In 2007 the Government of Qatar awarded a contract to Singaporean-based Keppel Seghers to design and build the world’s largest fully integrated waste to energy (WTE) plant. At the same time, the Men From Marr’s were designing what would become the world’s largest tower crane – the M2480D – and the two projects came together in what would be a game changing moment for the heavy lift industry.
Faced with the challenge of how to lift and install mechanical components within a heavily congested construction area, the problem with big crawler cranes (the traditional approach) is they take up a lot of room on the ground, often necessitating shutting large sections of the construction site down.
Although Keppel Seghers had a tower crane in mind as the solution, the crane for the job didn’t yet exist. But as luck would have it, Marr’s was designing a super-size heavy lifting crane that would supersede the need for big crawler cranes on large-scale construction projects similar to the WTE plant.
With a greater lifting capacity of 330 tonnes, the M2480D took up less room on the ground and eliminated the issue of onsite congestion caused by managing heavy lifts from multiple locations by allowing lifts from the site perimeter. The result for Keppel Seghers was a 30-50% lift in productivity.
In 2007, the Government of Qatar awarded an AU$1.8 billion contract to Singaporean-based Keppel Seghers to design and build the world’s largest fully integrated waste to energy (WTE) plant in Doha. Faced with the challenge of how to lift and install mechanical components within a heavily congested construction area, Keppel Seghers had a tower crane in mind as the solution.
Backtrack to 1999, when Transfield was constructing a hydroelectric power station near Canberra in NSW, Australia and needed a solution for lifting heavy project components over a dam wall. We built the M1280D to do the heavy lifting in one lift, negating the need for the existing ‘pass the parcel’ series of cranes that were in place. It became the world’s biggest tower crane
At the time we received a call from Keppel Seghers for help on the WTE plant in Doha, we’d identified a market for something even bigger than the M1280D and were working on the design for the M2480D. It was the perfect, but yet unbuilt and untested, solution for our client’s problem. When we built the first M2480D it became a game changing moment for the project – and the heavy lift industry
12-months later we had built the crane in Australia and shipped it to Doha. With the M2480D doing all the heavy lifting from the perimeter of the site, there was no longer any need to shut down parts of the construction site. Productivity increased by 30-50%.
18-months later the WTE was completed, and Marr’s team had successfully managed the cranage operation from the other side of the world without incident or any downtime. The crane returned to Australia scratch-free and a backlog of orders and additional four M2480Ds either built or under construction
Let's talk about how we could add value to your project
We work with our clients to find a solution that works – no matter how big or complex the job is. And if the right crane doesn’t already exist, we’ll build one to suit the needs of your project.
