摘要

Whatever resistance exist-ed in the past to opera-tional devices such as load moment indica-tors, rated capacity indicators and rated capacity limiters, last years revised ANSI/ASME B30.5 standard effectively put an end to the resistance. The key change was the requirement that all cranes with a maximum rated load capacity of three tons or more have an LMI, an RCI or an RCL. The standard is mandatory for new cranes, but not necessarily for existing cranes. Older cranes must have their performance reviewed if they have been modified in a way that changes that performance substantially, and the reviewer could suggest retrofitting the crane with an operational aid.
