According to China39。s environmental sanitation information s statistical analysis and calculation of urban garbage, at present our country has reached million tons annual, and with growing at 8 per cent a year. Meanwhile, China39。s urban garbage collection and transportation capacity is obviously deficiencies, sanitation vehicle quantities are far from reach construction ministry urban environment, sanitation standards CJJ 272021 car/million prescribed standards. Allocation Now urban population, if 375m according to standard requirements, quantities gap, but current vehicles a 40 percent more than 80% are overworked, cannot satisfy the actual needs. Thus, the city garbage every year in demand, and in more than 13,000 car increasing year by year, subject involves the sealed truck belongs to the new special vehicle to its own environmental protection in our country has good have widely application. This paper introduces the design of miniature sealed truck that describes in the design process on the problems and solutions, for different structure parison, garbage sealedbid rational selection, and design a second chassis sealed carriage and hydraulic lifting mechanism, choose the correct hydraulic cylinder to ensure the normal operation of lifting mechanism. Keywords: Miniature Sealed Truck。 Sealed Carriage。 Special Vehicle。 Hydraulic Lifter。Tipping i 目 錄 摘要 ........................................................................................................................................
