Mobile crane load chart capacities are based on what factors?

The load chart capacities for mobile cranes are fundamentally based on structural limits and stability. These factors determine how much weight a crane can safely lift without risking its integrity or tipping over. The structural limits refer to the maximum forces that the crane's components (like the boom, chassis, and outriggers) can withstand during operation. Similarly, stability is a crucial aspect, as it involves the crane's balance and how it distributes loads during lifting operations.

Taking into account various elements such as the center of gravity of the load, the crane’s configuration, and ground conditions also plays a significant role in ensuring safe lifting practices. The load chart provides specific capacities based on these considerations, ensuring that operators can make informed decisions regarding the safe handling of loads.

Other factors, while important for operational safety, are secondary to the fundamental structural integrity and stability that directly influence the crane's lifting capabilities.
