A ship elevator includes a channel, having an inclined bottom, interconnecting two bodies of water at different levels, a water wedge terminating baffle movable along the channel, and driving means moving the baffle. The water wedge engaging face of the baffle is inclined from the vertical so that the upper edge of this face is forwardly of the lower edge thereof, considered in the direction toward the water wedge. The baffle is supported from the driving means by a pair of arms which are articulated to the baffle about generally upright pivots and are articulated to the driving means about generally horizontal pivots, and a lift cable arrangement is provided for lifting the baffle from the channel to allow passage of ships therebeneath. The driving means includes driving members movable along rails on the bank of the channel and including a rack and pinion drive, with the rack teeth extending vertically. |
