Attachments must withstand a static proof load test (often 2 to 3 times the Working Load Limit, depending on the attachment type) without suffering permanent deformation.
Attachments must be designed to withstand the forces exerted during normal operation and accidental overloads. The standard mandates specific safety factors. For example, general mechanical structural components must be designed to resist a static force of at least without suffering permanent deformation, and 3 times the WLL without releasing the load. 2. Load Retention Requirements
Attachments must remain stable during operation. Spreader beams and lifting forks must be balanced so that the load does not tilt unexpectedly, which could cause it to slide off the attachment. The Importance of Compliance: Testing and Maintenance
The leap from the 2009 version to the 2020+A1:2025 version is significant. The latest standard provides enhanced safety requirements for a comprehensive list of attachments. These explicitly include:
