Note: If the chain jams in the hoist and can no longer
be run out, the gearbox must be dismantled (see spare
parts list for “Gearbox”).
For dual chain hoists, when removing the old chain, an
assembly chain
1 is brought into position on the deflec-
tion sprocket of the bottom block by means of an open
chain link (see also
Removing and installing load
sleeve, bottom block, clamp and buffer section and
Removing and installing chain section).
Following replacement of the chain sprocket (see spare
parts list) an assembly chain
2 is run carefully
– with low air pressure – over the drive sprocket.
Fasten the new chain 5 to the assembly chain on the
drive sprocket by means of one or two open links 3 to
the idle chain side. The first chain link 4 must run
upright over the drive sprocket with the weld facing
outwards.
Switch the hoist to the “lower” rotational direction and
detach the assembly chain from the chain after it comes
out of the centre section.
For dual chain hoists the new chain, after it has been
aligned, is pulled over the deflection sprocket of the
bottom block using the assembly chain.
Note: If the chain link on the idle chain side is posi-
tioned incorrectly, it must be removed, the following
chain link will be positioned correctly.
Fastening of the chains and installation of the load
sleeve, clamp, buffer and buffer discs is carried out in
accordance with the
Removing and installing load
sleeve, bottom block, clamp and buffer section and
the Removing and installing chain section.
