研究调查了某地区４个火车站搬运作业工人的作业特点，劳动休息制度、劳动负荷及健康状况等。铁路搬运作业采用＂三班两运转＂轮班制度，工人劳动过程中负荷量较大，且主要是弯腰和转身这类易造成腰部损伤的动作，调查结果表明搬运工人的腰痛人数明显高于对照组，应加强劳动组织和劳动保护，以保障工人健康和提高工作效率。 The study investigated the operational characteristics, labor rest system, labor load and health status of the workers handling the four railway stations in a certain area. The “three shifts and two shifts” shift system is adopted for the handling of railways. The workload of workers in the process of labor is relatively large. The main reasons are the actions of bending over and turning around which can easily cause waist injury. The survey results show that the number of low back pain patients is significantly higher than that of the control In the group, labor organization and labor protection should be strengthened in order to protect workers’ health and improve work efficiency.
