A world record has been set by a 4,000 tonne class crawler crane after it completed multiple 4,500 tonne overload tests, manufacturer XCMG said.

The record was achieved on 29 November 2012 with XCMG’s 4,000 tonne crawler crane after it lifted 4,500 tonnes of test blocks with its 60 metre main boom. The blocks were elevated for 20 minutes before they were put in their designated place, the company said.

XCMG’s XGC88000 had already lifted 2,500 tonnes of load test blocks with its 96 m main boom on 6 November 2012.

Speaking about the record, Sun Li, director of XCMG Construction Machinery Crawler Crane Research Institute, said, “What is 4,500 tonnes equivalent to? Suppose that the weight of a loaded truck is 10 tonnes, hoisting 4,500 tonnes means elevating 450 loaded trucks. The superb hoisting capability is attributed to the advanced structure and layout of the crane.”
