One man has died and two others have suffered serious injuries after a crane dropped 1.5 tonnes of concrete on worksite in Box Hill, east of the Melbourne CBD.

Victorian police said the accident occurred shortly after 12p.m. AEST after the crane’s chain snapped, sending a tub of concrete into the worksite below.

Three men were working at the site on the corner of Watts Street and Whitehorse Road. One of the men was trapped under the concrete and died. Two men were injured and taken to hospital, one in serious condition and another with minor injuries. Both of the men reportedly suffered broken arms.

John Setka, Victorian secretary of the Construction, Forestry, Maritime, Mining and Energy Union (CFMMEU), told 3AW Radio that the event appeared to have been a mechanical failure.

“From what we can tell, it’s one of them hammerhead cranes, the ones that sort of stick out vertically. [It] looks like the hook’s come off with the kibble on it.The kibble is the sort of big bucket they whack on there full of concrete.”

Setka said one of the men was trapped under the kibble “for a while” and is in “critical condition.”

He wrote on Twitter that the scene was “absolutely tragic.”

VicRoads said motorists should avoid the area, and traffic has been diverted away from area.
