8.5.6.2 Hook safety catch
If the hook safety catch has to be replaced, turn the nut on the bolt until at least two turns of the thread can be
seen on the other side of the nut. The bolted connection must only be tightened enough to allow the hook safety
catch to move freely.
8.5.6.3 Checking the return sprocket
The return sprocket must be checked every month to ensure that it turns easily. To do this, any load bars attach‐
ed to the bottom block have to be removed.
Check to ensure the bottom blocks moves easily during lifting and lowering operations. Abrupt movements of the
bottom block indicate wear.
We recommend that the return sprocket should be replaced every second time the chain is replaced.
