PURPOSE:To obtain a door lifter for coke oven, surely carrying out attaching and detaching operations, formula excellent operating efficiency, wherein an outer frame is hung on a lift frame and the lift frame is oscillated by a hydraulic cylinder to make the inclination of a door and the lift frame same. CONSTITUTION:In a door lifter wherein the door lifter is hung on a door lifter frame 1 in the vertical direction and supported on both edges of the top and the bottom, the door lifter consists of an outer frame 2 and a lift frame 3 made as an inner frame of the outer frame, the lift frame 3, at the upper part, is supported and hung on a shaft 5 attached to a lifting hydraulic cylinder 7 fixed to the outer frame 2 and, at the lower part, is connected in action to an inclina tion adjuster 8 similarly fixed to the outer frame 2. Attaching and detaching of a door 4 of coke oven is surely carried out by the door lifter which is constructed to adjust the inclination angle of the lift frame by oscillating the lift frame 3 around the shaft 5 by operation of the inclination adjuster 8.
