To enable, an extendable dolly and a conveyance system having the same, efficient use of space by decreasing an installation space for the extendable dolly, workability improvement with no unnecessary movement for extension and, furthermore, lower cost of equipment.SOLUTION: An extendable dolly 100 configured so as to be extendable and that increases/decreases a placement area for a load by extending/narrowing, comprises: a main dolly portion 1; an auxiliary dolly portion 2 coupled to the main dolly portion 1 so as to be movable, that defines the placement area together with the main dolly portion 1, and increases/decreases the placement area by moving apart from/closer to the main dolly portion 1; and a coupling mechanism portion 3 for coupling the main dolly portion 1 and the auxiliary dolly portion 2. The coupling mechanism portion 3 is configured such that the auxiliary dolly portion 2 is separated from the main dolly portion 1 by an action subjected to the auxiliary dolly portion 2 from a load (pallet 5) conveyed into the placement area.SELECTED DRAWING: Figure 2

    【課題】伸縮台車及びそれを備えた搬送システムにおいて、伸縮台車の設置スペースを小さくしてスペースの効率的な使用を可能とし、伸縮させるための無駄な動作を生じさせることなく、作業性を向上させ、しかも、設備費用を安く抑えることを可能とする。【解決手段】伸縮可能に構成され、伸張・収縮することで積載物の載置領域を拡大・縮小させる伸縮台車100であって、主台車部1と、主台車部1に対して移動可能に連結され、主台車部1とともに載置領域をなし、主台車部1に対して離間・近接することで載置領域を拡大・縮小させる補助台車部2と、主台車部1及び補助台車部2を互いに連結する連結機構部3と、を備え、連結機構部3は、載置領域上に搬入された積載物(パレット5)から補助台車部2が受ける作用によって補助台車部2を主台車部1に対して離間させるように構成されている。【選択図】図2
