For lifting equipment and lifting accessories, proper markings are not just a formality—they are a critical safety requirement. Mandatory markings identify capacity, origin, traceability, and regulatory compliance, ensuring the end-user can safely operate, inspect, and maintain the gear throughout its service life.
While exact details depend on regional standards, compliant lifting accessories typically require the following identification marks:
The Working Load Limit (WLL) or Safe Working Load (SWL), including specific angle ratings (e.g., 0–45°, 45–60°) for multi‑leg slings where applicable.
The manufacturer’s name or registered trademark, and often their address or a recognized country code to identify the origin.
A serial number, batch/ID code, or other unique mark that links the specific piece of equipment directly to its test certificates and technical file.
The year of manufacture (and sometimes the month). This is crucial to support proper inspection schedules and service life control.
Specific product designation details, such as the chain grade, sling type, or hook model.
Rated capacity for different configurations if the accessory has more than one mode of use (e.g., different hook positions).
For equipment within the scope of the Machinery Directive (EU) or the UK equivalent:
