Columbus McKinnon Yale CPV Series Translated Operating Instructions page 35

The chain anchor is then joined to the hoist body. New pre-coated safety screws intended for one-time use only must be used here.
Torques for the fastening screws:
M5 = 8Nm / M6 = 10 Nm / M8 = 25 Nm
Hardened for working after approx. 60 minutes
Hardening time at ambient temperature approx. 24 hours.
6. Functional test
All units with two or more chain strands must be inspected before every operation for twisted or kinked chains. Chains on 2-strand units
may become twisted if the bottom block is rolled over. If a strand is twisted disconnect it from the hoist and re-thread it correctly. In
some cases it may be necessary to remove the last link.
7. Before initial operation lubricate the unloaded chain and test all hoist functions under a no-load condition.
Maintenance Load Hook
Check the load hook for deformation, damage, surface cracks, wear and signs of corrosion as required, but at least once a year. Actual
operating conditions may also dictate shorter inspection intervals. Hooks that are rejected during the check must be immediately
replaced with new ones. Welding on hooks, e.g. to compensate for wear is forbidden.
Hooks must be replaced when the mouth of the hook has opened more than 10% or when the nominal dimensions are reduced by 5%
as a result of wear. Nominal dimensions and wear limits are shown in the following table. If the limit values are exceeded, immediately
replace the components.
Maintenance Trolleys
In particular check following parts:
• Side plate: For cracks or deformation in particular around the areas of screwed connections.
• Trolley wheels: Visually check for cracks and wear on trolley wheel flanges. Grease the transmission.
• Crossbars: In particular around threaded areas for cracks.
• Fasteners: Check nuts, screws and locking devices for tightness.
