On top of this AGV, there is a jacking mechanism, by which it carries the dolly and drives to the predetermined position. Its loading capability of large size dolly in small space is what the normal AGV can't do in the limited logistics space (where there is many obstacles and space is narrow). In addition, it can move laterally when the double steering wheels turn in right angle, which further saves the turnover space of the stations along the lineside and realizes the automation of line-feeding at one go. This model fits for the heavy parts and materials. It is the first AGV with a load of over 2 tons in China.
