11、(ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, g
12、overnmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to
13、 the member bodies for voting. Publication as an International Standard requires approval by at least75% of the member bodies casting a vote. International Standard ISO509 was prepared by Technical Committee ISO/TC110, Industrial trucks, Subcommittee SC2, Safety of powered industrial trucks. It canc
14、els and replaces, the Recommendation ISO/R509:1966, of which it constitutes a technical revision.iv blankBSISO 509:1996 BSI 11-1999 1 1 Scope This International Standard specifies the principal dimensions for pallet trucks for transporting flat pallets complying generally with ISO6780 and their load
15、s. The dimensions apply to the heights, widths and lengths of the fork arms of pallet trucks which may have either single or tandem trail wheels. It should not be inferred that the use of a particular size of pallet truck is restricted to one particular size of pallet. NOTE 1The pallet dimensions sh
16、own inFigure 2 are informative only and are given in anticipation of an amendment toISO6780 of the entry dimensions of full perimeter base pallets as defined in ISO445. The amendment is intended to bring ISO6780 into line with existing practice. 2 Normative reference The following standard contains
17、provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the
18、 possibility of applying the most recent edition of the standard indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO 6780:1988, General-purpose flat pallets for through transit of goods Principal dimensions and tolerances. 3 Truck dimensions 3.1
19、 Fork arm heights 3.1.1 In the unloaded condition and in the lowered position the fork arm height dimensions of pallet trucks shall be as follows: a) the distance between the underside of the fork arms and the ground, F (seeFigure 1 and Figure 2), shall be a minimum of30mm; b) the height of the fork
20、 arms from the ground at the point of entry, G 1(seeFigure 1), shall be a maximum of86mm; c) the height of the fork arms from the ground at the heel of the truck, G 2(seeFigure 1), shall be a maximum of90mm. 3.1.2 In the unloaded condition and the raised position, the fork arm height dimension of pa
21、llet trucks shall be such that the height of the top surface of the fork arms from the ground, H (seeFigure 1), shall be a minimum of185mm. 3.2 Fork arm widths 3.2.1 Distance between fork arms For pallet trucks, the distance between fork arms, E (seeFigure 1), shall be a minimum of180mm. NOTEFigure
22、1 illustrates a pallet truck with tandem trail wheels, as this type of truck has the greatest overall dimensions over the wheels. Figure 1 Truck dimensionsBSISO 509:1996 2 BSI 11-1999 3.2.2 Overall width over fork arms The overall width over fork arms, D (seeFigure 1), in relation to the correspondi
23、ng dimensions of pallets in accordance with ISO6780 shall be as follows. a) D shall not exceed570mm for trucks corresponding to pallets having a minimum entry width of590mm (pallets800mm wide). b) D shall not exceed690mm for trucks used in conjunction with pallets having a minimum entry width of720m
24、m (pallets1000mm or more wide). 3.3 Fork arm lengths NOTE 2Dimensions A, B and C are related to the dimensions of the pallet and the minimum openings in the bottom deck, which are symmetrically disposed about the axes of the pallet. See ISO6780. The overall length of fork arms, A (seeFigure 1), shal
25、l not exceed the value inTable 1 corresponding to the appropriate nominal value of l or w as defined in ISO6780. 3.4 Wheel position Dimension B is the shortest possible distance between the heel of the truck and the nearest point of the trail wheel closest to the heel. Dimension C is the largest pos
26、sible distance between the heel of the truck and the furthest point of the trail wheel furthest from the heel (seeFigure 1). Dimensions B and C control the positioning of the trail wheels relative to the heel of the truck during lifting. The values of dimensions B and C shall be such that, when the
27、wheels pass through the minimum size of openings in the bottom deck of the pallet, a minimum clearance J of6mm is maintained between the components of the truck and the edges of the deck members forming the opening in the bottom deck of the pallet (seeFigure 3). When the truck is operated so that th
28、e distance between the underside of the fork arms and the ground is34mm or greater, the clearance J should also be maintained at the upper side of the bottom deck.
