Service and maintenance

7.1

Test chain

• Check all parts of the test chain regularly.
• Ensure the links and rollers are free to move on shafts.
• Replace broken or missing retaining pins.
• Ensure wire rope anchoring cables are not frayed or twisted.
• Ensure clips are tight on the cable.
• Lubricate the chain with light machine oil to prevent rusting and ensure safe and free
movement. Either submerge the chain in a oil bath, or spray with common lubricants or
rust prohibitor.
• Place a hood or cover over the storage reel to minimize negative effects of dirt or debris
falling onto the test chain.
Annual verification of the chain should be made against a known, certified platform with
scale and length to precision measurements. Recalculate with the following measurements:
Test chain mass (without shackles)
Length stretched, referenced from center of
first roll to center of last roll:
Roller Pitch (from technical data):
Weight of 1 link:
(Mass + weight of 2 links) / (Stretched length + Pitch) _____________________ lb/ft or kg/m
