Which crane accessory allows additional vertical reach to increase lift height?

• A. Counterweight
• B. Base
• C. Hoist
• D. Jib

Answer: (D)

The key idea here is extending the crane’s reach. A jib is the crane accessory designed for that purpose. It’s an additional arm attached to the crane that can be extended and angled. When you angle a luffing jib upward, you gain extra vertical reach, allowing the load to be lifted higher than with the main boom alone. This capability is what makes the jib the right choice for increasing lift height. In contrast, a counterweight is used to balance the crane and keep it stable; the base is just the foundation anchoring the crane to the ground; and the hoist is the lifting mechanism itself, which raises and lowers the load but doesn’t extend the crane’s reach.
