Mammoet has strategically placed a giant Liebherr LR 13000 lattice-boom crawler crane to complete several lifts from a single location—making the project’s lifting process more efficient.
The LR 13000 is designed to lift up to 6.6 million pounds (3,000 metric tons), offer hoisting heights to 803 feet, and reach out to a maximum radius of 656 feet.
The LR 13000 was used to safely install two reactors in a Gulf Coast polypropylene plant undergoing an expansion. The crane will place more large components while working from the same location—saving time and space for other work taking place within the plant.
To set the two reactors, the LR 13000 features 315 feet of boom and is configured with its derrick and suspended ballast attachment—providing a total lift capacity of up to 1,500 tons.
The smaller of the two reactors weighed 500 tons. The larger reactor weighed 750 tons, stood 160 feet tall, and was set at a radius of 110 feet.
One of Mammoet’s Demag CC2800 crawler cranes worked as a tailing crane during both reactor lifts.
The LR 13000’s high capacity will let it make the upcoming lifts from the same location. For those lifts, the crane will have 315 feet of boom plus 236 feet of jib (551 feet total).
Scheduled for completion in the first quarter of 2020, the expansion will increase the polypropylene plant’s production capacity by 450,000 tons per year.
