Understanding Truck Mounted Crane Load Charts

Load charts are the most critical document for any crane operator. They define the maximum safe lifting capacity at various boom lengths and working radii. Understanding these charts is essential for safe crane operation and proper machine selection.

Every truck mounted crane comes with a load chart specific to its configuration. The chart typically shows the relationship between boom length, working radius, and maximum load capacity. As the boom extends further or the radius increases, the available capacity decreases.

Key factors to consider when reading load charts include the outrigger configuration (fully extended vs. partially extended), the terrain conditions, wind loading, and whether a jib extension is being used. Always refer to the specific load chart for your crane model and configuration.
