| Abstract |
This standard (approved as an American National Standard: 16 Nov. 1981) is a revision of ANSI B30.4-1973 and applies to the construction, installation, operation, inspection and maintenance of portal, tower and pillar cranes and others having the same fundamental characteristics. Sections are devoted to: scope, definitions and references; construction characteristics (assembly, load ratings and stability, runway track, trucks, rail sweeps and safety lugs, guards for moving parts, limit switches, cabs and remote control stations, footwalks, boom hoist and load hoist mechanisms, swing mechanism, controls, hoisting equipment); inspection, testing and maintenance; operation (operator qualifications and operating practice, handling the load, signals). Appendices illustrate the danger zones for cranes and lifted loads operating near electrical transmission lines, and standard hand signals for banksmen. |
