10、s (ISOmember bodies). The work of preparing International Standards is normally carried out through ISO technicalcommittees. Each member body interested in a subject for which a technical committee has been established hasthe right to be represented on that committee. International organizations, go
11、vernmental and non-governmental, inliaison with ISO, also take part in the work. ISO collaborates closely with the International ElectrotechnicalCommission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC D
12、irectives, Part 3.Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the el

21、 this part of ISO 13562 ensure that the type of truck specified has satisfactory stabilitywhen reasonably and appropriately used under the following normal operating conditions:a) stacking with the fork arms reasonably horizontal, with the truck on substantially firm, smooth, level andprepared surfa

23、 position, with the truck on substantially firm,smooth and prepared surfaces;c) operating with the load centre of gravity approximately on the longitudinal centre plane of the truck.3.2 Operating under conditions other than normalWhen the operating conditions differ from those specified in 3.1, it i
24、s necessary to use eithera) a truck complying with other International Standards covering different specific conditions (e.g. ISO 10658), orb) a truck whose stability is agreed upon between the interested parties. This agreed stability shall not be lessthan that required by the tests specified for n
25、ormal operating conditions in 3.1.4 Stability tests4.1 Test requirementsThe stability of industrial variable-reach fork-lift trucks shall be verified by one of the procedures specified in 4.2.4.2 Verification procedures4.2.1 Tilting platformUse a test platform that can be tilted about one side. Plac
26、e the truck being tested for stability on the initiallyhorizontal test platform, in accordance with 4.3 and, successively, in each of the positions described in Table 3.In each of the tests, tilt the test platform slowly to the slope specified in Table 3.The truck is considered stable if it passes a
27、ll tests without overturning. For the purposes of the tests, overturning isdefined as the test platform slope value that, if increased, would cause the truck to overturn.It is permissible in lateral tests for one load wheel to lose contact with the test platform. It is acceptable for parts ofthe str
28、ucture or designed features to make contact with the test platform.4.2.2 Fixed slopeUse fixed slopes with inclinations equivalent to the specified test slope. The slope surface shall be smooth andcapable of supporting the truck mass with no deformation that could affect the test results.Drive the tr
29、uck under test onto the fixed slopes with the boom in the lowered and retracted position and positionedas specified in Table 3. For each of the truck positions with an elevated load or load carrier, the boom shall beelevated and extended smoothly to the position specified in Table 3.4.2.3 Calculatio
30、nDetermine compliance with the specified stability values by calculation methods verified by empirical data.The calculated capacities shall take into account manufacturing variations and deflections of the boom, tyres, etc.4.3 Test conditions4.3.1 Condition of the truckThe tests shall be carried out

32、ving a mass of 90 kg if the stability during a test is therebydecreased. The centre of gravity of the object shall be secured 150 mm above the seat index point (SIP) asdetermined in accordance with ISO 5353, with the seat at the closest position to the midpoint of the adjustmentsprovided.Fuel tanks
33、of internal combustion engine trucks shall be full if the stability is thereby decreased. All other tanks shallbe filled to their correct operating levels, as applicable.Tyres shall be inflated to the pressure specified by the truck manufacturer. Where tyre ballast is incorporated in thetruck design
34、, the use of ballast shall be in accordance with the truck manufacturers instructions.4.3.2 Position of truck on platformFor tests 1 and 2 (see Table 3), the truck shall be placed on the test platform or slope so that the load axle isparallel to the tilt axis, XY, of the test platform.For tests 3, 4
35、 and 5 (see Table 3), the truck shall be placed on the test platform or slope in a turning position withthe line MN parallel to the tilt axis, XY, of the test platform.For trucks with an oscillating steer axle, the wheel on the steer axle nearest to the platform tilt axis shall be parallelto the pla
36、tform tilt axis.Lateral stability tests shall be conducted on the side of the truck which is the less stable.Point N is the centre point of the area of contact between the test platform surface and the front wheel or stabilizerpad nearest to the tilting axis of the test platform.Point M is defined a
37、s follows.a) For trucks with an oscillating steer axle: the projection onto the test platform of the intersection of thelongitudinal centre plane, AB, of the truck with the axis of the steer axle.b) For trucks with an articulated chassis: the projection onto the test platform of the intersection of
38、the longitudinalcentre plane, EF, of the rear chassis module and the axis of the rear axle.c) For trucks with axle locking: the centre point of the area of contact between the test platform and the rearwheel nearest the test platform tilting axis.4.3.3 Test loadThe test load shall have a mass equiva
39、lent to the maximum load, Q, which the truck can elevate to its maximum liftheight acting through the centre of gravity, G, nominally positioned at the standard load centre distance, D,asindicated on the capacity plate of the truck both horizontally from the front face of the fork arm shank and vert
40、icallyfrom the upper face of the fork arm blade (see Figure 1).When additional lift heights, loads and load centre distances are to be indicated on the capacity plate, the truckshall meet the requirements established by the tests specified in this part of ISO 13562 for these additional ratings.The c
41、entre of gravity, G, of the test load shall be located on the longitudinal centre plane, AB, of the truck.Copyright International Organization for Standardization Provided by IHS under license with ISONot for ResaleNo reproduction or networking permitted without license from IHS-,-,-ISO 13562-1:2000
