10、ures described in 3.2. For trucks with a rated capacity up to and including 10 000 kg, the tilting platform test shall be used to verify stability in the event of a dispute. 3.2 Verification procedure 3.2.1 Tilting platform A test platform shall be used which can be tilted about one side. The truck
11、being tested for stability is placed on the initially horizontal test platform For counterbalanced fork-lift trucks, the position of the truck on the test platform shall be as for test number 3 of IS0 1074:1991. The test conditions shall be in accordance with the requirements of IS0 1074. For reach
12、and straddle fork-lift trucks, pedestrian and rider controlled, the position of the truck on the test platform shall be as for test number 3 of IS0 3184:-. The test conditions shall be in accord- ance with the requirements of IS0 3184. For pallet stackers and high-lift platform trucks, ped- estrian
13、and rider controlled, the position of the truck on the test platform shall be as for test number 3 of IS0 5766:1990 The test conditions shall be in ac- cordance with IS0 5766. The test shall be conducted to the side to which the truck is least stable. The mast shall be retracted and tilted fully rea
14、rward where the design permits The test load (3.3) shall be displaced laterally in the direc- tion of least stability to the fullest extent allowed by the mechanism and raised to the maximum elevation The test platform shall be tilted slowly to the slope specified in test number 3 of IS0 1074.1991,
15、IS0 3184.-, or IS0 5766:1990, as appropriate for the type of truck. The truck is considered stable if it does not overturn under the conditions of the test. For the purposes of this test, the onset of overturning is considered to occur at that test platform slope which, if increased, would cause ove
