Accident/Breakdown Procedure
The lifting chains need to be taken out of operation immediately in the event of an accident or unforeseen incident
– e.g. accidents, overheating, overloading, collisions, acid and chemical influences. In doing so, it must be ensured
that through the removal of the lifting chain the load and personnel are not harmed in the process, e.g. because the
load was set down in an instable manner, it could tip over. If deemed necessary, an additional chain can be mounted
before the damaged one is removed – the chain should then be given to a qualified person for evaluation.
Evaluation, Repair, Maintenance
The safety of the chain can be influenced during its natural work life; it is therefore vital that to maintain it in a good
state of use through periodic maintenance, evaluation and repair.
Maintenance: Lifting chains should also be cleaned, dried and safeguarded against corrosion, e.g. lightly oiled.
Especially accessories that have movable parts such as bolts or bearings need to be oiled to protect them from
E
corrosion, increased wear and seizing.
Inspection before initial use: Before using a lifting chain for the first time, the following points should be checked:
• The lifting chain corresponds to what was ordered
• The test certification and/or the declaration of compliance and conformity are present
• The CE-marking and load capacity on the lifting chain correspond to the details on the certification and
declarations
• Recording individual details of the product into a chain card index
• This manual is included with the lifting chain and that every employee reads and fully understands what has been
written
Inspection before every use: The chain should be checked to make sure it is in a good state before each and every
use by the operator. He should pay attention to obvious damages or signs of wear; if in doubt, or if the chain fits into
one of the below-mentioned "discard" categories, the chain should be taken out of operation immediately and given to
trained personnel for evaluation.
Evaluation: Evaluation of the lifting chain should take place after it has been cleaned – it must be free from oil,
dirt and rust. Painting is only admissible as far as an evaluation of the chain sling condition is possible. Methods
of cleaning that cause embrittlement of the material (pickling), overheating (burning), abrasion of material (sand
blasting) are not permitted; cracks or other defects should not be hidden.
Sufficient lighting during evaluation needs to be provided; the whole of the lifting chain should be inspected; if in
doubt, the chain should be sent back to the manufacturer for evaluation.
Inspection after an unforeseen incident: The lifting chain needs to be taken out of operation immediately and given
to trained personnel for evaluation in the event of an unforeseen incident – e.g. accidents, overheating, overloading,
collisions, acid and chemical influences.
Inspection carried out by trained personnel: Trained personnel should carry out periodic inspections based on the
national legal requirements; if not otherwise specified a minimum of every twelve months. This time frame should be
shortened for lifting chains in frequent use at maximum load capacity or under implementation-related limitations, in
the case of increased wear or corrosion. The inspection includes both visual and functional testing.
After long periods in storage, the lifting chain should be checked thoroughly by trained personnel before initial use
especially if the date for inspection has been exceeded or the product was stored incorrectly – see below.
Load Test: A load, visual and function test needs to be carried out by trained personnel at least every two years.
This time frame should be shortened for lifting chains in frequent use at maximum load capacity or under
implementation-related limitations. The load test should be carried out with 2 times the working load limit. It can
also be replaced by a crack detection test – e.g. by a magnetic crack test or a dye penetration method. In this case,
the chain sling must be checked throughout its length. Note: The interval of the load test may vary due to national
regulations.
"Discard categories": If the lifting chain falls into one or more of the below-stated categories, then it should be taken
out of operation immediately:
• Breakage
• Missing or illegible tag/marking
• Unrecognisable identification marking of components
