왘
Align the chain and fasten the end chain link to the
hoist body by means of the end chain link pin.
(Position of the weld must align with that of the
following links.)
In the case of the PROFI 20 TI
If the end chain link pin was pulled out completely,
the bottom block chain link and the end chain link of
the idle chain have to be aligned. (Position of the weld
must align with that of the following links.)
왘
Drive in a new roll pin to secure the end link pin.

Removal (see illus. page 50)
왘
In the case of operation with chain box, run the chain
out of the chain box and detach it from the hoist.
Note : In the case of hoists with chain box, the end
chain link of the idle chain 4 is not attached to
the hoist body.
왘
In the case of hoists without chain box, detach the
chain link of the idle chain (for double chain and
quadruple chain hoists, except for EH 20, also the
end link of the bottom block chain
1 ) from the chain
mount on the hoist body. Drive out the roll pin 2
and remove the end chain link pin 3 .
왘
Immediately fasten the end link of the bottom block
chain to the hoist body in order to prevent the chain
from becoming twisted.
왘
Drive out the roll pin 9 from the clamp 10 .
왘
Remove the clamp from the chain.
왘
Detach the buffer 11 and buffer discs 12 + 13 from
the chain. On version PROFI 20TI with chain box, it
must be ensured that the three additional run-on
elements remain on the chain (see spare parts list).
Assembly
In the case of operation with chain box:
왘
Push the buffer disc with edge (edge encloses buffer),
buffer and buffer disc without edge onto the chain.
왘
Insert the tenth chain link into the chain pocket of
the clamp (chain pocket away from hoist body,
pointed outwards).
왘
Drive in a new roll pin to secure the chain link in
the clamp.
왘
Attach the chain box.
In the case of operation without chain box:
왘
Align the chain link of the idle chain (for double
chain and quadruple hoists, except for EH 20, also
the end link of the bottom block chain) and fasten
to the hoist body by means of the end chain link
pin (position of the weld must align with that of
the following links).
왘
Drive in a new roll pin to secure the end chain
link pin.
AT T E N T I O N !
Do not twist the chain! The chain is sub-
jected to impermissible stresses if the chain
is twisted.
See also Check dimensions, page 55. If the chain of
the JDN Air Hoist displays one of the following features,
it must be replaced with a new one:
왘
Corrosion scars
왘
Bent or damaged chain links
왘
Chain drawn stiff
왘
Wear over 11 pitches (A
max
)
왘
Single pitch wear (B
max
)
왘
Elongation of a single link (D
max
)
Check the entire length of the chain.
Please observe the information contained in DIN 685,
part 5 when checking chains. For further instructions
see ISO 7592.
