PROBLEM TO BE SOLVED: To provide a roller table for carrying a ladle, which has elevation type stoppers for preventing the drop of the ladle, and of which the stoppers smoothly work so that hindrance to operations due to the failure of the stoppers does not occur. SOLUTION: The roller table for carrying a ladle is provided with stoppers 27a, 27b, which ascend/descend by the driving force of an air cylinder 28 or a hydraulic cylinder and prevent the drop of the ladle loaded on the roller table with the stoppers in an ascending position. The stoppers, at all times, receive force acting in an ascending direction produced by springs 34, 34. The springs assist the driving force in an ascending direction, which is produced by the air cylinder or the hydraulic cylinder. COPYRIGHT: (C)2006,JPO&NCIPI
