What is the maximum load of a crane when the boom is at an angle of 40º and extended 53 ft?

To determine the maximum load that a crane can safely lift while the boom is at a specific angle and extended to a certain length, it’s critical to understand the relationship between the angle of the boom, the length of the boom, and the load capacity.

In this scenario, when the boom is positioned at a 40º angle and extended to 53 feet, the maximum load is influenced by the crane's load chart, which typically varies based on the specific model and manufacturer. Most cranes are designed to lift a certain load at various angles and distances based on their engineering specifications.

The calculation involves considering the formula that accounts for the angle of elevation and the effective radius. Generally, the load capacity decreases as the angle of the boom increases because the lifting force is distributed differently. At 40º, the crane can still support a significant load, and at 53 feet, this operational length contributes to a specific load capacity.

The given answer, 5,030 lb, is likely derived from consulting the crane's load rating chart for a boom angle of 40º and a length of 53 ft, reflecting a safe lifting capacity at this configuration. This load is within the realm of safe operation, ensuring that all parameters of stability and lifting
