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

Shorteners (cromox® CVE) and sub-assemblies with shortener (cromox® CVK) allow the chain length or the length of a chain suspension to be adjusted quickly and easily on site – with millimetre precision. With little effort, the length of the chain slings can be adjusted with a chain shortener exactly as required for the respective application. The cromox® shorteners and sub-assemblies with shortener are made of stainless steel. This special steel is also called inox steel (from the French "inoxydable", meaning "non-corroding" or "rust-free"). The shortening hooks from Ketten Wälder GmbH have special durability and functional design. Naturally, the entire combination of shortener, chain slings and load-bearing chain links is tested for fatigue strength in our own Lloyd's Register-certified test laboratory as standard.

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.

Our special design prevents incorrect use

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.
 


FAQs

What are shorteners?

Shorteners in chain slings refer to components that are used to adjust the length of a chain sling. They are an important component in lifting technology to lift, move or secure loads safely and efficiently. A common shortening method is the chain shortener or shortening hook.

Where are shorteners for slings used?

Shorteners for slings and chain suspensions are used in various industries, including construction, logistics, mechanical engineering, and heavy industry. They are used to safely lift, move, or secure loads. They can be attached to cranes, hoists, or other equipment. It is important that the shortenings for slings are properly maintained and used to ensure safety.

What is the difference between shorteners and sub-assemblies with shorteners for chain slings?

Shorteners and sub-assemblies with shorteners for chain slings differ mainly in their design and application. A shortening is a single element that is used to adjust the length of a chain sling. A sub-assembly with shortener, on the other hand, is a combination of several shorteners that are used together to shorten chain slings (1-leg to 4-leg) to a certain length. The choice between shortening and sub-assemblies with shortener depends on the specific application and the user's requirements.

What are the advantages of shorteners for stainless steel chain slings?

Shorteners made of stainless steel are highly resistant to corrosion, which basically extends their service life and reduces their maintenance.

Stainless steel shorteners for chain slings offer several advantages. Firstly, they improve the overall strength and durability of the chain as they distribute the pressure over several links instead of concentrating it on a single link. Secondly, shortening enables more flexible handling and adaptation of the chain to different load sizes and shapes. Thirdly, they increase safety as they prevent the load from slipping or coming loose.

Sub-assemblies with shorteners – always the right length for efficiency and safety

The functional design and high load-bearing capacity make the cromox® shorteners made of stainless steel (inox) an indispensable tool for individually shortening chain suspensions for different applications - for greater efficiency and safety in your work processes.
