What factors may limit the capacities on a load/capacity chart?

The structural strength of the crane and its stability are critical factors that directly influence the capacities indicated on a load/capacity chart. A crane’s design, materials used in construction, and overall structural integrity determine how much weight it can safely lift without risking failure. Stability is also paramount; if a crane is not stable, it can tip over even with loads that fall within its rated capacity due to poor balance or unsuitable ground conditions.

Load/capacity charts provide essential guidance for safe lifting, reflecting the maximum safe working loads for various conditions. For instance, various configurations, such as boom length, jib utilization, and load radii, impact the safe load capacity as determined by both structural strength and temporal stability. Thus, understanding the engineering aspects of the crane is crucial for ensuring safe and effective operation.
