Closing the Gate

The lock gates for the third set of locks (expansion) on Panama Canal basically consist of two orthotropic steel plates (skins) held apart by truss structures and plates forming the compartmented buoyancy chamber that, when submerged, reduce the operational weight carried by two rolling wagons. These steel structures, as large as 187 by 105 by 33 feet, are supported by an upper wagon, running on rails situated in the gate recess, and a lower wagon, running on rails situated in the lock chamber. The gates are opened and closed by drive systems consisting of cables, winches, and sheaves.
