Chain sling safety factor • Shock load chain slings . ” Standard Gunnebo Lifting Work Load Limits (WLL) are based on a 4/1 design factor. Rated Load For Grade 100 Alloy Steel Chain Slings Vertical And Bridle Hitches; Nominal Chain Size Single Leg Slings Double Leg Bridle Slings Single Basket Slings Triple and Quadruple Leg Bridle Slings Double Basket Slings; Horizontal Angle [Note 1] 90° 60° 45° 30° 60° 45° 30° in mm lb lb lb lb lb lb lb; 7/32 5. Safety Factors inc the angle of lift, temperatures, grading of steel chain, legs and more. False (It's 4) Temperatures higher than 250°F (121°C) can cause a permanent reduction in the rated load of a chain and its sling fittings due to the annealing effect from the heat. 5: 2,700: 4,700: 3,800: Jan 18, 2024 ยท The working load limit is calculated by dividing the MBL, or minimum breaking load, by the safety factor applied to that particular product. 4 states, “The design factor for alloy steel chain slings shall be a minimum of 4. Lift dynamics, duty cycle and hitch type may require an increased design factor, hence a reduced WLL. Unsupported Browser - Some functions may be limited in this browser. ASME 830. Chain slings often have a design factor of four to one. Most, but not all slings have a design factor of five to one. • Expose chain slings to chemicals, particularly acidic conditions, without consulting the supplier. • cleaUse chain slings at temperatures above 200°C or below minus 40°C without consulting the supplier. • Force, hammer or wedge chain slings or their fittings into position. The standard safety factor for chain slings is two. Work out the SWL of Chain Slings using the Load Chart. • Lift on the point of a hook.
