AS 1418.18 – 2001 Cranes, Hoists and Winches
Part 18: Crane Runways and Monorails
AS 1418.18 – 2001 Cranes, Hoists and Winches Part 18: Crane Runways and Monorails specifies the general requirements for runway girders and monorails constructed of structural steel. Deflection limits and construction tolerances for structures supporting the runway girders are also covered by this Standard.
This Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee ME-005, Cranes. This Standard incorporates Amendment No. 1 (March 2003) and Amendment No. 2 (November 2003). The changes required by the Amendment are indicated in the text by a marginal bar and amendment number against the clause, note, table, figure or part thereof affected.
Runway girders are the subject of much debate relating to their method of design, as some people regard them as a part of the building structure that houses and supports the crane and others regard them as an integral part of the crane. This Standard allows for the design of runway girders by either limit states or permissible stress methods to allow their design by those engineers who favour either method. However, in choosing to design the runway girders by one method, the designer must use that exclusively throughout the design.
This Standard has been introduced in recognition that there is currently little guidance given to aid designers in designing runway girders. It is intended that the Standard will give direction on the correct implementation of the appropriate structural design Standards with a view to producing a uniform design method for crane runways and monorails.
