Do not knot the load chain or splice/connect it by using pins, bolts, screw drivers or similar. Do not repair load chains installed
in the hoist. Protect load chain from weld spatter or other damaging contaminants.
Only fit load chains which have been approved by the manufacturer. Non-compliance with this specification will render the
legal warranty or guarantee void with immediate effect. See Chapter 7 Maintenance for more information on maintenance of
the load chain.
Hooks
Do not remove the safety latches from top and/or bottom load hooks unless you are replacing them with new latches.
Never mark or hard stamp hooks or any other load bearing parts.
The hook opening will elongate with overloads and incorrect hooking. When the hook measurements have changed beyond
the permissible discard limits shown in the table in Chapter 12 Technical Data/Hooks, it is dangerously deformed and must be
replaced immediately.
Dye penetrant, magnetic particle inspections (MPI) or other suitable crack detecting inspections should be performed on
hooks at least once a year, if external conditions indicate there has been unusual usage.
Newer models of the SS11 and PROLH are fitted with the patent pending Tiger “EZ check” 3 point marking system. With this
system a quick check that the A and B measurements are the same (as shown in the diagram below) will indicate if the hooks
have stretched If A
≦
B the hook is fine; If A>B the hook needs to be replaced:
