Lift Capacity Calculator

The lift chart value at three metres is irrelevant if you cut at seven. Enter the figure from the chart at your real working radius and configuration, pick or type the attachment package, and see what is left for the tree.

From the manufacturer's chart: correct boom and stick, counterweight, over-front or over-side, radius and height.
Allowance for dynamic loads when slewing, uneven ground and estimation error. Set your own policy.
Illustrative. Green dense hardwood is often around or above 1,000 kg/m³; softwoods are lower. Use your own species data.
