I appeared on the market through a variety of light agricultural vehicle dump body and the lifting of a more detailed understanding, confirmed the light compartment and the lifting of agricultural dump body design, a better solution to the design of a dump truck and the problem of higher manufacturing costs for production and modification of the production truck with a new idea. In this paper, the design features of the dump truck, as well as the development of the status quo at home and abroad to do an overview of the relevant. Then, from inside the design of the lifting body design, hydraulic system design aspects of the design truck EQ3040B. Among them, the inside design of the main form and automatic opening and closing body design, the design of lifting mechanism of the lifting mechanism for the motion analysis and force analysis, and then in the hydraulic system design, its working principle are described by come up with a reasonable calculation of the hydraulic device. Finally, Vice-frame dump truck has been designed.Key words：Dump truck; Compartment; Sub-frame; Lifting mechanism; Hydraulic systemII
