摘要

重复使用手持式螺母滚轮会导致装配操作员患上肌肉骨骼疾病(MSD)。使用工具的组织通过自己公司的特定方法和建议来控制螺母滚轮造成的物理接触。本研究旨在探讨一家汽车企业在对螺母滚轮的使用进行人体工程学评估时的现行做法。代表汽车制造企业内不同专业角色的 14 名员工接受了采访,了解了他们参与螺母转轮人体工学评估的情况和方法。研究结果表明,拧紧扭矩和工具类型等客观标准与操作员对负载的主观评估相结合,可识别与使用螺母紧固器相关的 MSD 风险。这样,工作姿势等因素的影响也可纳入评估。此外,研究还发现,信息和知识的可获得性可能会影响由此得出的暴露估计值,例如,有关如何适当选择工具设置的信息并不容易获得。通过深入了解汽车制造商管理和评估手持拧紧工具的方法,政策制定者可以为螺母拧紧器的反应负荷暴露标准化评估制定推荐的限制和方法。

An assembly organization's approach to conducting ergonomics assessments of nutrunners in the absence of standards

Repetitive use of handheld nutrunners contributes to the development of musculoskeletal disorders (MSDs) among assembly operators. Tool-using organizations control the physical exposures resulting from nutrunners through their own, company-specific methods and recommendations. The aim of this study was to explore an automotive organization's current practice when conducting ergonomics assessments of nutrunner use. Fourteen employees representing different professional roles within the automotive manufacturing organization were interviewed about their involvement in, and approaches to, ergonomics evaluations of nutrunners. Findings show that the objective criteria tightening torque and tool type are combined with the operators' subjective assessments of the load to identify MSD risks associated with nutrunner use. This way, the effects of factors such as working posture could be integrated into the assessment. Further, it was found that information and knowledge availability could influence the resulting exposures estimates, where for example information about how to appropriately select tool settings is not readily available. In addition, there are negotiating criteria such as quality considerations which need to be balanced with health and safety management, influencing the physical demands associated with power tools.

Relevance to industry

By providing insight into an automotive manufacturer's approach to managing and assessing handheld tightening tools, policy-makers can form recommended limits and methods for standardized assessments of reaction load exposure from nutrunners.
