The unheading device includes a cover unit (14) for attachment to a lower flange of a coking drum (10), fastening means (20) by which a plurality of swing bolts are disconnected by remotely operated detensioning equipment, and a frame device (16) which can lower the cover unit and moves it on a carriage unit laterally to one side. A chute (15) attached to the frame can be raised into engagement with the coking drum lower flange for removal of coke from the drum. Following such coke removal, the chute is lowered and the cover unit is moved laterally and remotely reconnected to the coking drum lower flange.
