A jib crane is defined as what?

• A. A crane with multiple trolleys.
• B. A crane with a horizontal boom and a single leg.
• C. A crane that moves on a vertical axis only.
• D. A crane that cannot extend its reach.

Answer: (B)

A jib crane is indeed characterized by having a horizontal boom, known as a jib, which is anchored to a vertical post or leg. This design allows the jib to extend outward, providing the crane with the capability to lift and move loads at various angles, depending on the position of the boom. The single leg supports the jib and allows it to pivot, enhancing its versatility in lifting and maneuvering heavy loads in a designated area. The defining feature of the jib crane is its horizontal boom that can operate within a specific radius, which is often adjustable, making it particularly useful in environments where space is limited. This functionality distinguishes it from other types of cranes that may not have the same operational characteristics or mobility.
