How It Works +
This calculator determines the safe working load for a crane based on several key parameters:
- Crane Rated Capacity: The maximum load the crane can lift under ideal conditions
- Boom Length: The length of the crane’s boom in feet
- Working Radius: The horizontal distance from the crane’s center to the load
- Boom Angle: The angle of the boom relative to horizontal
- Safety Factor: A multiplier applied to ensure safe operation (typically 1.5-2.0)
The calculation uses the formula: Safe Working Load = (Rated Capacity × sin(Boom Angle)) / (Safety Factor × (1 + Radius/Boom Length))
This simplified formula provides a conservative estimate. Always consult manufacturer load charts for precise calculations.
