The biggest crane ever erected in London is now ready to start work at the Earls Court development.
The AL.SK190 crane, designed and built by specialist engineering firm ALE has a maximum safe lifting capacity is 4,300 tonnes, making it the largest capacity lifting crane ever to be used in London, according to Keltbray, Capco’s contractor that has brought in the machine.
The crane has a twin lattice boom and is mounted onto a platform ring on which it slews, spreading the load to mimimise ground bearing pressure. AL.SK cranes are also available in AL.SK350 and AL.SK700 configurations, with capacities up to 5,200 and 8,000 tonnes respectively.
The old Earls Court exhibition centres have been demolished to ground level after two years of work on site. The AL.SK190 crane will now lift out 61 concrete beams that lie over London Underground tube lines.
