Removal
왘
Move the bottom block as close as possible to the
hoist body. Position the bottom block securely in
order to prevent the chain from unravelling un-
controllably causing the bottom block to fall.
왘
Remove the bottom block end chain link
1
from the
chain mount on the hoist body; drive out the roll pin
2
and remove the end chain link pin
3
for this
purpose. In the case of the PROFI 20TI the end chain
link
4
of the idle chain is released simultaneously or
only remove the end chain link pin far enough to
ensure that the end chain link of the idle chain is
not released from the hoist body.
In versions with chain box, the idle chain is not
attached to the hoist body.
Note
: For subsequent assembly, it is helpful to work
with three short assembly chains
5
which are fastened
by means of an open chain link
6
to the hoist chain
being pulled out during removal of the chain and are
pulled successively over the deflection sprocket of the
centre section and the bottom block. They remain there
until assembly is completed.
왘
Pull the chain from the deflection sprocket of the
centre section and from the bottom block.
The run-on elements
7
and
8
, as well as the buffer
9
and the buffer discs
10
are thereby pulled from the
chain. On version PROFI 20 TI with chain box, three
additional run-on elements are provided on the bottom
block (see spare parts list).
Assembly
왘
Push the buffer assembly (buffer
9
plus buffer discs
10
, edge encloses buffer) onto the chain. On version
PROFI 20 TI with chain box, a run-on element must be
pushed onto the chain before pushing on the buffer
assembly (see spare parts list for adjustment).
왘
Align the chain and fasten it to the assembly chain
in the bottom block by means of the open chain link.
왘
Pull the chain through the bottom block and detach
the assembly chain and the open chain link from
the chain.
왘
Push the run-on element
8
onto the chain.
On version PROFI 20 TI with chain box, an additional
run-on element must be pushed onto the chain (see
spare parts list for adjustment).
왘
Align the chain and pull through the centre section
by means of the assembly chain.
왘
Detach the assembly chain and the open chain link
from the chain.
왘
Push the run-on element
7
onto the chain.
On version PROFI 20 TI with chain box, an additional
run-on element must be pushed onto the chain (see
spare parts list for adjustment).
왘
Align the chain and pull through the bottom block
by means of the assembly chain.
왘
Detach the assembly chain and the open chain link
from the chain.
왘
If no assembly chains have been used, the end of the
chain must be inserted into both the bottom block
and the centre section and pulled through by turning
the deflection sprockets using an auxiliary tool.
