●Be sure that the replacement chain is the exact size, grade and constructions
as the original chain. The new load chain must have an odd number links so
that both its end links have the same orientation. Destroy the old chain to
prevent its reuse.
When replacing load chain, check for wear on mating parts such as sprocket , ●
and replace parts if necessary.
Remove all chain components including bottom hook kit from the old chain ●
for reuse on new chain. Inspect and replace any damaged or worm parts.
Single fall operation - Using a C-link to attach the new chain to the old end ●
link on the no-load side. The new end link should be connected so the welded
portion to pass over the sprocket.
●Double fall operation – Feed the end link on the load side of the new chain
through the require chain components and idle sheave of load hook. Attach
the remaining chain components to the chain guide rail for the proper
locations.
Operate the hoist down to move the chain through the hoist body. Stop when ●
a sufficient amount of new chain is accumulated on the load side.
