What type of capacity can typically be found on a crane load chart?

The capacity indicated on a crane load chart is typically referred to as "static" capacity. This represents the maximum load that the crane can lift under stable and controlled conditions, without any dynamic forces at play, such as wind or accelerations from sudden movements. The static capacity is calculated based on factors such as the crane's configuration, boom length, and the working radius from the center of rotation to the load. Understanding this capacity is crucial for safe crane operation, as it ensures that the crane is within its limits when lifting and moving loads.

In contrast, dynamic capacity refers to loads that might be affected by movement or external forces, which are not the basis of the static figures outlined in the load chart. Variable capacity does not specifically exist as a distinct type of capacity on most load charts; it generally refers to the varying nature of weights or load configurations. Rated capacity is another term used to describe maximum lifting capability but is not synonymous with static as it may include considerations beyond standard conditions.
