Claims

[Scope of utility model registration request]

A scale-shaped in-furnace work gondola that is movable in the height direction and lateral direction of the boiler for maintenance and inspection of the four-sided side wall in the boiler furnace of a thermal power plant, etc., and is installed above the boiler side wall, There are multiple openings through which horizontal main ropes with vertical main ropes are hung to take safety belts for crew members, and wire ropes passed into the furnace from two of these openings, allowing for emergency evacuation of crew members. A gondola with an open upper part, a stabilizing weight suspended below, and a control box for adjusting the winding of the wire rope, and a mounting pin fitted to the center of the gondola serve as a fulcrum. and a pair of winches attached to the left and right sides of the outer frame, and the wire rope is engaged with each winch to suspend the gondola in the furnace. A wire-controlled gondola for working inside a furnace.
