Modulift for modular

3 September 2019

Canadian modular building company Tilt Wall Ontario is using Modulift spreader beams for the construction of a new condo apartment block on the Muskoka Bay Resort in Gravenhurst, just north from Toronto.

The project involved the construction of a five storey multi-unit residential condo building with a sixth storey on the three stair towers for access to the roof. The building was constructed entirely with 381 precast tilt-up concrete panels. The panels’ width ranged from 1.5m (5ft) to over 18m wide with weights anywhere from 1t to 58t.

Modulift’s local distributor, Equipment Corps supplied an MOD 50 and an MOD 110. Project manager Ken VanCasteren said: “We utilised two different-sized beams and between the two, they were used for about 80 to 85% of the picks. We did not adjust the lengths of the beams during the lifting process but instead used the two different beam sizes to allow for quicker rigging changes. From the MOD 110, we went down to an eight-point pick for load distribution and on the MOD 50 we were using a four-point lifting set up.”

A Liebherr LG 1750 lattice boom mobile crane was used for this project, with the added assistance of a 350t mobile crane to help move some of the concrete panels closer to the LG 1750 for final picking and setting.

The LG 1750 carefully lifted the panels horizontally to the required height and then tilted them upright into place by sliding the wire rope links through the snatch blocks attached to the spreader beam. The Tilt Wall Ontario team then braced the panels until the permanent structural connections were completed.
