本标准的目的是规定一项附加试验，用于验证装有动力负载处理装置（如侧移装置）的满载卡车的稳定性，侧移装置可将重心从卡车纵向中心平面移动到相当大的预定范围。在这种模式下，此类装置用于在桅杆垂直或提升至最大起重臂角度和伸展度的情况下沉积和回收负载。

The objective of this Standard is to specify an additional test for verifying the stability of a laden truck fitted with a powered load-handling device, such as a sideshift, which can displace the centre of gravity to a substantial, predetermined extent from the longitudinal centre plane of the truck. Such devices are used in that mode for depositing and retrieving a load with the mast vertical or raised to maximum boom angle and extension.
