R&D Crane Delivers Major Toronto Bridge
Cherubini Bridges and Structures has completed work on the Four Signature Bridges contract for Toronto’s Port Lands project. The job wrapped up in style with the company successfully orchestrating a complex 4-crane pick to get the final 446.6 t segment of the bridge sent up the St. Lawrence River by barge.
The lift of the 22.3 m-wide, 57.1 m-long Cherry Street North Bridge was performed by R&D Crane, a division of Cherubini Group. It was completed using the 4 largest cranes in its fleet: a Manitowoc Model 16000 lattice-boom crawler, and Grove GMK6400, GMK5250L, and GMK5240 all-terrain models.
The cranes combined to lift the structure from its supports in the yard in Dartmouth, Nova Scotia, allowing a self-propelled modular transporter (SPMT) with transfer beams and a huge Cherubini-engineered turntable to take the load.
The need to bring together the 4 cranes was an engineering solution to help ensure the bridge was positioned as smoothly as possible at its final resting place.
“There were space restrictions which meant we couldn’t just simply roll on and roll off the barge using the self-propelled transporters alone. Because of the this, we engineered a solution that supplied the sections to the jobsite on a turntable structure – our giant ‘Lazy Susan’, explained Darren Czech, Cherubini Group CEO. “This allowed tugboats in Toronto to spin them around on the barge in the middle of the harbor, ideally positioning them to slot right into their final resting place. So, we used the 4-crane pick at our yard to make sure the section was accurately placed on the turntable ahead of shipping to Toronto.”
