Installation of new gates at Lock No. 9 of the Chambly Canal
Chambly Canal National Historic Site
The installation of the four gates of Lock No. 9 on the Chambly Canal turned out to be a spectacular operation! They arrived at night by convoy (under police escort for part of the journey given their unusual shape) directly from Saint-Augustin-de-Desmaures, where they were designed in the workshop. Then, the gates were installed using a crane on their lower pivot in the lock.
Did you know? The new lock gates for Lock No. 9 are made primarily from British Columbia Douglas fir and white oak. Each door weighs more than 5 tonnes, the weight of an adult elephant. These are arched doors, which means, the two leaves lean against each other to form a "V". This concept, which dates back to Leonardo Da Vinci, ensures that the pressure of the water keeps the doors closed.
