It has both ordinary bills, and transportation function of car with a crane hookon loading and unloading function; Besides can finish this vehicle goods of loading and unloading besides, still can finish between the car and car cargo handling. Therefore, using the accessory lifting transporters, can greatly improve transport efficiency, reduce the transportation cost, reduce fatigue strength, security work safety, so in recent years to get bigger development. The accessory lifting transporters have good hoisting capacity and transportation capabilities, a lightweight, rapid, economic and other advantages, so for the accessory van modified is very important and useful. In this design is mainly to the lifting device design, calculation, selection and checking and calculating the performance of modified vehicle. Lifting device is hubei chengli automobile Co., LTD. Is the production of finished products through calculation and completion of the crane selection and adapted to the vehicle performance after the analysis and checking. Also completed the design of hydraulic device, calculation, selection, the choice and other category chassis design calculation of some accessories. By dongfeng little overlord category chassis EQ1032T51DJ3 type chassis, according to the p
