美国国家职业安全与健康研究所 (NIOSH) 提升方程 这是职业健康与安全专业人员用于评估手动搬运任务相关肌肉骨骼损伤风险的工具。它针对特定任务计算出推荐重量限制(RWL),该数值代表健康工人可安全搬运的最大重量,不会增加下背部损伤风险,同时考虑了任务几何参数和频率等因素。.

The revised NIOSH lifting equation from 1991 provides a more comprehensive risk assessment than its 1981 predecessor. The core of the method is the calculation of the Recommended Weight Limit (RWL) using the formula: [latex]RWL = LC \times HM \times VM \times DM \times AM \times FM \times CM[/latex]. In this formula, LC is the Load Constant (51 lbs or 23 kg), which is the maximum recommended weight under ideal conditions. The other terms are multipliers, each with a value between 0 and 1, which reduce the allowable weight based on deviations from these ideal conditions. These multipliers are: HM (Horizontal Multiplier), VM (Vertical Multiplier), DM (Distance Multiplier), AM (Asymmetric Multiplier), FM (Frequency Multiplier), and CM (Coupling Multiplier). For example, the further an object is held from the body (increasing the horizontal distance), the smaller the HM value becomes, thus lowering the RWL. The equation also allows for the calculation of a Lifting Index (LI), where [latex]LI = \frac{Load Weight}{RWL}[/latex]. An LI greater than 1.0 indicates that the task is high-risk for some fraction of the workforce, and redesign should be prioritized. An LI of 3.0 or more is considered highly hazardous. The equation is a cornerstone of physical ergonomics, providing a quantitative, evidence-based method for evaluating and mitigating one of the most common causes of workplace injury.
