Tandem RTC-80160s Work on Toronto Expressway
The Frederick G. Gardiner Expressway is an 18 km east-west expressway running alongside Lake Ontario in Toronto, Ontario. The Strategic Rehabilitation Plan by the City of Toronto will revitalize the 62-year-old expressway in multiple phases. The contractor for the first phase of the project is using bridge building methods (like pre-fabrication) to accelerate construction and lessen noise and environmental impact.
Two 145 t Link-Belt RTC-80160 Series II rough terrain cranes were used last summer to lift and remove existing steel and concrete expressway deck sections and replace with new fabricated deck panels. The new concrete deck panels lifted in tandem weigh between 45 to 100 t and span 20 to 42 m.
Phase 1 included complete replacement of steel girders and concrete for existing on-ramps and road decking between Lower Jarvis and Cherry streets. Poured-in-place deck panels were built on-site east of Cherry street in quality and climate controlled canopies. Approximately 400 sections of deck panel were constructed and lifted into place, and the Link-Belt rough terrain cranes were part of the fleet performing the rehabilitation.
Initial construction of Phase 1 included westbound lanes and ramps, requiring 2 open lanes in each direction for commuter traffic. Crews primarily worked 24/7 to accelerate the project and reduce the length of construction. In roughly 8 months, the contractor has logged 1,200 hours on both RTC-80160 Series II.
