cromox® Swivel Load Hooks for direct connection to chain CWHF

The requirements for swivel hooks for lifting and other lifting equipment are strictly defined and must meet certain safety and performance criteria as set out in DIN EN 1677 and other relevant standards. The DIN EN 1677 standard provides the foundation in Germany and Europe for the production and use of these lifting devices, outlining guidelines for mechanical features and surface quality and defining associated testing methods. Both manufacturers and users must adhere to these standards to ensure safety and efficiency. The swivel lifting hooks are designed according to these norms and suitable for the intended areas of application.

According to DGUV regulations, lifting equipment and accessories must be inspected and possibly replaced at specified intervals. The DIN EN 1677 standard establishes criteria for hooks with safety latches used for installing lifting chains, ropes, and straps. Annual inspections of lifting devices and their accessories with visual checks are required by DGUV guidelines. Moreover, every three years, crack inspections and load tests must be conducted. Post-production checks are carried out in the in-house laboratory of Ketten-Wälder.

The Duplex stainless steel AISI 318LN is known for its exceptional corrosion resistance and mechanical strength. Its properties are enhanced by the addition of molybdenum to combat aggressive substances and temperature fluctuations. This steel, with the chemical designation X2CRNiMON22-5-3, is especially resistant and easy to weld due to its high nitrogen content.

The cromox® products exhibit an excellent balance between lightness and load capacity. High standards are applied to all cromox® stainless steels, especially in the field of lifting technology and related accessories. Each delivery includes the corresponding inspection certificates and certificates.
