What does the boom angle indicator show?

The boom angle indicator specifically displays the angle of the boom relative to the horizontal plane. This information is vital for operators as it helps them understand the boom's positioning and ultimately assists in maintaining safe operating conditions. By knowing the boom's angle to the horizontal, crane operators can ensure that they are not exceeding the manufacturer's specified limits for lifting and can make informed decisions about load positioning and stability. This is crucial for preventing issues like tipping or overload, emphasizing the importance of being aware of how the boom's angle affects the overall balance and control of the crane during operations.
