PURPOSE:To make a mobile bogie self-travel in a smooth and agile way under control within a pit recessed on a working floor, improve workability and ensure safety by projecting only the upper part of the bogie from the slit of a floor plate and providing a ramp and a turntable for supporting the carried article. CONSTITUTION:A mobile bogie Tr is so provided as to be movable on a carriage passage 2 within a recessed pit Pi on a working floor F. And only the upper part of a bogie frame 4 is projected from the slit 3 of a floor plate 1 covering the pit Pi and a ramp 8 and a turntable 9 for supporting a carried article are provided. According to the aforestated constitution, the carriage passage 2 can be so arranged as to minimize an effect by an obstacle on the ground and the movable bogie Tr can always be made to travel in a smooth and agile way without any ingress and adherence of dusts in the pit Pi. Furthermore, when the carried article on the turntable 9 is assembled and otherwise processed, the work can be done easily. In particular, workability at the underside of the carried article is improved and that high safety can be ensured.
