Within the general scope defined in Section I of the B30 Standard Introduction, American National Standard B30.5 applies to crawler cranes, locomotive cranes, wheelmounted 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 1 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 apply to machines when used in other than lifting service. 在B30标准介绍第一节定义的一般范围内,美国国家标准B30.5适用于履带式起重机,机车起重机,轮式起重机及其保留相同基本特性的任何变体。范围仅包括上述类型的起重机,这些起重机基本上由内燃机或电动机提供动力。不包括设计用于铁路和汽车残骸清理的侧臂牵引车和起重机、挖掘机井架、专门为通电线路服务制造或用于通电线路服务的起重机、折节臂、小车吊臂起重机以及最大额定容量为 1 吨或更小的起重机。 在适用的情况下,对本卷所涵盖的一般类型的机器的特殊调整属于此范围。 此范围内的一些基本机器类型可替代用于起重服务和不被视为起重服务的应用。本卷的所有要求均适用于用于起重服务的此类机器。但是,至少,第 5-1.11 节、第 5-2 章和第 5-3.1 节适用于用于起重服务以外的机器。
