PURPOSE: To safely and smoothly move a loading apparatus assembled with a refractory testing furnace without using a crane, etc., in a short time.

CONSTITUTION: A side frame 18 of a loading receiving frame B formed in a gate shape is placed on main and sub rail members 14 and 15 respectively provided at both sides of a furnace body 11, a frame member 27 for supporting wheels 29 is rotatably coupled to the frame 18 via a support shaft 28, the wheels 29 are pressed to rail surfaces by a reaction when the frame 18 is pressed by a hydraulic jack 30 provided at the member 27, the shaft 28 is raised by the reaction at the time of pressing, the frame 18 is floated, and the wheels are driven by a motor 31 to move the frame B. Thus, a receiver having a large weight to become a reaction receiver at the time of loading can be moved without using a crane.
