合理确定车辆使用寿命和检修周期,是车辆修造的一项重要政策。当前,车辆部门正在对这个问题进行广泛的讨论。笔者认为,敞车占我国货车的63％,而现在钢木结构敞车已经停止生产,旧的小型敞车已在逐步淘汰,全钢敞车正在大批新造并已成为我国敞车的主要车型,合理确定全钢敞车使用寿命和检修周期尤为重要和迫切。 Reasonable determination of vehicle service life and maintenance cycle, vehicle construction is an important policy. Currently, the vehicle department is extensively discussing this issue. In my opinion, gondola cars account for 63% of China’s trucks. Now that the gondola cars have stopped producing, the old small gondola cars have been gradually phased out. A large number of new gondola cars are being newly built and have become the major models of China’s gondola cars. Life cycle and maintenance cycle is particularly important and urgent.
