CHAIN COLLECTORS
6.1 When supplied new the chain bucket will have been sized to suit the HOL of the hoist with spare capacity to allow for some bunching up of the
chain. The use of a chain collector can make the operation of the hoist more efficient preventing dangerous occurrences with the chain getting
caught or falling from the load being lifted as it mounts up on top of the load.
On hoists from 3 tonne to 15 tonne with a high HOL, galvanised chain collectors are used, with stainless steel buckets being used on ATEX hoists
and in areas of high corrosion.
On arrival at site the load chain should be removed from the chain collector either manually or by carefully running out of the hoist checking for
snagging. The chain should then be run back into the collector by the hoist checking there are no twists in the chain that the bottom hook is not
twisted through the chain fall on multi-fall blocks.
Hoists with long drops of chain and heavy loads in the chain collectors will require a secondary suspension point to hold the hoist in a vertical
position when unloaded. These may be as shown in section 1.8 or a secondary trolley on a runway beam.
If operating without a chain collector the slack end of the chain may catch or get caught on top of a load.
Always make sure the unloaded chain is running freely.
▪ Do not exceed the chain collector capacity.
▪ When the load chain is dry it may not run freely into the chain collector and over fill the collector, so the chain must be kept lubricated to
prevent it running out of the collector.
▪ Make sure the chain collector brackets have not been damaged during installation.
▪ Make sure the chain collector is free to move when the hoist is loaded and un-loaded.
▪ Make sure the bottom hook does not connect with the chain collector. Limit the lifting height of the bottom hook if necessary.
▪ For any assistance required on chain collectors please contact Red Rooster Lifting Ltd.
