Abstract
An apparatus and method enabling safe removeal of the drum head of a coking drum. The invention provides an apparatus remotely placing a carriage under the drum head and the carriage is adapted to remotely engage the drum head, tightly support the head against the drum while workers are in the area, and to lower the head and carry it away. Included in the system is a safety feature wherein the carriage is normally supported by springs which in the event of excessive load automatically transfers the load carrier to an overhead beam designed to carry any excessive loads.
