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 lift at a specific boom angle and extension, one typically refers to the crane's load chart. The load chart provides the safe lifting capacities considering various parameters like boom angle, boom length, and the configuration of the crane.

When the boom is extended to a length of 53 feet at an angle of 40º, the loading capacity is determined by the mechanical advantage offered by this configuration. The crane's design and specifications dictate how much weight can be safely lifted at that particular angle and distance, taking into account factors such as stability, counterweights, and the dynamics of the lift.

In this scenario, the calculated load for a boom length of 53 ft at a 40º angle results in a maximum load of 5,030 lb. This figure aligns with the safety and operational limits outlined in the crane's load chart, ensuring that the lift remains within safe parameters to prevent tipping or structural failure.

Understanding the load chart is crucial for crane operation, as it helps in making informed decisions regarding lifting capacities under varying conditions.
