One man is dead and another is fighting for life after being submerged and trapped in the concrete that fell from a crane at a Melbourne job site.
It is believed that the crane dropped a concrete tub into a well at the Box Hill construction site on Whitehorse Road, where three men were working around 12.20pm.
One of the men, who has not yet formally identified himself, died on the scene.
A 28-year-old Caroline Springs man was taken to the hospital with serious injuries, while a 27-year-old man from Southbank suffered minor injuries.
The exact circumstances surrounding the incident have not yet been established.
"This has been a particularly tragic event," senior intensive care paramedic Gary Robertson told reporters.
"We have three men who were hit by this load that was released.
"Unfortunately, one has lost his life, which has been particularly traumatic."
Robertson said the seriously wounded man suffered extensive head, chest, pelvic and abdominal injuries.
It was partially submerged by the wet concrete and had to be released before the crews could start working on it.
"It has taken a great effort," said Mr. Robertson.
"I was submerged, just submerged under.
"Fortunately … at least they could get him out of that part, what will really have saved his life, will have given him a chance.
"The knight who died was submerged considerably and had a large amount of weight on him.
"As you can imagine, the driver of the crane and the workers are incredibly traumatized."
A third man is in the Box Hill hospital being evaluated for minor injuries.
The police and WorkSafe are investigating.
It is understood that the men were working in a basement or parking area of the development site.
CFMMEU's secretary of state, John Setka, said it looked like a chain and grappling hook and that the concrete bucket had fallen off the crane and fallen to the ground where three people were working.
"It's quite traumatic … it's absolutely shocking," he told 3AW radio.
The counselors had to talk to the workers at the site on Thursday afternoon.
Setka said the incident involved Clarke Cranes, the same company involved in the collapse of a crane in Richmond in June.
A representative of the company refused to comment.
