Full Description

Within the general scope of the B30 Standard, asdefined in Section I of the B30 Standard Introduction,the B30.3 Volume applies to ?construction tower cranes?and ?permanently mounted tower cranes? that are poweredby electric motors or internal combustion enginesand that adjust their operating radius by means of aluffing boom mechanism, a trolley traversing a horizontaljib, or a combination of the two. The cranes maybe mounted on ?fixed bases? or ?traveling bases? andmay have tower and supporting structure arrangementsthat permit the crane to climb in a structure being builtor that permits increasing the crane?s tower height asthe structure rises. Variations of the above physical characteristicsthat provide the same fundamental operatingcharacteristics are included in the scope of this Volume;however, the requirements of thisVolume are only applicableto the cranes within this scope when they areused in lifting operations. Mobile cranes configured withtower attachments (refer to ASME B30.5) andself-erecting tower cranes (refer to ASME B30.29) arenot within the scope of this Volume.
