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.

- opening the vessel by moving the head laterally while simultaneously raising the first section of the head and lowering an opposite section of the head;
- and
- closing the vessel by moving the head laterally while simultaneously lowering the first section of the head and rasing the opposite section of the head.
