What should an operator be aware of when a load is leaving the ground?

When a load is leaving the ground, the operator needs to be aware that it may cause the radius to increase. This is important because as the load is lifted, the angle between the load and the ground changes, which can result in an increase in the radius from the center of the crane to the load's attachment point. This is a critical factor in crane operations as it affects the crane's stability and capacity to safely lift the load.

An increase in radius can lead to a decrease in the crane's lifting capacity due to the leverage and torque involved, which makes monitoring and managing the load's position essential for safe operations. Operators must always keep an eye on various factors affecting crane stability and load management during lifting operations, including changes in radius as loads are moved. Understanding this concept allows operators to make informed decisions about lifting maneuvers and ensure the safety of the lifting process.
