A typical digger derrick lifting-capacity chart at 45° indicates the boom will reach how far from the center of the boom pedestal?

Understanding the lifting-capacity chart for a digger derrick is essential for safe and effective operation. These charts provide valuable information about how much weight the machine can lift at various angles and distances from the pedestal.

In this instance, the lifting-capacity chart indicates that when the boom is positioned at a 45° angle, it can extend 24 feet from the center of the boom pedestal. This distance allows the operator to safely lift and position materials at a considerable reach without exceeding the machine's operational limits.

The choice of 24 feet reflects both the design specifications of the digger derrick and the physics involved—specifically, how load distribution and angles affect the machine's stability and lifting capability. Observing these operational parameters is crucial for ensuring safety and compliance with manufacturer guidelines.

While other distances might seem plausible, they do not align with the standard specifications provided for this type of equipment at a 45° boom angle, making 24 feet the most accurate answer.
