Modulift Spreader Beams Power Historic 308-Tonne Lift in Brisbane River

Modulift spreader beams played a critical role in an extraordinary engineering feat in the Brisbane River, Australia, where East Coast Cranes and Tutt Bryant Heavy Lift and Shift removed a historic World War II-era dry dock gate. The massive gate, weighing 308 tonnes and submerged for decades, was successfully lifted using a MOD 400 and two MOD 250 spreader beams in a 1-over-2 rig configuration.

The dry dock gate, measuring 37 meters wide and 14 meters high (10 meters of which were submerged), was part of the Forgacs Dry Dock, Australia’s second-largest dock. This site played a pivotal role in World War II, repairing Panamax-class vessels and Pacific submarines. Post-war, it served Australia’s maritime and infrastructure industries.

The lift presented significant challenges due to the absence of original lifting points, lack of precise weight data, and the 180 tonnes of water ballast within the gate. Its location beneath Brisbane Airport’s flight path added to the complexity, requiring precise coordination and execution.

The MOD 400 beam was set at a 16-meter span, while the two MOD 250 beams were configured with 4-meter spans. This configuration ensured even weight distribution, optimal stability, and safety during the high-stakes lift.

Sarah Spivey, Managing Director at Modulift, remarked:“Seeing our spreader beams utilized in projects of this magnitude and historical importance highlights the trust placed in our engineering solutions worldwide. The MOD system’s adaptability ensures customers have access to critical heavy-lifting tools when needed.”
