Twin Trolleys for 910 ton segment transport

Main span erection of New Bridge on St. Lawrence River

City of Montreal – CANADA

The two trolleys have a rack and sprocket driving system.
They run on the bottom flange of an H-shaped beam under already assembled segments.
Their duty is to move new segments to cantilever end, where lifting structures are positioned to complete the sticking sequence.

EDIlab developed trolleys design: concept, calculations, production assistance, on site assembly and personnel training.
