Description
B66C covers crane systems and their load-handling components, encompassing fixed, mobile, and floating cranes along with associated mechanical devices for lifting and transporting heavy loads. It includes load-engaging elements such as hooks, grabs, magnets, and spreader bars, as well as auxiliary equipment like capstans and winches used in conjunction with cranes. The subclass also addresses structural features, control mechanisms, and safety systems integral to crane operation, but excludes specialized lifting devices covered by other classes such as jacks (B66F) or elevators (B66B).
