Spreader beams power historic lift

A 308t historic lift of WWII dry dock gate was Lifted from the Brisbane River, Australia  using Modulift below-the-hook spreader beams.

Modulift spreader beams have played a pivotal role in an extraordinary lift in the Brisbane River, Australia, where East Coast Cranes and Tutt Bryant Heavy Lift and Shift successfully removed a historic World War II-era dry dock gate weighing 308t.

Using a MOD 400 and two MOD 250 spreader beams in a 1-over-2 rig configuration, East Coast Cranes and Tutt Bryant Heavy Lift and Shift achieved a lift never attempted since the gate’s installation in the 1940s.

A lift of historic proportions

The dry dock gate, measuring 37m wide and 14m high (with 10m submerged), has a rich history. Forgacs Dry Dock, the second largest in Australia, was a key hub for wartime ship repair, accommodating Panamax-class vessels and serving Pacific submarines during WWII. Post-war, it was utilised for shipbuilding and infrastructure projects.

Remarkably, the gate had no original lifting points or precise weight specifications, making the lift an engineering feat. Adding to the challenge, the gate held approximately 180t of water as ballast and was located beneath Brisbane Airport’s flight path.

Precision engineering with Modulift’s spreader beams

In such high-stake projects, Modulift’s versatile spreader beams demonstrate their engineering competence. The MOD 400 was deployed at a 16m span, while the two MOD 250 beams operated at 4m spans each. Together, they distributed the load evenly, ensuring optimal stability and safety throughout the lift.

Sarah Spivey, managing director at Modulift, commented, “Seeing our spreader beams used in projects of this scale and historical importance highlights the global trust in our engineering solutions. Customers across the globe can access the MOD system quickly for critical heavy lifts like this.”

A legacy preserved

This operation not only underscores the adaptability of Modulift’s lifting solutions but also celebrates the legacy of the Forgacs Dry Dock. As a centrepiece of Australia’s maritime history, the successful removal of the gate sets the stage for potential restoration or repurposing.
