How far can the boom of the Arva Crane extend?

The boom of the Arva Crane is designed to extend up to 15 feet, making this the correct answer. The extension capability of a crane's boom is crucial, as it allows operators to reach specific heights and distances necessary for lifting and placing loads safely and efficiently. Understanding the boom's extension is essential for proper operation, ensuring that the crane can effectively handle tasks within its specified range while maintaining stability and safety.

Options that indicate a shorter length, such as 10 feet, 12 feet, and 20 feet, are either not indicative of the Arva Crane's specifications or exceed its design limits. Knowing the precise capabilities of the boom is vital for plan and execution in lifting operations, ensuring that the crane works within its safe operational parameters.
