A heavy duty carriage cart is provided, which is used when moving a heavy object. The heavy object can safely be moved without being influenced by factors which obstruct the traveling of the carriage cart, such as distortions or joints of flooring material on a floor surface. In a lower part of a carriage cart main body, front rollers are pivotally supported by a front shaft, rear rollers are pivotally supported by a rear shaft, and intermediate rollers are pivotally supported by an intermediate shaft at a wheel base of the rollers. A load receiving platform, having a planar portion which is freely movable while contacting with the bottom of the heavy object, is placed on an upper part of the carriage cart main body. Four heavy duty carriage carts are used to move the heavy object. |
