标准摘要
[中文适用范围]: 本文件规定了一项额外的测试,用于验证满载卡车的稳定性,该卡车的使用创造了特殊的操作条件,即负载重心基本上偏离卡车的纵向中心平面或设计的中心位置。 如果位移超过以下情况,则认为负载严重偏移: ——对于额定容量 < 5000 kg 的卡车,100 毫米; ——150毫米,额定载重量≥5000kg且≤10000kg的卡车; ——250毫米,适用于额定载重量> 10000 kg且< 20000 kg的卡车; ——350 毫米,适用于额定载重 ≥ 20000 公斤的卡车。 本文件适用于 ISO 5053-1 中定义的以下类型的卡车: a) 平衡重卡车; b) 前移式和跨运式卡车; c) 托盘堆垛机; d) 双向和多向卡车; e) 工业可变前移卡车; f) 带桅杆的越野卡车; g) 崎岖地形可变前移卡车; h) 具有铰接转向装置的平衡重卡车; i) 可变范围集装箱装卸机; j) 平衡式集装箱搬运机; k) 订单拣选卡车; l) 回转式越野可变前移卡车。 [外文原描述]: This document specifies an additional test for verifying the stability of a laden truck whose utilization creates the special operating condition whereby the load centre of gravity is substantially offset from the truck's longitudinal centre plane or from the centred position by design. A load is considered to be substantially offset if displaced by more than: — 100 mm, for a truck with a rated capacity < 5 000 kg; — 150 mm, for a truck with a rated capacity ≥ 5 000 kg and ≤ 10 000 kg; — 250 mm, for a truck with a rated capacity > 10 000 kg and < 20 000 kg; — 350 mm, for a truck with a rated capacity ≥ 20 000 kg. This document is applicable to the following types of trucks as defined in ISO 5053 - 1 : a) counterbalance trucks; b) reach and straddle trucks; c) pallet stackers; d) bidirectional and multidirectional trucks; e) industrial variable-reach trucks; f) rough-terrain trucks with mast; g) rough-terrain variable reach trucks; h) counterbalance trucks with articulated steering; i) variable-reach container handler; j) counterbalanced container handler; k) order-picking truck; l) slewing rough-terrain variable-reach truck.
