PURPOSE:To facilitate a series of works such as a digging work, a stone laying work, etc. by allowing the left and right car bodies consisting of a crawler frame and a main frame to be expanded in width by an operation of an oil hydraulic cylinder so that the mounting of a work machine and the loading of a cargo can be selectively performed. CONSTITUTION:A self-propelled bogie 1 is constituted with a car body 2, a traveling device equipped on the car body 2, and an expanding device 8. The car body 2 is divided into the left and the right, and a pallet 4 capable of being equipped with a flat frame (not shown in the figure) for mounting a work machine and loading a cargo is provided on the upper frame 6 of each car body 2. The left and right car bodies 2 are connected with beams 8a, 8b, 9 slidably supported at both ends against each car body 2 so that the width can be expanded or shrunk by an operation of a hydraulic cylinder 11. Therefore, a work machine can be mounted while both car bodies 2 are expanded in width and a cargo can be loaded while they are shrunk in width. |
