The Netherlands-headquartered Mammoet has released its Focus 30 crane, which has been developed specifically for use in tight and confined workspaces.
With large, industrial facilities becoming increasingly crowded and city areas more congested, Mammoet determined that a new lifting solution was needed to better support clients. The Focus 30 is a 2,500-tonne lifting capacity crane that can be assembled in the smallest footprint possible, allowing more work to continue around it than would be the case for a crawler crane.
The crane has a 30 m x 40 m footprint and its boom system is assembled vertically in sections. This has a number of safety benefits as it ensures no part of the crane overhangs buildings, plant or people during assembly and disassembly activities. This process takes 14 days.
The compact footprint also allows customers to complete more work alongside heavy lifting operations, while its low ground bearing pressure limits the impact on surrounding infrastructure and reduces the amount of civil work that is required for lifting to begin.
The crane’s variable and splittable superlift system enables it to be relocated swiftly, offering increased flexibility for operators. It can also be moved entirely to another lifting position without having to be deconstructed.
Jacques Stoof, global director market development and innovation at Mammoet, explained: “The Focus 30’s ability to operate around key site infrastructure means refineries and chemical plants do not incur the typical loss of production while upgrades are made. That means projects are completed quicker and with a lower total cost of refurbishment.
“Similarly, with real estate at such a premium in the world’s cities, all available land is built upon and underground infrastructure can prevent the use of heavier lifting cranes. The Focus 30’s small footprint and low ground bearing pressure reduces disruption and helps civil engineers keep our busy, expanding megacities running smoothly.”
The crane boasts a 30,000-tonne/m load moment and a low ground pressure of 6 tonnes per sq m. Mammoet added that the unit has a large and variable operational window, allowing more lifts to be made using the same crane.
Further models in the Focus range are planned. The first crane will shortly undertake its inaugural project in North America.
