TEMPERATURE EFFECTS ON HOOK
BLOCKS
The Hook Block Working Load Limit (WLL) is valid between
60°C (140°F) and the low temperature limit given on the
hook block identification plate with normal lifting precautions.
Lifting above 75% of the Working Load Limit, at
temperatures between the service temperature given on the
identification plate and -40°C (-40°F), must be done at a slow
and steady rate to avoid stress spikes.
75% of the Working Load Limit must not be exceeded when
