Here the motivation was, principally, water supply problems but also to effect a quicker passage of vessels, as those going in opposite directions could pass in the lock. The caissons—always submerged, as at Combe Hay —were without bottoms and were arranged so that their sides dropped into deep underwater channels formed by "minor walls ...
Commercial traffic now bypasses the old lifts and is handled by the enormous Strépy-Thieu boat lift, whose rise of 73m was the highest in the world [citation needed] upon completion. Following an accident in January 2002, in which a malfunctioning elevator began rising as a motor barge was exiting, lift no. 1 was taken out of service ...
The Peterborough Lift Lock is a boat lift located on the Trent Canal in the city of Peterborough, Ontario, Canada, and is Lock 21 on the Trent-Severn Waterway. For many years, the lock's dual lifts were the highest hydraulic boat lifts in the world, raising boats 65 ft (20 m). This was a considerable accomplishment in the first years of the ...
Anderton Boat Lift – diagram of original hydraulic configuration (not to scale) The Trustees asked their Chief Engineer, Edward Leader Williams, to draw up plans for a boat lift. He settled on a design involving a pair of water-filled caissons that would counterbalance one another and require relatively little power to lift boats up and down.
The Kirkfield Lift Lock is a boat lift located in the city of Kawartha Lakes, Ontario, Canada, near the village of Kirkfield. It is designated "Lock 36" of the Trent–Severn Waterway , situated at the highest section of the canal (256.2 m). [ 1 ]
