Safety & Standards
What is the safety factor for your polyester round slings? keyboard_arrow_down
Our polyester round slings are manufactured with a strict 7:1 safety factor (SF) in
accordance with EN 1492-2 standards. For US markets, we also adhere to ASME B30.9
guidelines which typically mandate a 5:1 design factor. Always refer to the specific
tag on the sling.
How often should lifting slings be inspected? keyboard_arrow_down
Inspections should occur at three intervals:
- Initial: Before first use.
- Frequent: Before each shift or lift by the user.
- Periodic: A complete inspection by a designated person at least every 12 months, or more frequently based on severity of service.
