人类工效学. 人工搬运. 第1部分: 提升、降低和运送

[中文适用范围]： 本文件规定了手动提升、降低和搬运的建议限制，同时考虑了任务的强度、频率和持续时间。 它旨在提供有关评估多个任务变量的要求和建议，从而评估工作人群的健康风险。 本文件适用于手动搬运质量为 3 kg 或以上的物体以及中等行走速度，即在水平表面上的 0.5 m/s 至 1.0 m/s。 本文件基于 8 小时工作日，但也涵盖更长的工作时间，最长可达 12 小时。 它还解决了一天中轮班中组合提升、降低和搬运任务的分析。 本文件不包括在坐着时握住物体（不行走）、推或拉物体或手动搬运。 本文件的其他部分涵盖了物体的推和拉，不包括处理人或动物。 （有关搬运人员的更多信息，请参阅 ISO/TR 12296。 ）本文件不涉及使用外骨骼等提升辅助设备时手动提升物体的问题，也不涉及孕妇或残疾人的需求。 [外文原描述]： This document specifies recommended limits for manual lifting, lowering and carrying while taking into account the intensity, the frequency and the duration of the task. It is designed to provide requirements and recommendations on the assessment of several task variables, allowing the health risks for the working population to be evaluated. This document applies to manual handling of objects with a mass of 3 kg or more and to moderate walking speed, i.e. 0,5 m/s to 1,0 m/s on a horizontal level surface. This document is based on an 8 h working day, but also covers more prolonged working times, up to 12 h. It also addresses the analysis of combined lifting, lowering and carrying tasks in a shift during a day. This document does not cover the holding of objects (without walking), the pushing or pulling of objects or manual handling while seated. The pushing and pulling of objects are covered in the other parts of the ISO 11228 series. This document does not cover handling people or animals. (For further information on handling people, refer to ISO/TR 12296.) This document does not address the manual lifting of objects while using lift-assistive devices such as exoskeletons and does not address the needs of pregnant women or persons with disabilities.
