測定装置。 This is a furnace wall tube thickness measuring device that remotely and automatically measures the thickness of furnace wall tubes in boilers, etc., in which an ash removal tool and an inspection tool are attached to a beam that can support the load, and are wrapped around the winch. A cable wire is extended from near the top of the boiler to near the bottom, and the wire is slanted in a substantially dogleg shape with respect to the furnace wall tube, and stretched so as to be tensioned in both directions at the top and bottom. Features: Furnace wall tube thickness measuring device.
