ACCESSORIES
CHAIN BOX
In various application situations, a chain box enhances operational
safety, e.g. if a chain that is hanging down could become caught up
with the load.
JDN chain boxes are available in various sizes, corresponding to
the chain lengths.
ATTENTION!
Do not exceed the permissible filling capacity.
Danger of chain falling.
ATTENTION!
Loads must not be moved against the chain box
during lifting. Please contact us, if required.
A clamp must be attached in the 6
th
chain link of the unloaded chain
end so that a length of chain remains in the chain box when the
bottom load hook position is reached. Thus, the chain cannot run
next to the chain box during subsequent lifting (see Removing and
installing chain page 56).
Depending on the ratio of the size of the hoist (without running gear)
and the chain box, the chain box may have to be stabilised by the
customer due to an acceptable vertical hoist position.
This is facilitated by a suspension point on the rear of the box. We
will be happy to answer any questions on this matter.
Modifications may only be made to the chain box on agreement with
J.D. Neuhaus GmbH & Co. KG.
ATTENTION!
Never allow the chain to pile up in the chain box.
The chain must only enter the container via the
chain drive. If it falls out of the container, e.g. during
transportation, it must be run out completely on the
load hook side and then run back into the container
via the chain drive, in the air hoist operating
position.
After installing the chain box, lower the load hook to the
bottom position once.
Then activate the lifting movement and run the complete
chain into the chain box.
DANGER!
When operated with a chain box, lubrication of the
chain is particularly important in order to prevent it
from piling up and falling out of the box. Do not
install longer chains when changing chains.
Furthermore, hazards arise due to rusty chains
when operating with chain boxes, as the chain can
form a heap and fall over the edge of the container
rim. In addition, rusty chains are subject to extreme
wear.
If the hoist has been transported with the chain in the chain box, the
chain box must be emptied manually before initial operation (if
necessary, remove the chain box from the hoist). The entire chain
must then be allowed to run to the load side and, subsequently, be
driven back into the chain box. The hoist must be kept in a hanging
position during this procedure. This process will ensure that the
chain does not lock when loads are being lowered.
