摘　　要：According to the present situation that the current road wrecker with a large occupied volume is mainlytowed by truck and cannot be applied to car clearing on the congested or narrow road, based on the structure ofexisting electric pallet truck, a small sized road wrecker is designed, which has some advantages such as smallvolume, convenient to use and flexible operation. The main structure, hydraulic system and working principle aredesigned and illustrated in this paper. The optimization design of mechanism multi-objective function for scissorslifting device is carried out by using MATLAB optimization toolbox, and installation position parameters of hydrau-lic cylinder is optimized by using optimization design concept, which decreases the maximum output force of hy-draulic cylinder and reduces the energy consumption of hydraulic system, and provides a reliable basis for the im-provement design of this kind of small sized road wrecker.According to the present situation that the current road wrecker with a large occupied volume is mainly towed by truck and cannot be applied to car clearing on the congested or narrow road,based on the structure of existing electric pallet truck,a small sized road wrecker is designed,which has some advantages such as small volume,convenient to use and flexible operation.
