Contractors need to be able to count on reliable and durable construction equipment when building large structures – they know that technical failure and downtime can lead to delays and higher costs.

From dams on the River Nile to new sports stadiums in the Amazon, equipment manufacturers and contractors are working to ensure large projects stay on schedule.
As well as general earthmoving and lifting machinery, specialised construction equipment models are available to tackle big projects. Falsework and formwork manufacturer Doka, for instance, has launched new specialised formwork just for dam construction, while XCMG teamed up with Chinese petrochemical company Sinopec to develop a huge 4,000 tonne capacity crawler crane for extreme lifting jobs.
The XGC88000 crane made its debut lift at the Wanhua Industrial Park in Yantai, China, where it was tasked with hoisting a 118 m tall, 1,680 tonne propylene production tower into place. The crane’s 108 m boom and 33 m fixed jib were used in a 30 m operating radius.
XCMG said the tower was erected onto its construction base within four hours. It described the lift as a breakthrough in the development of super-tonnage crawler cranes.
Developing the machine is one thing, but delivering it onto a remote construction site is another question entirely. Co-ordinating the movement of materials and equipment around a large structure jobsite can be a major challenge, and a highly organised approach is crucial to keep things moving efficiently.
In South America, for instance, equipment from Terex and its sister brand Genie is supporting construction of the final stages of the 45,000 seat Arena da Amazonia Stadium in Manaus, the capital of the Brazilian state of Amazônia.
Set to host four matches during next year’s FIFA World Cup, the stadium is being built by a trio of contractors – Andrade Guitierrez, ENTEC, and Tomiasi – and was designed by GMP Architekten.
The stadium’s most striking feature is its self-supporting roof, construction of which is currently underway. Made from over 200 pieces of steel and weighing over 6670 tons (6500 tonnes), the roof structure will consist of mutually supporting cantilevers with steel hollow core girders. The largest individual components are 22 m long and weigh 30 tons (27 tonnes). Continue reading “Large structures: Tackling the extremes” »
