Right-angle power-tools (RAPT) employed in automotive manufacturing promote greater productivity and quality fastenings, as well as, improve process efficiency. Due to RAPT technological advances automotive manufactures desire to understand their ergonomics consequences within a laboratory environment, however, laboratory-based representation must accurately represent the real world. A survey within automotive assembly plants was conducted to capture RAPT operation data. After examining 80 total RAPT operations, we logged the 3D locations of the fastener location (with respect to the operator), direction and the hand placement location used by operators. Four common locations with respect to the midpoint between the ankle (in cm; X = sagittal plane, Y = transverse plane, Z = coronal plane): 1) 2, 113, 62; 2) 42, 104, 45; 3) -26, 151, 36; 4) -37, 92, 52. These locations can be used to simulate RAPT operations within a laboratory. The survey provided insight into current workstation layout when operating RAPTs and, knowledge for laboratory-based RAPT examinations so that simulated tasks best represent their operation in automotive manufacturing.

汽车制造中采用的直角电动工具 (RAPT) 可提高生产率和紧固件质量，并提高流程效率。由于 RAPT 技术的进步，汽车制造商希望在实验室环境中了解他们的人体工程学后果，然而，基于实验室的表示必须准确地代表现实世界。在汽车装配厂内进行了一项调查，以获取 RAPT 操作数据。在检查了总共 80 次 RAPT 操作后，我们记录了紧固件位置的 3D 位置（相对于操作员）、方向和操作员使用的手放置位置。相对于踝关节中点的四个常见位置（以厘米为单位；X = 矢状面，Y = 横向面，Z = 冠状面）：1) 2, 113, 62; 2) 42、104、45；3) -26, 151, 36; 4) -37, 92, 52. 这些位置可用于模拟实验室内的 RAPT 操作。该调查提供了对操作 RAPT 时当前工作站布局的深入了解，以及基于实验室的 RAPT 检查的知识，以便模拟任务最能代表他们在汽车制造中的操作。
