Tower crane takes shape at New Champlain Bridge site

The tower crane helping build Montreal’s New Champlain Bridge has been erected to its initial working height.

The Linden Comansa model 21LC550 tower crane is working on the construction of the 170m-tall main pylon of the new crossing that will replace the busy Champlain Bridge.

Signature on the Saint Lawrence Group – made up of SNC-Lavalin, ACS and Hochtief – began work in 2015 building the New Champlain Bridge a few metres away from the original structure.

The crane arrived on site last month and was erected on the bridge deck with a height-under-hook of 67.8m. By the time the 21LC550’s work ends, the crane will be 180m tall from the base of the pylon, 123m from the deck of the bridge.

Montreal’s 21LC550 has maximum load capacity of 25t to enable it to lift large precast concrete structures and heavy formwork panels. Another version of the crane is available with maximum load of 20t.
