General Safety Notes for Lashing Chains
Instructions for safe handling and avoidance of danger.
This user information/manufacturer's declaration must be kept for the entire utilisation time.
We hereby declare (supported by the certification DIN EN ISO 9001 – 2008) that the following specification
is based on the corresponding safety and health requirements of the EC guidelines. Any changes of the
product that have not been agreed upon before with Ketten Wälder make this specification invalid.
The specification will also become invalid if the product has not been inspected in regular intervals.
The product shall only be used if:
•The lashing forces are known and they do not exceed the maximum admissible lashing forces
indicated on the tag, with possible shock and/or cyclic loads being taken into account.
•It can be made sure that the stress resulting from the lashing forces applied acts only axially to the
spindle of the ratchet tensioner, i.e. only freely hanging in pulling direction. Any bending stress has
to be ruled out as it may lead to damage.
•A visual and functional inspection is to be performed prior to repeated use. It has to be made sure that
the spindles move easily within the travel range and that no deformation, cracks or other signs of
damage are visually noticeable. In the event of apparent damage, the device must not be used any more!
•Lashing chains and ratchet tensioners must not be used for lifting loads.
•The size of the appropriate lashing chain and ratchet tensioner(s) to be used for the force to be
taken up is to be chosen in dependence of the lashing forces required for that purpose and the
type of application. Use long-link chains only for logs!
•The ratchet tensioner must be lashed with the manual lever (approx. 50 kg) and not with the
help of a tube extension or similar.
Right way Wrong way
•For safety reasons, the travel range of the spindles is limited according to size.
Maximum tensioning travel distances are:
u 75 mm for size 6 (1/4”) with 6 mm chain
u 150 mm for size 8 (5/16”) with 8 mm chain
u 150 mm for size 10 (3/8”) with 10 mm chain
u 130 mm for size 13 (1/2”) with 13 mm chain
These limits are only reached if both spindles are extended to the stop.
Caution! Exceeding the range of travel by using force will damage the locking
mechanism as well as the thread, rendering the ratchet tensioner uselers.
User Information
•The selected lashing chains must be both strong and long enough to suit the intended
application, and they must also have the right length with respect to the method of lashing
for which they are going to be used. The standard EN 12195 - 1: 2008 serves as a basis.
•Due to differences in behaviour it is not admissible to use different types of lashing equipment
(e.g. lashing chains and lashing straps) for lashing down one and the same cargo.
•Before unfastening, it has to be made sure that the load will stand safely and that it does not shift.
•If safety catches are available they have to be used.
•In order to guarantee safe functioning and to reduce wear and tear, the mechanically moveable parts
of the ratchet tensioners are to be lubricated with grease or oil in dependence of the frequency of use.
•Correct application ensures the prevention of physical damage to oneself and other persons.
Faulty application may lead to serious injuries.
•Beware of low hanging overhead cables while loading and unloading.
•Relevant applicable regulations, rules and directives for the securing of loads are to be observed.
•Damage due to sharp edges or the like have to be excluded by appropriate protective measures.
•Ratchet tensioners are to be positioned in such a way that proper footing and balance
can be ensured during operation (the operator is NOT to stand on the cargo!).
•It is not admissible to use lashing chains that have been knotted together or joined with bolts or screws.
•Operating instructions are to be kept accessible for all operators and are to be observed.
•Danger when loosening the lashing chains.
•Danger of possible blowback by the manual lever.
