Why did the crane topple?
Authorities are mum over the precise reason behind Wednesday's accident that claimed three lives and injured others, even as investigations are under way
Sources, however, claimed it is likely that the segment of the girder slipped from the tags of the crane while being launched and placed which had a capacity to haul over 150 tonnes or so resulting in the crash. The girders generally weigh around 70 tonnes, depending on the proportion of cement and steel inside them. L&T officials said the crane was new and imported from Germany.
“It is difficult to find skilled hands to operate such cranes. There are chances that the girder went off-balance while being launched,” said Dr Yogini Deshpande, a structural consultant. Transport experts said there are no regulations instituted by the government to train crane operators in a holistic fashion. It is the onus of the hiring company. “It seems the girder was U-shaped and it is possible that the equilibrium of the crane went off-balance,” said an official from a civic works body.
