Abstract

The invention relates to a cargo loading-unloading device, in particular to a mother-child type loader-unloader. The mother-child type loader-unloader comprises a load-bearing mother machine and a movable child machine, wherein the load-bearing mother machine is provided with a traveling device, and the movable child machine is arranged on the load-bearing mother machine. It is defined that the front portion of the load-bearing mother machine faces toward the depth direction of a cargo container during usage. Rails for the movable child machine to move front and back are arranged on the load-bearing mother machine. The rails are in the same plane with the bottom surface of the inner side of the cargo container during usage. A crane and a crane guide beam extending forwards and backwards are arranged at the top of the movable child machine. The crane guide beam is provided with an overhang section overhanging forwards. A cargo passage is arranged on the rear portion of the load-bearing mother machine and communicates with the movable child machine from top to bottom when the movable child machine moves in place. The left side(s), the right side(s) and / or the back side(s) of the load-bearing mother machine and / or the movable child machine are provided with cargo openings in communication with the cargo passage. According to the mother-child type loader-unloader, a lifting device does not need to be arranged in the cargo container, the precious space in the cargo container is not occupied, and the cargo loading-unloading device is wide in application range, high in adaptability and convenient to use.
