What do the values listed in the manufacturer's load chart represent?

The values listed in the manufacturer's load chart represent the rated capacities of the crane. These capacities indicate the maximum weight that the crane can handle under specific conditions, including the boom angle, reach, and configuration. Understanding rated capacities is crucial for crane operators to ensure safe lifting practices and compliance with operational guidelines.

Each crane has different specifications and limits depending on its design and the materials used in its construction. The load chart provides essential information such as the maximum weight the crane can lift at various boom lengths and angles, taking into account factors like the center of gravity and the stability of the crane. This information is vital for preventing overloading, which can lead to tipping or structural failure, ensuring both operator and site safety.

While other choices touch on related aspects, they do not encompass the primary purpose of the load chart, which is to outline the rated capacities specific to that crane model.
