PROBLEM TO BE SOLVED: To secure a working scaffold promptly by forming an elevation type scaffold apparatus equipped with means laterally moving at right angles with the flow direction, and provided with carriages being movable in the flow direction on working floors, and also set with crossing scaffolds via sliding means on the carriages. SOLUTION: A pair of elevation type scaffold systems 2 provided with an elevation driving apparatus 3 are installed in its upper parts with working floors 4, and laterally moving means 5 utilizing wheels are set at the frame part. Rails 7 are put on the working floors 4, and four sets of carriages 9 placed with wheels 8 capable of traveling on the rails 7 are mounted thereon, and crossing scaffolds 11 are framed at right angles with the flow direction of production on rotation rollers 10 as sliding means put on the carriages 9. During carrying in and out an electric device 1, the working floor 4 is made higher than an overall height dimension of the electric device 1 by the elevation driving apparatus 3, which an inner width W between the working floors 4 is expanded by the laterally moving means 5, and an inner length L between the crossing scaffolds 11 is also expanded by manual, and further, during the working period, a height of the working floors 4 are adjusted so that the inner width W and inner length L are made correspond to the electric device 1. This can secure a height place working scaffold adapted to an assembly line production method promptly without the use of a crane system.
