Description

B30.4 applies to the construction, installation, operation, inspection, testing and maintenance of electric motor or internal-combustion engine powred portal and pedestal cranes, that adjust operating radius by means of a boom luffing mechanism or by means of a trolley traversing a horizontal boom, that may be mounted on a fixed or traveling base, and to any variation thereof that retain the same fundamental characteristics. This standard applies only to portal and pedestal cranes utilizing a drum and wire rope for hoisting and which are used for hoisting work. The requirements for tower cranes (refer to ASME B30.3), telescopic boom cranes (refer to ASME B30.5), and knuckleboom cranes (refer to ASME B30.22) are not included in this standard.
