在最近的十年间,在改善机保车结构和改进冷却系统方面进行了大量工作。在保证车辆货物间稳定的合理温度工况方面的现代化要求导致必须重新考虑车体结构,即过渡到制造能保证必要的强度和气密性的全金属承载车体,采用较好的结构材料和其他等。由于采用了新的底架和地板结构、铝制压型的地板格子,改进了电气和制冷设备,减轻了机器间隔热结构的重量,货物间内顶板采用了铝合金及其他措施,使机保车自重减轻3吨多,为38.5～39吨。这可使车辆的名义载重量相应地提高到43吨。此时每延米
In the recent decade, a great deal of work has been done on improving the structure of the van and improving the cooling system. Modernization requirements that ensure a stable, reasonably-temperature condition between vehicle loads lead to the need to reconsider the structure of the vehicle body, ie transition to the manufacture of all-metal load-bearing bodywork that ensures the necessary strength and airtightness, using better structural materials and other Wait. As a result of the new chassis and floor structure, aluminum pressure-type floor grids, improved electrical and refrigeration equipment, reducing the weight of the thermal structure between the machine room, the cargo room between the roof with aluminum and other measures to machine security Vehicle weight to reduce more than 3 tons, 38.5 to 39 tons. This allows the nominal load of the vehicle to be correspondingly increased to 43 tons. At this time every meter
