shank hooks

When hooks and components are produced in accordance with the DIN 15400 specification, you can rest assured that the manufacturer has met stringent production criteria to produce a high-quality product. DIN 15400 is the “Standard of Excellence” used in the heavy crane industry. Our heavy-duty crane hooks produced by our Stahlhammer Bommern GmbH (STB) business in Germany are designed to meet this standard.

Specification DIN 15400 was developed in the early 1940’s to provide requirements to manufacturers for the production and finishing of shank hooks. This specification not only gives guidance for hook production but also includes dimensional requirements for nuts and trunnions. The standard specifies requirements intended to ensure the reliability of forged hooks.

DIN 15400 offers guidance for capacity ratings of hooks, similar to CMAA, based on various component input of crane usage. This is known as drive groups in the specification.

DIN 15400 includes requirements for threading of crane hooks, nuts and cross pieces to ensure a quality product is produced.

DIN 15400 also includes guidance for markings, testing, heat treatment, surface conditions, dimensional accuracy and mechanical properties.

Good day Moses,
Latches are available for all sizes of hooks but are sold separately. The reason why the latches are sold separately is as follows: if latches are assembled on unmachined hooks, the latches could be destroyed during the machining process.
Thank you for reaching out to us.
