Working loadcalculator

Break strength is not working load. Design factor, termination, bend radius and sling angle all sit between the two — this shows each one's contribution rather than hiding them behind a single number.

Design factor

General rigging and lifting

Termination

Correctly made, full bury · 100% efficiency

Bend radius (D/d)

Sling configuration

Safe working load

8,500lb

37.8 kN · 4 short ton

Minimum break strength: 42,500 lb
÷ design factor 5:1: 8,500 lb
× termination 100%: 8,500 lb
× bend factor 100%: 8,500 lb
