Crane Lifting Plan Calculator

Enter your crane's make, model, rated capacity and boom length, work out total load, radius and load chart utilisation against your own limit, then download a lifting plan PDF.

This tool does not contain manufacturer load charts. Enter the capacity from the load chart for your exact crane configuration. It supports, but does not replace, a lift plan approved by a competent appointed person and your emirate authority's requirements. See also the crane handover tracker.
