ISO 3691-2:2016给出了安全要求，并对其进行验证的手段，用于自动推进的工业可变牵引车和可变达的集装箱搬运车/达到ISO 5053-1（以下简称卡车）定义的堆垛机，装备具有用于正常工作职责的叉或整体式装载处理装置（例如叉臂或装置，例如吊具，用于处理容器）。 它不适用于 - 粗糙地形可变拖车， - 用于处理集装箱的粗糙地形可变拖车， - 主要用于土方移动的机器（例如装载机和推土机），即使当铲斗和铲斗用叉子代替时， - 负载可以从各个方向自由摆动的机器。 为了ISO 3691的这一部分的目的，叉臂和集成附件被认为是卡车的一部分，而安装在载货架上或用户可拆卸的叉臂上的附件/设备则不是。然而，文件也给出了对这些附件的要求。 在ISO/TS 3691-7和ISO/TS 3691-8中讨论了符合ISO 3691本部分规定的任何区域要求。 ISO 3691-2:2016涉及附件B所列的所有重大危险，危险情况或危险事件

ISO 3691-2:2016 gives safety requirements and the means for their verification for self-propelled industrial variable-reach trucks and variable-reach container handlers/reach stackers as defined in ISO 5053‑1 (hereafter referred to as trucks), equipped with forks or integral load-handling devices for normal industrial duties (e.g. fork arms or means, such as spreaders, for handling containers). It is not applicable to - rough-terrain variable-reach trucks, - rough-terrain variable-reach trucks for handling containers, - machines designed primarily for earth-moving (e.g. loaders and dozers), even when their buckets and blades are replaced with forks, - machines from which the load can swing freely in all directions. For the purposes of this part of ISO 3691, fork arms and integrated attachments are considered to be a part of the truck, whereas attachments/equipment mounted on the load carrier or on the fork arms which are removable by the user are not. Nevertheless, requirements for such attachments are also given by the document. Any regional requirements additional to the provisions of this part of ISO 3691 are addressed in ISO/TS 3691‑7 and ISO/TS 3691‑8. ISO 3691-2:2016 deals with all significant hazards, hazardous situations or hazardous events, as listed in Annex B, with the exception of the following, relevant to the applicable machines when used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. It does not establish requirements for hazards that can occur - during construction, - when using trucks on public roads, - when operating in potentially explosive atmospheres, or - when lifting persons.
