Abstract：The cars lift and traverse move in the no-steering state were designed for the traverse will be parked in the narrow space of the car.After another application of the shape and size of car-related improvements,the device is installed the caster and hydraulic cylinder lifting reasonably to realize the lateral movement by manpower ,through the principles of human forklift and jack lift. The overall design of one facility equipment for cars traverse move were introduced. Based the design of key mechanism, the strength analysis of correlative components was presented. The analysis results demonstrate that, the equipment can satisfy the design request, and low cost，have structure stability, operate in brief, maintenance convenience, high safety and advantage of unloading gearing.
