Liebherr’s 630 EC-H and 710 HC-L tower cranes help expand the Montréal Olympic Stadium

    During the extensive renovation in Canada, the Montréal Olympic Stadium is hosting the Liebherr tower crane models 630 EC-H and 710 HC-L that are visible at a distance of up to 12.5 miles (20 km), both working together to renovate the Montréal Tower, one of the country’s most recognizable buildings. The tower cranes are being used for the addition of office space, a refurbished observatory and state-of-the-art lighting. Extended custom guyings were used to secure the 630 EC-H high-top tower crane to the building. From 2018 on, the renovated building will accommodate more than 1,000 employees of its new tenant Desjardins.

    This important and highly recognized project led the construction contractor Pomerleau to team up with Liebherr’s North-American dealer Morrow – asking them to deliver a machine that could meet the high requirements of the complex $40 million project where safety concerns and controlling cost overruns is of primary importance.

    The 710 HC-L model tower crane was the perfect machine to accomplish this project. Outperforming all other tower cranes in its class, it has a maximum load of 141,000 lbs (64,000 kg) and hoist line speeds up to 577 fpm (176 m/min). A hole in the canvas of the roof had to be made to let the crane stand at the appropriate spot. The second crane on the site, the hammerhead 630 EC-H has been secured to the building using extended custom struts.
