Research of Operating Posture of Shoulder-Mounted Equipment

The purpose of this paper is to increase the scientificalness of shoulder-mounted equipment operator's training. A research on shoulder-mounted equipment operator's body force stress in standing and kneeling positions qualitatively points out that operator should strengthen the training of some body parts. Training these relative parts is of much pertinence to improve the training effect. Based on the simplified model of human body and static analysis method, the main stressed parts in two different training states are found-in standing position and in kneeling position. In this way, the methods of how to strengthen the training after confirmed the main stressed parts of operator in different training states are pointed out. The main stressed parts of shoulder-mounted equipment operator in standing and kneeling positions are presented, and corresponding training methods provide strong support for operator's scientific training.
