【国外标准】 Mobile and Locomotive Cranes

Within the general scope defined in Section 1, American National Standard B30.5 applies to crawler cranes, locomotive cranes, wheel-mounted cranes, and any variations thereof that retain the same fundamental characteristics. The scope includes only cranes of the above types that are basically powered by internal combustion engines or electric motors. Side boom tractors and cranes designed for railway and automobile wreck clearance, digger derricks, cranes manufactured specifically for, or when used for, energized electrical line service, knuckle boom, trolley boom cranes, and cranes having a maximum rated capacity of one ton or less are excluded. Special adaptions to the general types of machines covered by this volume, where applicable, fall under this scope. Some basic machine types within this scope are used alternatively for lifting service and for applications not considered to be lifting service. All of the requirements of this volume are applicable to such machines when used for lifting service. However, at a minimum, Section 5-1.11, Chapter 5-2, and Section 5-3.1 of this volume apply to machines when used in other than lifting service.
