What is the maximum lift capacity of a crane based on?

The maximum lift capacity of a crane primarily depends on the crane type, configuration, and load chart. Each crane has specific engineering characteristics, including its physical structure, boom length, and setup arrangements that determine how much weight it can safely lift under various conditions. The load chart provides specific information about the maximum capacity for different configurations of the crane, such as angle of the boom and distance from the center of rotation. This information is crucial for ensuring safe operations, as it takes into account the crane's design limits and operating conditions.

Understanding and adhering to the load chart is vital for crane operators and signal persons because lifting beyond these indicated weights can compromise the stability of the crane, leading to accidents and equipment failure. Hence, knowing the crane's type, configuration, and how to interpret the load chart ensures that lifting operations are conducted safely and efficiently.
