Conveniently located for visitors to the coming 2012 Olympic Games, the new shopping mall stands at the heart of today’s busy construction site. With teams of different trade specialists working in close quarters, the crane’s proximity to the building was was limited due to jobsite safety considerations.

The furthest of 10 unit lifts was carried out in luffing fly jib configuration (SFSL) at an astonishing 128.5-meters radius with 10-tonne load, including hook block and lifting tackle. The remaining lifts were carried out on a luffing jib configuration with fixed main boom (SWSL).

Assembled within a three day period, the Terex TC 2800-1 was configured with 72-meter main boom and 160-tonne counterweight, plus 72-meter luffing fly jib extension fixed at a 15° radius. Significantly increasing lifting capacity and reachable radius, the set-up also included a 30-meter superlift mast and 300-tonne superlift counterweight.

 

“The new Westfield Shopping Mall complex is a core component of the Olympic development project and access to the building is very restricted. Working to a tight schedule, we needed to move in, handle our far-reaching lifts efficiently and safely, dismantle and move out fast to leave room for other teams in just seven days,” says Mr. Steve Wathen, Commercial Director, Heavy Cranes Division, Ainscough Crane Hire Ltd. “In addition to its outstanding reach capacity and lifting performance, the truck mounted design, compact dimensions and straightforward assembly of the TC 2800-1 were also great benefits that worked very well for us on this highly challenging job.” 

Driven directly onto the construction site via temporary roadways, the heavy Terex TC 2800-1 had to meet the 6-tonne per meter ground pressure jobsite requirements.  This was accomplished by deploying its 14 x 14-meter, X-type outriggers on Ainscough’s extra large 7.5 x 2.2-meter heavy-duty outrigger mats to reduce ground bearing pressure to 5.6 tonnes per square meter - a very low figure for a crane of this size.
