cromox® stainless steel shorteners and sub-assemblies with shortener – easy to handle, safe to use

Our sub-assemblies with shortener CVK are characterised by their customised design for demanding lifting tasks, with a focus on quality and safety. Our products offer an efficient and flexible solution for a wide range of applications – made possible by Ketten Wälder GmbH's many years of expertise and innovation.


Top quality shorteners

At Ketten Wälder GmbH, we attach great importance to the quality of our products, including our shorteners, which are made from high-quality materials to ensure durability and maximum performance under all operating conditions. The cromox® shorteners are known for their robustness and reliability, making them a preferred choice in the lifting industry.



The cromox® shorteners stand for the highest safety standards and quality. They are specially designed to meet the demanding requirements of modern lifting operations by offering exceptional corrosion resistance and strength.

Fatigue strength of all stressed components determines the quality and safety of chain suspensions

Fatigue strength refers to the ability of a material to withstand repeated or continuous stress without fatigue or failure. As part of quality control, it is essential to test and verify the fatigue strength of the combination of shortener, chain, and load-bearing chain link.

Fatigue strength testing is carried out in our in-house Lloyd's Register certified test laboratory, where the component is subjected to repeated loading and unloading under controlled conditions to determine its ability to withstand fatigue and failure.

This involves measuring both the maximum load and the number of cycles the component can withstand before it fails. It is particularly important to test the fatigue strength of the combination of shortener, chain, and load-bearing chain link, as these components are often exposed to high and regular loads. Failure of these components can have serious consequences, especially in safety-critical applications.

In almost all industrial applications, it is essential to avoid misuse to ensure the safety and efficiency of the work process. The development of a chain shortener is no different. Here are some aspects that have been considered in the cromox® shortener to minimise the risk of misuse through special design:

1. Ergonomics: the chain shortener fits comfortably and securely in the hand. This prevents it from being accidentally dropped or mishandled.
2. Operating instructions: clear and easy-to-understand instructions in the operating manual enable the user to use the shortening tool correctly.
3. Material and construction: the choice of the right material and a robust construction make the chain shortener resistant. This prevents breakage or bending.
4. Adaptability: the well-thought-out design of the chain shortener reduces the likelihood of attempts to use it in a way for which it is not intended.
