Abstract
A coke drum head is hinged to a coke drum body using a compound joint such as a trammel pivot, and the head is moved between open and closed positions using an actuator. In moving between open and closed positions, the head traces out a non-circular path which reduces the required headroom relative to a head using a standard pivot.
