Abstract
The invention relates to a device for tilting and turning coke-oven doors for the purpose of maintenance and repair. It comprises a door-receiving support frame with upper guide rollers, which are guided in a guide rig having parallel rail pairs. At the lower end of the support frame a firmly connected drive device engages, which is movable on a raised horizontal rail track. The drive device pulls the support frame from the vertical into the horizontal position and pushes it back into the vertical position. The guide rig includes a vertical part and an inwardly extending part contiguous thereto. The center between the guide rig on the coke side and the guide rig on the machine side is interrupted. The rail pairs end at the bottom in sturdy stops for the guide roller. The invention is thus an accident proof tilting device, with sufficient space for repair purposes being available on the working platform.
