Load chains not under tension
DANGER
Danger caused by a falling load!
– Make sure that the chain(s) does (do) not
become slack when lowering the load.
Slack chains can, for instance, result from:
• Resting the fork carriage or the load on the
racking.
• Fork carriage rollers blocking in the lift mast
due to contamination.
– If the fork carriage or the load comes to an
unexpected stop, lift the fork carriage until
the chains are under tension again and
lower the load at another suitable location.
– If the fork carriage rollers in the lift mast
become blocked due to contamination, lift
the fork carriage until the chains are under
tension again. Remove the contamination
before resuming work.
