を特徴とするレール走行式炉内作業用足場。 This is a scaffold for working inside the furnace, where multiple stages of scaffolding are erected in the height direction of the boiler for maintenance and inspection of the four-sided side walls inside the boiler furnace of thermal power plants, etc., and is installed on shaped steel laid horizontally at the bottom of the furnace. A plurality of rails are installed at appropriate intervals, and a reinforcing material that forms the lowest stage of scaffolding is placed in a direction perpendicular to the track of these rails and close to the side wall of the object to be inspected. In addition to attaching as many wheels as possible, a pulley is movably suspended from multiple wire ropes stretched parallel to the rail track through an opening in the upper part of the side wall, and a fixing wire hanging from the pulley is attached to the top stage. A rail-running scaffold for working in a furnace, characterized in that the scaffold is locked at an appropriate position.
