Lin­den Co­mansa in Mon­treal’s New Cham­plain Bridge

NBM&CW - - EQUIPMENT & MACHINERY -

A tower crane model 21LC550 is work­ing on the construction of the main py­lon of this in­fra­struc­ture, which will re­place the dam­aged Cham­plain Bridge, Canada’s busiest in traf­fic

Opened in 1962, the Cham­plain Bridge in Mon­treal, is one of the city’s main road links and Canada’s busiest bridge, with an av­er­age of 136,000 cross­ings per day. Due to the ex­treme cli­mate con­di­tions in Mon­treal, as well as the use of road salt on the pave­ment, the bridge is suf­fer­ing a pro­gres­sive de­te­ri­o­ra­tion that dif­fer­ent main­te­nance and repair plans have not been able to stop. Thus, the Cana­dian Gov­ern­ment de­cided to build an­other bridge as a re­place­ment.

Since 2015, the Sig­na­ture on the Saint Lawrence Group, formed by SNC-Lavalin, ACS, and HOCHTIEF, is work­ing on the construction of the New Cham­plain Bridge, lo­cated par­al­lel to and a few me­tres away from the ex­ist­ing bridge, which is still open to traf­fic. The new bridge will fea­ture a spec­tac­u­lar 170-me­tre tall main py­lon (558 ft), which is be­ing built with the sup­port of a Lin­den Co­mansa 21LC550 crane.

The crane ar­rived at the job­site in early September 2017 and was erected on the deck of the bridge with a height un­der hook of 67.8 me­tres. When the work of the crane ends, the crane will be 180 me­tre tall (591 ft) from the base of the py­lon, 123 me­tres (403 ft) from the deck of the bridge. Mon­treal’s 21LC550 has max­i­mum load ca­pac­ity of 25 tonnes (55,120 lb), to lift large pre­cast con­crete struc­tures and heavy form­work panel. An­other ver­sion of this crane is avail­able with max­i­mum load of 20 tonnes (44,090 lb).

The works at the New Cham­plain Bridge are ex­pected to fin­ish by December 2018.
