Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a working table having a pair of legs to constitute a stepladder and a base plate, with which sideways movement is made practicable by furnishing caster devices to enable flotation of the working table only on the condition that no operator is on and the caster devices are arranged as not constituting any obstruction for going up and down the legs or working around the legs. SOLUTION: Legs 2 and 3 constitute a stepladder, and a corner member 10 is installed by welding at each inside corner formed from the undersurface of each end of the undermost cross-bar 7 and the inner surface of a column 6 on each side. The corner member 10 is provided with a caster mounting part 13 rigidly, and therto a caster 9 is attached. The corner member 10 works as a brace as conventional meaning, which is therefore no more needed and interference with the caster 9 can be avoided. |
