The work of
9、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, governmental and non-governmental,
10、 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. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft Inte
11、rnational 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 elements of this part of ISO
12、 13563 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 13563-1 was prepared by Technical Committee ISO/TC 110, Industrial trucks, Subcommittee SC 2, Safety of powered industrial trucks. This part of ISO
13、13563 has been prepared using EEC 89/240 Method 5 as a basis. ISO 13563 consists of the following parts, under the general title Single side loading fork-lift trucks: Part 1: Stability tests Part 2: Additional stability tests for trucks handling freight containers of 6 m length and above Copyright I

20、SO 13563 ensure that the type of truck specified has satisfactory stability when reasonably and appropriately used under normal operating conditions, as follows: a)operating (travelling and stacking) on substantially firm, smooth, level and prepared surfaces; b)travelling with the mast or fork arms
21、tilted backwards and the load retracted and in the lowered (travelling) position, or resting on the load-carrying deck; c)stacking with the mast substantially vertical and the fork arms substantially horizontal; d)operating with the load centre of gravity approximately on the centre plane between th
22、e mast uprights. 3.2Operating in conditions other than normal When the operating conditions differ from those specified in 3.1, it is necessary to use either a)a truck complying with other parts of ISO 13563 covering different specific conditions, or b)a truck whose stability is agreed upon between
23、the interested parties; this agreed stability shall not be less than that required by the tests specified for normal operating conditions in 3.1.

25、2. 4.2Verification procedure 4.2.1Tilting platform Use a test platform that can be tilted about one side. Place the truck being tested for stability on the initially horizontal test platform, in accordance with 4.3 then, successively, in each of the positions described in Table 3. In each of the tes
26、ts, slowly tilt the test platform to the slope specified in Table 3. The truck is considered stable if it passes all tests without overturning. For the purposes of the tests, overturning is defined as the test platform slope value that, if increased, would cause the truck to overturn. It is permissi
27、ble in lateral tests for one load wheel to lose contact with the test platform. It is acceptable for parts of the structure to make contact with the test platform. 4.2.2Fixed slope Use fixed slopes with inclinations equivalent to the specified test slope. The slope surface shall be smooth and capabl
28、e of supporting the truck mass with no deformation that could affect the test results. Drive the truck under test onto the fixed slopes with the mast lowered and positioned as specified in Table 3. For each of the truck positions with an elevated load or load carrier, the mast shall be elevated smoo
29、thly to the position specified in Table 3. 4.2.3Calculation Compliance with the specified stability values may be determined by calculation methods verified by empirical data. The calculated capacities shall take into account any manufacturing variations and deflections of the mast, tyres, etc. 4.3T
30、est conditions 4.3.1Condition of the truck The tests shall be carried out on an operational truck. The operator on rider-controlled trucks shall be simulated by an object having a mass of 90 kg if the stability during a test is thereby decreased. For a truck designed for operation with a standing op
31、erator, an object having a mass of 90 kg shall be secured with its centre of gravity 1 000 mm above the floor of the operators platform at the centre of the position normally occupied by the operator. For a truck designed for operation by a seated operator, the centre of gravity of the object shall
32、be secured 150 mm above the seat index point (SIP) as determined in accordance with ISO 5353, with the seat at the closest position to the midpoint of the adjustments provided. Where the operators position can be moved relative to the truck, it shall be located for each test in the position that min
33、imizes the stability of the truck. Fuel tanks of internal combustion engine trucks shall be full if the stability is thereby decreased. All other tanks shall be filled to their correct operating levels, as applicable. Copyright International Organization for Standardization Provided by IHS under lic

Wh
35、ere tyre ballast is incorporated in the truck design, the use of ballast shall be in accordance with the truck manufacturers instructions. 4.3.2Position of truck on platform The truck shall be placed on the test platform or slope with the line MN parallel to the tilt axis, XY, of the test platform.
36、Tests shall be conducted on the side of the truck which is the least stable. Point N is the centre point of the area of contact between the test platform surface and a non-articulating wheel or stabilizer pad. Point M is defined as follows. a)For trucks with an articulating axle: the projection onto
37、 the test platform of the point of intersection of the longitudinal centre plane, AB, of the truck with the axis of the steer axle. b)For trucks without an articulating axle or with axle locks or stabilizers in use: the centre of the point of the area of contact between the test platform surface and
38、 another wheel or stabilizer pad. When the truck rating is related to the use of stabilizers, suspension locks, etc., such devices shall be used during tests. If the truck can also be used without their engagement, an additional test shall be carried out in this condition. 4.3.3Test load The test lo
39、ad shall have a mass equivalent to the maximum load, Q, that the truck can elevate to its maximum lift height acting through the centre of gravity, G, nominally positioned at the standard load centre distance, D, as indicated on the capacity plate of the truck both horizontally from the front face o
40、f the fork arm shank and vertically from the upper face of the fork arm blade (see Figure 1 and Table 1). When additional lift heights, loads and load centre distances are to be indicated on the capacity plate, the truck shall meet the requirements established by the tests specified in this part of
41、ISO 13563 for these additional ratings. The centre of gravity, G, of the test load shall be located on the centre plane between the mast uprights.

This may be achi
44、eved by application of parking or service brakes which can be secured in the “on” position, or by wedging the wheels against the truck frame, ensuring however that the articulation is not affected. Blocks (chocks) with a maximum height not exceeding the value indicated in Table 2 may be used, if nec
45、essary, to maintain the initial position of the truck on the test platform or slope. Blocks (chocks), if used, shall not artificially improve stability.

47、 20). By means of a plumb line or other suitable equipment, set the mast vertical. Elevate the fork arms and specified test load to approximately 300 mm above the test platform. With the front face of the fork arm shank vertical, establish a point, E (see Figure 18) on the fork arm or fork carrier h
48、aving a fixed relationship to the centre of gravity, G, of the test load (see Figure 1). This point E shall be used to provide a reference datum, F, on the test platform (see Figure 18). When the mast is elevated, a new point F1on the test platform may occur (see Figure 19). By the following adjustments this new point F1can be returned to the original location F (see Figure 20). For trucks with tiltable masts, changes in the location of F1shall be corrected by varying the tilt of the mast within the limits provided by the design of
