PROBLEM TO BE SOLVED: To provide a self-propelled carriage which comprises crawlers and driving wheels and can be easily collected when it becomes immovable due to failure, battery exhaustion, fuel shortage, or the like.SOLUTION: A self-propelled carriage comprises a vehicle body having crawlers 2 or driving wheels and traveling on a floor surface L, driven wheels 8 provided in the vehicle body, and a lifting mechanism for raising and lowering the driven wheels 8. The lifting mechanism lowers the driven wheels 8 to the lower side of the vehicle body and lifts the vehicle body so that the crawlers 2 or the driving wheels float from the floor surface L. The lifting mechanism is operated by a power source supplied from the outside of the vehicle body, which is different from a power source for operating the vehicle body.SELECTED DRAWING: Figure 1
【課題】クローラや駆動輪を備えた自走式台車において、故障やバッテリ切れ燃料切れ等により移動不能になった場合にも容易に回収することができる自走式台車を提供する。【解決手段】クローラ2もしくは駆動輪を備えて床面Lを走行する車体と、車体に設けられた従動輪8と、従動輪8を昇降させる昇降機構と、を備え、昇降機構は、従動輪8を車体の下方へ下降させて、クローラ2もしくは駆動輪が床面Lから浮くように車体を持ち上げるようになっており、車体を作動させるための動力源とは別の、車体の外部から供給される動力源で作動する構成とした。【選択図】図1
