过去的罐车和漏斗车,只有单程装载货物,返回时大多是空车,运用极不经济。新货车底架中部设有装运粉粒货物的罐体,其前后部则安设输送液体的罐体。通常在发车时,装载粉粒状货物(如水泥),返回时,则装载液体原料或液体燃料(如重油),使车辆能在往返途中得到有效使用。图示,在车底架1中央安设装运粉粒货物的罐体3,其下部装有漏斗2,罐体3的前后部安设液体罐体4和5,前后罐体在罐体3的下部两侧有三角形
In the past, tankers and hopper trucks were loaded with goods only one way and were mostly empty when returned. Their use was extremely uneconomical. In the middle of the new truck chassis, there is a tank for transporting the cargoes of powder and granule, and the front and back of the tank are provided with tanks for transporting liquid. Normally at the time of departure, loading of granular cargo (such as cement) will load liquid raw materials or liquid fuels (such as heavy oil) on return so that the vehicle can be effectively used on its way to and fro. 1, a tank 3 for transporting powder and granular cargoes is arranged at the center of a car chassis 1, a hopper 2 is arranged at the lower part of the tank 3, liquid tanks 4 and 5 are arranged at the front and the back of the tank 3, The lower part of the triangle
