Inclinometry and video analyses can provide objective measures of physical workloads. The study aim was to measure and observe arm, back and head postures and movements among forklift truck operators (FLTOs) during a working day, analyzing differences between types of forklift trucks and to assess reported workload and health. Twenty-five male FLTOs in a high-level warehouse were randomly included. The data collected comprised technical measurements, video analyses of postures and movements, and a questionnaire measuring health, pain and workload. On average, the FLTOs rotated their head more than 45°, in total, 232 times/h. Video analysis revealed that FLTOs periodically drive the forklift truck sideways with the head rotated in the direction of travel, and in periods look upwards, in which the head is highly rotated and extended. Inclinometry and observations during the working day has the potential to be a valuable part of risk assessment promoting occupational safety and health.

测斜仪和视频分析可以提供物理工作量的客观测量。该研究旨在测量和观察叉车操作员 (FLTO) 在工作日期间的手臂、背部和头部姿势和运动，分析叉车类型之间的差异，并评估报告的工作量和健康状况。25 名男性 FLTO 在高层仓库中被随机纳入。收集的数据包括技术测量、姿势和动作的视频分析以及测量健康、疼痛和工作量的问卷。平均而言，FLTO 的头部旋转超过 45°，总计 232 次/小时。视频分析显示，FLTO 定期将叉车侧向行驶，头部沿行驶方向旋转，并且在周期向上看时，头部高度旋转和伸展。
