Description of the Related Art Conventionally, when a cylindrical body is transported by a trackless unmanned transport vehicle (hereinafter simply referred to as a "transport vehicle"), if the transfer vehicle is not equipped with a transfer device, the cylinder is moved onto the transport vehicle. When transferring the body, it is necessary to use a transfer device such as a crane, so the transfer vehicle must be on standby until the transfer onto the transfer vehicle by this transfer device is completed. There was a problem that the operation rate of the bogie was reduced.

Therefore, as shown in FIG. 7, a lift-up device 4 for vertically moving a V-shaped saddle 3 that supports a cylindrical body 2 is installed on the upper surface of a transport trolley 1, and the lift-up device 4 is raised. As a result, the one that receives the cylindrical body 2 placed on the skid 5 fixed on the ground from the skid 5 comes out.

Japanese Unexamined Patent Publication No. 49-112314 proposes a configuration in which the inclination angle of the V-shaped saddle 3 can be changed so that various things can be conveyed. Further, by making the interval between the V-shaped saddles 3 changeable, one that can cope with various diameters and widths is available.
No. 20 is proposed. Japanese Utility Model Publication No. Sho 56-3221 proposes a device capable of preventing a lateral displacement of a conveyed object by interposing an elastic member in the V-shaped saddle 3.
