Montréal called on the performance of Liebherr

The Olympic Stadium of Montréal, Canada, has chosen the two Liebherr tower crane 630 EC-H and 710 HC-L partnering together to perform the extensive renovation of Montréal Tower and refurbish its observatory and the state-of-the-art of lighting.

To renovate Montréal Tower, one the country’s most recognizable buildings, contractor Pomerleau was teamed up with Liebherr’s North-American dealer Morrow to deliver a machine that could meet the high requirements of the complex $ 40 million project where safety concerns and controlling cost overruns are of primary importance.

The tower crane 710 HC-L was the most suitable for this project, an outperforming all other tower cranes in its class, with a maximum loading of 141,000 lbs (64,000 kg) and hoisting line speeds up to 577fpm (176m/min). To let the crane stands at the appropriate spot, a hole in the canvas of the roof had to be made, while the second crane the hammerhead 630 EC-H has been secured to the building using extended custom struts.

These two cranes are the highest in Canada and could be visible at a distance of up to 12.5 miles (20 km).
