National Commission for the Certification of Crane Operators (NCCCO) Lattice Boom Practice Test

The primary purpose of a jib or extension on a crane is to extend reach higher or up and over. This additional structure allows the crane to effectively maneuver and position loads over obstacles or in tighter spaces that a standard boom might not be able to reach. By utilizing a jib, operators can enhance the crane's versatility, enabling them to lift and place materials in precise locations that are otherwise hard to access.

While increasing load capacity, improving stability, and increasing lifting speed are important considerations in crane operations, a jib specifically facilitates the reach of the crane, enabling it to extend its range of motion and operational capabilities in a more efficient manner. This function is critical, especially in construction and industrial settings where positioning is key to successful lifting and placement operations.
