What is the primary function of a boom angle indicator on cranes or derricks?

• A. To measure load weight
• B. To indicate boom length
• C. To display the angle of the boom
• D. To regulate hydraulic pressure

Answer: (C)

The primary function of a boom angle indicator on cranes or derricks is to display the angle of the boom. This device provides critical information needed to assess the position of the boom relative to the ground. By indicating the boom angle, operators can determine how high or low the boom is lifted and how far it reaches out horizontally. This information is essential for ensuring safe operation, as it helps in preventing potential overloading of the crane and ensures that lifting operations are performed within safe limits. It contributes to the overall safety and efficiency of crane operations by allowing operators to make informed decisions based on the current boom position during lifting tasks.
