If a wireless remote control device is mounted on the slide wagon 1, the slide wagon 1 can be operated wirelessly. In addition, since the motor 11 is driven only at the start and end of the movement of the slide wagon 1, if a mechanism for selectively switching the meshing gear train is provided, the motor 11 can also be used, for example. It is.

Further, the outer cover 2 and the inner frame 3 are provided integrally, and when the movement of the slide wagon 1 starts and ends, for example, the wheels 4 and the casters 41 move back and forth to the bottom surface of the slide wagon 1. Or the legs are provided in the lifting mechanism, and the wheels 4 and the casters 41 are separated from the stage or brought into contact with the stage by moving the legs to the bottom of the slide wagon 1. It may be.

In the above embodiment, the steering mechanism and the elevating mechanism are configured to be driven by the motors 10 and 11, respectively. However, the present invention is not limited to this, and may be operated by an operator. The configuration of the lifting mechanism is not limited to the above embodiment. Of course, the driven truck 30 of the above embodiment is used.
Alternatively, any one of a drive mechanism and a steering mechanism may be selectively added.
