A b s t r a c t Cleaner for the sealing surfaces of levelling doors and levelling door frames of horizontal chamber coke ovens This cleaner is for use on a coke-pushing machine. Basically, the cleaner comprises a substantially channel-section steel plate casing (11) movable towards the levelling door frame (3) and back, the casing side walls extending around the levelling door frame (3); and one guideway (13, 13a) each is provided near the side walls and each such guide- way extends in a first portion parallel to the levelling door frame (3) over substantially the same length as the latter and, in a following second portion, parallel to the lateral sealing strips of the upwardly opening levelling door (6). A truck (15) movable in the guideways (13, 13a) carries liquid nozzles (19, 22) directed at the sealing surfaces (4) of the levelling door frame (3) and the sealing surfaces (5) of the levelling door (6), the nozzles being connected by way of flexible lines (23, 24), such as pressure hoses, to an appropriate supply of high pressure liquid. The nozzles (19, 22) are subdivided into two groups and are so controlled that when the levelling opening (1) is passed over, only the outer nozzles (19) directed at the sealing strips are operative. The truck (15) is driven by a pressure- - 13 - medium-operated actuator (27) in association with two gas compression springs (33, 33a). (Fig. 1)
