A two-leg sling has the best load capabilities at how many degrees?

• A. 15°
• B. 60°
• C. 30°
• D. 45°

Answer: (B)

When two legs share a lift, the angle between them changes how much each leg must pull. The load is held by the vertical components of both legs, so as the legs spread wider, each leg has to carry more tension to keep the load up. Rigging charts use a practical spread angle, and about 60 degrees between the legs is the standard point where the sling’s working load remains within its rating while still allowing for safe handling and control. Beyond that angle, the tension in each leg climbs quickly and the effective load capacity drops. So, in typical practice, a two-leg sling achieves its best, most reliable load capability at around 60 degrees.
