Ensure that the hook assembly touches the ground in the lower hook position when determining the hook path/
lifting height. The chain hoists are provided with a hook path of 4 m, 5 m or 8 m as standard.
Secure the limit stop to the 5th link at the dead (unloaded) end of the chain.
● Follow the order of assembly. See also

To reduce the hook path, proceed as follows:
1. Position the hook as shown in the diagram.
2. Stop the chain hoist by actuating the emergency stop or the mains connection switch and secure it against
switching on again.
3. Remove the chain collector box

"Removing the chain collector box", Page 71.
4. Remove the limit stop on the chain collector box end.
5. Attach the limit stop directly behind the damping plate The unloaded chain fall behind the limit stop must con‐
sist of at least 5 chain links.
6. Place the chain in the collector box and re-connect it to the chain hoist.
7. Switch the chain hoist on and check adjustment of the lower hook position by moving the hook and run the
chain once through over entire adjusted hook path.
