What does the term "upperworks" or "superstructure" refer to in a crane?

The term "upperworks" or "superstructure" in the context of a crane refers specifically to the components located above the turntable. This includes the boom, hoist, and counterweights, which are vital for the crane's operation as they allow for lifting and maneuvering loads. The superstructure is where the critical machinery and operator controls are situated, enabling the crane to perform its functions effectively.

Understanding this terminology is essential for anyone operating or working around cranes, as it delineates the structural parts that bear the burden of lifting operations, and helps clarify communication in safety and operational procedures.
