Modulift beam aids LTM 11200-9.1 in Quebec

A Modulift spreader beam was used beneath the hook of the largest mobile crane manufactured in serial production in the world (LTM 11200-9.1), at the Turcot Interchange, a three-level stack freeway project in Quebec, Canada. Turcot Interchange is a hub for road traffic in the Montréal area, interconnecting highways 15, 20 and 720, in addition to facilitating access to the Champlain Bridge. It is also an essential road link between Montreal-Pierre-Elliott Trudeau airport and downtown Montréal. A crucial phase of the project was installation of two girders, weighing 200,000 pounds apiece.

The MOD 110H beam, which can lift up to 170 tons at 37 feet, was used at its maximum 59 feet in length, as the 1,200-ton capacity Liebherr LTM 11200-9.1 was utilized with 194 feet of main boom and 445,300 pounds of counterweight to lift a girder into position. The crane was supplied by rental firm Guay Cranes and the rigging gear by Modulift’s Canadian distributor Equipment Corps Inc.

The LTM 11200-9.1, which worked at a 95-foot radius, combined with a 300-ton capacity Sany SCC8300 crawler crane, but not in tandem lift, as such. Below the hook of the crawler crane a custom beam lifted the second girder and, once connection to the other one was complete, both cranes could release the load simultaneously. Synthetic slings completed the rigs on both cranes.

“We frequently supply lifting and rigging gear to the project but this was a standout lifting operation,” said Luke Habza, national sales and development, Equipment Corps. ”Combined with the MOD 110H beam, use of the Liebherr amounted to thousands of dollars-worth of savings to the customer, who didn’t need to mobilize another crawler crane, as would be typical for this kind of application.”

“The LTM 11200-9.1 is the largest, strongest, telescopic mobile crane worldwide, which is manufactured in serial production,” said Wolfgang Beringer, sales promotion, Lliebherr-Werk Ehingen GmbH. ”The LTM 11200-9.1 was launched at Bauma Munich in 2007. In 2014, we celebrated delivery of the 50th unit, at which point the cranes were already in use all over the world. The LTM 11200-9.1 was delivered to Guay Cranes in 2011.”

Beringer explained that the main advantage of a telescopic boom crane versus a lattice boom crane is set-up time, as the lattice sections have to be bolted on the ground. This requires more space compared to a telescopic crane. The transportation volume of a lattice boom crane is also bigger, he added.
