To improve work efficiency while ensuring the safety of workers even when the work position at the work site is in a relatively narrow and confined space.SOLUTION: A work bench 23 comprises: a plurality of divided floor members 26 forming a work floor 25 on its upper surface and movable in contraction and expansion directions including a contraction direction to contract a floor area of the work floor 25 from a first floor area which is the maximum floor area, to a second floor area, and an expansion direction to expand the floor area from the second floor area to the first floor area; a moving mechanism 28 performs a work floor expansion/contraction operation to expand/contract the work floor 25 in the first and second directions by moving the plurality of divided floor members 26 overlapping each other to contract the work floor 25 in the first and second directions so as to cause the floor area of the work floor 25 to become the second floor area, as well as, by moving the plurality of overlapping divided floor members in the expansion direction so as to cause the floor area of the work floor 25 to become the first floor area; and a control unit 30 that causes the moving mechanism 28 to execute the work floor expansion/contraction operation.SELECTED DRAWING: Figure 2

    【課題】作業現場の作業位置が比較的狭い狭空間であっても作業員の安全性を確保しつつ作業効率を向上させること。【解決手段】作業台23は、その上面で作業床25を形成し、作業床25の床面積が最大床面積となる第1の床面積から第2の床面積に縮小させる縮小方向と、第2の床面積から第1の床面積に拡大させる拡大方向とを含む拡縮方向に移動可能な複数の分割床部材26と、作業床25が第2の床面積となるように、複数の分割床部材26を縮小方向に重なり合うように移動させて作業床25を第1の方向と第1の方向と第2の方向に縮小させると共に、作業床25が第1の床面積となるように、重なり合った複数の分割床部材を拡大方向に移動させて作業床25を第1の方向と第2の方向に拡大させる作業床拡縮動作を行う移動機構部28と、移動機構部28に作業床拡縮動作を実行させる制御部30と、を備えている。【選択図】図2
