The chart provides information about lifts when the boom length ranges from 33’ to 105.’ This means it covers the full extension of the boom but does not have information about load capacities with a jib attached. Each signifies a specific piece of information about how the crane must be configured for the figures of the chart to be accurate. Let’s look at a load chart for the Grove RT650E as an example: But they should all include the same basic information. But knowing how to read crane load charts is still essential when working with cranes.Įvery manufacturer’s crane load charts will look a little different. And load indicators in the cabs signify when lifts approach or exceed a crane’s capacity. Most lifts are planned using computer simulations these days.
Understanding how to read a crane load chart allows you to calculate the crane’s load capacity as it relates to the boom angle and length.
