What does the term "boom angle" refer to in crane operation?

The term "boom angle" refers specifically to the angle of the crane boom in relation to the horizontal level. This angle is critical in crane operations as it affects the crane's lifting capacity and stability. The boom angle determines how much load the crane can safely lift and move, as well as how far the load can be extended from the crane's center of rotation. A greater boom angle can result in reduced lifting capability due to increased leverage on the crane's structure.

Understanding the boom angle is essential for safe crane operation, as it ensures that operators can work within the equipment’s operational limits and avoid potential accidents. By maintaining the correct boom angle, crane operators can ensure they are working efficiently and safely.
