Leaves the following points to be solved. At the lifter 10, it is necessary to raise and lower while supporting the cylindrical object 1 which is a heavy object, and the ascending / descending amount is relatively large and the ascending / descending time is long. Power consumption for lifting and lowering by the lifter 10 is large and economically disadvantageous. In the stopper 22, the rolling distance to the trolley 24 varies depending on the operating position of the stopper 22 and is affected by the inertial force at the time of rolling to prevent the cylindrical object 1 from being excessively transferred, and thus, the accuracy is improved. It is difficult to stop the carriage 24 at any time, and it is necessary to consider a special device etc. for surely stopping the rolling of the carriage 24, and the device is likely to be complicated.
