About this calculator

Use case

Scale a rated capacity to a working radius.

Apply a radius ratio and duty factor to the rating you enter. The manufacturer load chart governs.

Range notes

Supports imperial short ton/ft and metric tonne/m inputs.

Planned load is compared against the scaled value for a utilization figure.

The scaled value is not a chart capacity; use the manufacturer load chart.
