Estimated SWL0.51 t
Implied minimum breaking load2.56 t
Important Notes
- Rule-of-thumb estimate (SWL ≈ D²/500 tonnes) for general guidance only; rope construction, termination, reeving, angle, wear and environment are not modelled.
- Always use the manufacturer's rated capacity and a qualified rigger.
