot, or prevent the cable from retracting or being taut.
DO NOT lengthen the Self-Retracting device by connecting a cable or similar component.
After a Fall
Remove from service any equipment that has been subjected to fall arrest forces or that exhibits damage consistent with such forces.
(cable clamps, thimbles, loops, Nico sleeves)
should be inspected.
