AS 5246.1:2021 pdf download.Cranes -Classification Part 1: General (Iso 4301-1:2016, MOD).

The classification is applied by the purchaser and the manufacturer of a crane and/or load lifting attachments, between which

agreement is necessary on the duty of the crane. The classification thus agreed Is Intended for contractual and technical reference purposes.

It is also used to specify the service conditions of cranes, load lifting attachments, or components which are designed for serial manufacture and allows such items to be selected in accordance with their intended use.

The specified classification shall be documented in the crane manuals.

5.3 Use of classification in the design

The second purpose of classification is to provide a basis for the designer to build up his analysis of the design and to verify

that the crane or component is capable of achieving the intended life under the specified service conditions of the particular

application.

As a person skilled in crane technology, the designer takes the specified service conditions, either provided by the purchaser or

predetermined by the manufacturer (as is the case in the design of serial equipment), and incorporates them into the assumptions on which his analysis is based, having regard to all other factors which influence the proportioning of components.

Crane operation gives rise to stress or load histories in crane structures and components (e.g. wire ropes. slewing bearings, or

wheels and rails). These histories may be classified for the particular component. The method of determining this classification is set out in the appropriate standards, e.g. for structures in Iso 20332.
