Remember to always measure the maximum capacity by the shortest lift, which is usually over the rear of the crane with the outriggers fully extended. To graph out the lift, the feet on the left axis represent the radius (or distance) from the center pin to the center of the load. The legend on the chart shows the specific lift the crane needs to do.

The other columns indicate the weight load for each axle. When looking at the load chart, the first number along the top axis is the gross vehicle weight. Also, the transport weight affects which trailer to use, how to load the crane onto the trailer, the transportation route, and the type of permit to get for the job. This information is important if you’re working in a tight space since the lifting capacity depends on the use of the outriggers. The load chart shows the crane dimensions, as well as the data for the outriggers, transport weight, and steering dimensions. Let’s take a look at how these variables can affect your specific project. To calculate the crane capacity index, use this formula: (Average (radius x max (lifting height x capacity))) / 100. You may need to find the Crane Capacity index for the load chart. Determining the crane load capacity ensures a safe work environment and allows the project to proceed smoothly. One of the biggest calculations affecting any construction project is the crane load capacity.
