cromox® stainless steel safety bow shackle CSSB

cromox® stainless steel products represent true “Made in Germany” quality, developed through long-term research by Ketten-Wälder. These lifting devices meet the high standards of DIN EN 13889, which specifies designs, sizes, dimensions, safety standards, and testing procedures for connectors. The testing procedures include load tests, impact toughness, and tests for strength and fatigue resistance with specified testing forces.

The in-house testing laboratory of cromox® is certified by Lloyd's Register. In this lab, all cromox® products undergo rigorous quality controls to ensure their performance even under the harshest conditions. The specific regulations for these tests are found in standards such as EN 12195, EN 14492, or the DGUV Regulation 100-500. All cromox® products are routinely delivered with a corresponding test certificate, which is required for many applications.

Bow shackles are indispensable in lifting and conveying technology. They serve as robust connections between loads and lifting devices, with a special design featuring a bent body with a pin guided through the ends to ensure a secure anchoring of the load. Regular inspections according to EN 12195, EN 14492, and DGUV Regulation 100-500 "Operation of Load Lifting Attachments in Lifting Equipment Operation" are mandatory for operators of such lifting systems to ensure the lasting reliability and safety of these critical connecting elements.

In Germany, such lifting operations must be carried out according to this DGUV rule and may only be performed by individuals specifically assigned and qualified to handle lifting accessories. Industries that frequently use these shackles include mechanical engineering, the maritime industry, the automotive industry, as well as the construction and energy sectors. These shackles are also essential for the food industry due to their food-safe surface, allowing use under hygienic conditions. In all these sectors, the bow shackles are valued for their reliability and safety in handling heavy loads.

Austenitic steel AISI 316L is distinguished by its excellent corrosion resistance and mechanical strength, making it ideal for demanding loads. The addition of approximately 2% molybdenum enhances its resistance to chloride corrosion, making it particularly resistant to acids and alkaline solutions.

With a lower carbon content compared to stainless steel AISI 316, AISI 316L also features good processability, including excellent weldability. Suitable for low temperatures, this polishable steel can theoretically be used at temperatures up to 550°C. In continuous operation, it remains resistant to intergranular corrosion due to its low carbon content. The cromox® stainless steel is designed to be perfectly suitable for the standard values of - 20° to + 200° C described in DIN EN 13889.
