Calculate crane lifting capacity.
Crane Safe Load Calculator
Calculate estimated Safe Working Load (SWL) based on radius and crane specs.
Angle of Boom
70°
Safe Working Load (SWL)
15.4 Tons
* Capacity reduces significantly as radius increases.
Safety Disclaimer: This tool uses a simplified geometric formula for estimation. In real-world cranes, SWL is determined by the manufacturer's load charts, which account for stability, structural integrity, and wind conditions. NEVER exceed the crane manufacturer's official load chart.
