For complex lifts, engineers calculate (actual load / crane’s rated capacity at given radius). Staying under 75-85% (depending on standard) is best practice.

The Crosby Group, a premier manufacturer of lifting and rigging hardware.

Spreader beams convert low sling angles into pure compressive forces across the beam, protecting the load from crushing. To calculate the compressive force ( Fccap F sub c ) acting on a spreader bar:

Calculating if the soil or concrete can withstand the immense pressure exerted by the crane's outriggers. Moving Beyond the PDF Free Download For complex lifts, engineers calculate (actual load /

Never guess the weight of a load. Engineers use shipping documents, manufacturer blueprints, or material density formulas (Volume × Material Density) to determine the exact weight before choosing rigging components. 2. Essential Rigging Formulas Every Engineer Needs Spreader beams convert low sling angles into pure

The Center of Gravity is the exact point where an object balances perfectly in all directions. If the hoist hook is not positioned directly above the CG, the load will tilt, swing, or slide when lifted. This sudden movement introduces dynamic forces that can snap rigging gear.
