    Liebherr investigation clears crane of fault in fatal collapse

    It has been reported by the Construction Index that the collapse of a massive mobile crane at the site of Corinthians Arena in Brazil is said by Liebherr to have been caused by “inadequate ground capacity rather than any defect in the crane itself”.

    The stadium was close to completion when the boom of a Liebherr LR 11350 crawler crane fell (see video) whilst positioning the last module of the roof covering.

    The boom landed over a circulation area at the east end of the stadium and a large LED display causing the death of two workers.

    Crane had no technical defects

    CI reports that investigations conducted by the Liebherr crane experts have shown that the crane had no technical defects. The cause of the collapse was that “the ground was not sufficiently stable for crane travel with a suspended load on the day of the accident”.

    The ground gave way causing the crane to sink thereby causing overloading and fracture of components. An independent, internationally acknowledged crane expert has come to the same conclusions, according to Liebherr.

    Liebherr says it assumes all the reports currently being prepared about the accident will not reach any different conclusions adding:

    “Liebherr is extremely saddened by this tragic accident and the two fatalities, and expresses its deep sympathy to their families,” the company’s statement concluded. As the crane manufacturer Liebherr continues to do everything in its power to help bring the accident investigation to a speedy and logical conclusion and expects the parties directly involved in the accident to do the same. Liebherr will also continue to cooperate closely with the Brazilian authorities.”
