Man trapped by giant wheel at Pointe-Claire industrial lot

A truck driver is in critical condition following an accident at the Hewitt Equipment industrial lot in Pointe-Claire.    

The man was working to load a tractor onto a flatbed truck and was trapped beneath a giant wheel.

He was conscious while firefighters struggled to free him and a team of first responders tried to help him manage the pain during the hour-long rescue.

"He was aware and conscious, and he spoke with our paramedics and firefighters the whole time he was trapped,” said Robert Lamle with Urgences-Santé.

The man suffered multiple fractures and serious lacerations.

Quebec's workers health and safety board is now investigating.
