Comfort posture and position of push-pull operation of the sagittal plane in standing

Abstract

Push-pull operation is often used in daily work and life. The position of the operating lever, the grab bar, handrail, and the buckle slot is one of the main factors that affect the push-pull task performance. Through the test analysis of 30 people’s push and pull task, the comfort movement ranges of the elbow joint and the shoulder joint, as well as the acceptable height ranges of hand in the sagittal plane were obtained. The research results demonstrated some practical applications for the comfort evaluation of single light load push-pull operation and the ergonomics evaluation of the general manual control layout and position.
