Specifies requirements, additional to those in AS 1418.1, for tower cranes of the ram luffing, rope luffing, saddle jib (hammerhead), articulated saddle jib, and self-erecting types. Application, loading, design, controls and indicating devices, equipment, access, marking, and inspection and testing are covered. Appendices provide guidance on information to be supplied with an inquiry or order, and by the manufacturer, illustrations of typical types of cranes, typical classifications of the crane as a whole and crane mechanisms.

This Standard sets out requirements for (a) power-driven tower cranes that are dismantled when they have served their purpose; and(b) tower cranes of the permanently erected type,as defined in AS 2549.Horizontal jib and luffing jib and boom cranes are included, and the cranes may be of the travelling, fixed, or climbing type.Power-driven mobile cranes fitted with tower crane configurations are excluded except for the stability and foundation considerations when used in the capacity of a tower crane.The Standard covers requirements from and including the hook to the anchorages of the tower crane as well as requirements for rail-mounted types.NOTES: 1 Guidance on information to be supplied with an enquiry or order is given in Appendix A.2 Guidance on information to be supplied by the manufacturer is given in Appendix B.3 Guidance on selection and operation of tower cranes is given in AS 2550.4.
