Inspection of chain reeving in the bottom block
All units with two or more chain falls must be inspected before initial operation to ensure that
the load chain is not twisted or kinked. The chains of hoists with two or more falls may become
twisted if the bottom block is rolled over, for example.
When replacing the chain, make sure that the chain is reeved correctly. The chain weld must
face outwards.
