<p>PROBLEM TO BE SOLVED: To provide a telescopic carriage bogie in which the length of a load-carrying platform can be easily changed corresponding to the size, the volume, etc. of a cargo.SOLUTION: In a telescopic carriage bogie 1 which comprises a load-carrying platform 2 that comprises front wheels 7 and rear wheels 5 and can travel with a cargo loaded on an upper surface and a handle 3 that is provided at the rear side of the load-carrying platform 2, the load-carrying platform 2 is constituted through being divided into a load-carrying platform front half part 2b and a load-carrying platform rear half part 2a facing to each other. Each of the load-carrying platform front half part 2b and the load-carrying platform rear half part 2a includes at least two longitudinal frames which are arranged with a specified spacing in the lateral direction orthogonal to the traveling direction and extends in the travelling direction, and the longitudinal frames of one side of the load-carrying platform front half part 2b and the load-carrying platform rear half part 2a are inserted into the longitudinal frames of the other side, so as to be configured as telescopic in the traveling direction. The length of the load-carrying platform 2 in the traveling direction is adjustable and can be locked as a specified length by a lock mechanism 8.</p> |
