Review of Australian Standards.To keep abreast of progress in industry, Australian Standards are subject to periodic review and are kept up to date by the issue of amendments or new editions as necessary. It is important therefore that Standards users ensure that they are in possessi
6、on of the latest edition, and any amendments thereto. Full details of all Australian Standards and related publications will be found in the Standards Australia Catalogueof Publications;this information is supplementedeach month by the magazineThe Australian Standard, which subscribing members recei

Suggestionsfor improvementsto Australian Standards, addressedto the head office of Standards Australia, are welcomed. Notification of any inaccuracy or ambiguity found in an Australian Standard
8、should be made without delay in order that the matter may be investigated and appropriate action taken. This Standard was issued in draft form for comment as DR 94409.

10、Australia/Standards New Zealand Committee ME/5 on Cranes as AS 1418.171995, Cranes (including hoists and winches), Part 17: Design and construction of workboxes. It has been introduced to fill a need in the workplace. This Standard is a result of a consensus among representatives on the Joint Commit
11、tee to produce it as an Australian Standard. This Standard has been introduced in recognition that the practices involved in using workboxes are often inherently dangerous and this Standard sets out to expressly avoid failure of the workbox structure. Whilst the factors of safety introduced in the d
12、esign of workboxes are of a nominalmagnitude,thedesignerhas beenprovidedwith the opportunity to increase the factors of safety in conformance with the intended future use of the workbox. The introductionof this Standard may not be takenas recommendingthe use of workboxes and it is purposely restrict
13、ive to limit their application. The term informative has been used in this Standard to define the application of the appendix to which it applies. An informative appendix is only for information and guidance. CopyrightSTANDARDS AUSTRALIA Users of Standards are reminded that copyright subsists in all

COPYRIGHT Accessed by UNIVERSITY OF SOUTH AUSTRALIA on 24 May 2007 AS 1418.17 19966 S E C T I O N2D E S I G N 2.1GENERALThe design of workboxes shall be in conformance with AS 1418.1. The design load shall be not less than 2.5 static loading. NOTE: The
40、2.5 design load factor takes account of the hoisting factor and that personnel are being lifted. 2.2MATERIALS FOR CONSTRUCTIONThis Standard is generally written for workboxes fabricated from a minimum of grade 250 carbon steel plate and sections. However, other materials such as aluminium, glass fib
41、re reinforced plastics, stainless steel and timber, may be used in construction providing that it is demonstrated by calculation and tests that such materials provide an equal degree of structural integrity. 2.3LIFTING ATTACHMENTSWorkboxesshallbeprovidedwithanadequate number of lifting attachments t
42、o provide an adequate distribution of the design load in relation to the size of the workbox. In the case of multiple suspension fittings, the design shall be based on the assumption that the load is carried by two lifting attachments only. 2.4SUSPENSION SLINGSWorkbox suspension sling sets shall be
43、made out of flexible wire ropes or chains. They shall be securely attached and dedicated to the workbox by moused shackles, hammer lock shackles or other means. In the case of multiple leg slings, the static loading on each shall be estimated on the basis that only two carry the load. In no case sha
44、ll the factor of safety of each suspension sling be less than 8 for chains or 10 for wire rope, based on the guaranteed breaking force of the slings. 2.5STABILITYWorkbox suspension systems shall be designed to minimize angular tipping of the workbox due to the internal movement or positioning of per
45、sonnel or loading. When the workbox is loaded asymmetrically, the maximum allowable longitudinal and transverse tipping angle shall be 5 at the following conditions (a)load:safe working load has been added to the workbox; (b)area of loading:30% of floor area; (c)longitudinal load location:one extrem
46、e end of the workbox; and (d)transverse load location:one extreme side of the workbox. 2.6FLOOR DESIGN 2.6.1Load distributionThe workbox floor shall be designed to accept the design load concentrated in 30% of the floor area in all locations. 2.6.2Floor sizeWorkbox floor area shall be not less than
47、0.2 m 2 per person. The internal dimension shall be not less than 500 mm on any side or diameter. 2.6.3Floor surfaceThe workbox floor shall be flat, slip-resistant and in conformance with AS 1657. Provision for self-draining from the workbox shall be provided. 2.7WORKBOX SIDES 2.7.1GeneralThe workbo
