High Performance Wire Ropes Purchasing Recommendations


Based on many years of experience, resulting from close co-operation with leading crane manufacturers and customers using high-performance wire ropes, the following points should be considered when selecting a wire rope:

ALWAYS COMPARE APPLES WITH APPLES

Especially consider rope characteristics like breaking force, galvanization, plasticized steel core, expected lifetime and general quality factors which influence the rope performance.

CONSIDER THE MINIMUM BREAKING FORCE AS THE KEY SELECTION CRITERION

The minimum breaking force of a rope has to reach the level specified for a special crane as shown in the crane specification document. The use of a rope with less than the specified minimum breaking force is not allowed and may have serious consequences!

LEFT OR RIGHT LAY

The lay of a rope is crucial for the performance and the lifetime of a wire rope. The correct lay can also be found in the crane specification document. If you are not sure which lay is needed, you can also contact our technical experts.

LANG’S LAY OR ORDINARY LAY

Ordinary lay normally can be used for most applications. To allow the use of a lang’s lay rope, this must be specified in the crane specification document. Ropes in lang’s lay can reach a longer service life under certain circumstances. Lang ́s lay ropes must not be used in single
layer spooling and/or just on plastic sheaves.

CHECK CROSS REFERENCE

TEUFELBERGER can offer alternative special wire ropes for most rope types available on the market. To select a proper rope type, please specify the original rope type. Our rope experts will then select a rope that will reach the performance of the mentioned rope in any case.

CHECK METRICS (SIZE CONVERSION)

Be careful when converting the imperial into metric size, especially in case you require e.g. a 1″ rope. We offer tailor made ropes in imperial sizes.

USE OF GALVANIZED ROPES

Galvanized ropes can be used in any case and can always replace ungalvanized (bright) ropes.
The opposite way – replacing galvanized with ungalvanized ropes – is not recommended and may even be dangerous under certain circumstances, as the rope loses the positive effect of galvanization (higher corrosion resistance leading to a longer service life, especially in maritime environments).

CHECK ENVIRONMENTAL CONDITIONS

Factors like humidity, salt water, dust & dirt require a special protection of the inner core.
Therefore, a plasticized steel core is a major merit in relation to service & overall lifetime.

END TERMINATION

Please check which kind of end termination, if any, is necessary for a specific rope. This information has to be provided when placing an order. Please consider loss of efficiency for certain end terminations.

CERTIFICATES

Please check and specify when placing an order, which certificates are required.
TEUFELBERGER provides ABS, DNV, LRS, GL etc.
