Assembly Of The Hand Chain (Models with hand chain drive only)
To fit the hand chain position the slot on the outer edge of the hand chain wheel below the chain guide. Place any one link of the
endless hand chain vertically into the slot and turn the hand chain wheel until the link has passed the chain guides on both sides.
Attention: Do not twist the hand chain when fitting.
Geared trolleys are moved by pulling the hand chain.
Shortening or extending the hand chain (Models with hand chain drive only)
The length of the hand chain should be adjusted so that the distance to the floor is 500 - 1000 mm.
NOTE: For safety reasons, hand chain links may only be used once.
• Look for the non-welded link of the hand chain, bend to open and discard it.
• Shorten or extend the chain to the required length.
ATTENTION: Always remove or add an even number of chain links.
• Use a new link to close the loose chain ends by bending it (for extending the hand chain, two new chain links are required).
ATTENTION: Make sure that the hand chain does not turn during installation.
Installation of the chain stop
The chain hoist is delivered with a correctly installed chain end stop.
The chain end stop must be installed on the idle strand of the load chain so that there is at least one full free chain link under it.
Installation of the chain container
In the central part of the device, there are two brackets on the outlet side of the idle strand which serve as lifting points for the optional
chain container. Before installation, the load hook must be brought to the lowest possible position so that the chain end stop is moved
towards the housing. Finally, the delivered chain container with the long screw and self-locking nuts is fixed to the housing so that the
smaller chain container opening is positioned below the chain hoist housing.
ATTENTION: If the electric chain hoist is equipped with limit switches, a lug must be installed between the supports on the
chain hoist housing and the suspension lugs of the chain container.
The holding capacity of the chain container to be installed should never be smaller than the load chain length of the device on
which it is to be placed. Risk of chain break! This specification is applicable even if the device is used exclusively to lift loads
to lower heights.
NOTE: In multiple strand devices, the load chain length is a multiple of the possible lifting height!
Make sure that the two self-locking nuts are turned on the screws at least so wide that 1½ screw threads project over the nuts.
After installation, check the chain container for smooth working. To do so, lift the load hook over the entire load chain length so that the
bottom block triggers the optional limit switch or is moved against the chain hoist housing. During the lifting operation, check the smooth
entry of the load chain into the chain container.
If the chain hoist is equipped with a large chain container, the suspension must be provided with an additional tension relief. To do so, a
strap is to be fastened on the central part on the housing screw (motor side, against the fastening of the tension relief of the control
switch). To support the chain container, a short link chain can be placed between this strap and the chain container frame.
