Abstract: A device for the removal of a coke-oven door, engaging the door frame of a coking chamber by one or more swingable latch arms that are axially loaded by Belleville springs, comprises a support carrying one or more unlatching heads alignable with the swing axes of respective latch arms along which that body can be moved toward and away from the door by a hydraulic jack linked with a fixed or separately movable base. Each unlatching head comprises a gripper rod axially movable inside a pressure sleeve by means of a hydraulic actuator. The gripper rod has a pair of claws which, when that rod is brought into contact with a knob on a pivot stud of the associated latch arm, are cammable into engagement with this knob by a forward thrusting of the pressure sleeve through the hydraulic actuator. The sleeve then comes to bear upon a collar surrounding the pivot stud whereby an extension of this collar compresses the Belleville springs behind the latch to relieve their pressure upon that arm.
