A coke guide machine includes a shuttle car carried by rails on a coke bench for a battery of coke ovens. Movable along the shuttle car is a carriage having two support stations that are rotatable about a common vertical axis. The support stations include scissor arms that form extendible support devices, one of which carries a handling device for a coke oven door and the other carries a device adapted to clean exposed sealing surfaces of an emptied coking chamber. The carriage also supports a coke guide including an extendible section to bridge an open passageway wherein an inspection car moves along the coke bench between the shuttle car and the coke ovens. A door cleaning machine is positioned in a stationary manner on the shuttle car to clean a coke oven door carried to it by the door handling device after 180.degree. rotation by the support station and movement of the carriage along the shuttle car in a manner to concurrently align the opened coking chamber with the device adapted to clean exposed sealing surfaces thereof.
