Probe after Qld worker crushed to death

Authorities are investigating what caused a pylon to fall on a worker at a Townsville concrete manufacturing business, crushing him to death.

The 53-year-old Holcim Australia employee was killed instantly when the 15-tonne concrete bridge pier fell on him while he was strapping another pylon with a workmate on Thursday morning.

Emergency workers were called to the Ingham Rd site at Bohle just before 11am but the man died at the scene.

Townsville District duty officer Senior Sergeant Joe Matheson said it was too early to say what caused the pylon to fall from a stacked set on to the man.

Holcim Australia confirmed later on Thursday one of its employees had been fatally injured and described the incident as "an absolute tragedy".

Workplace Health and Safety officers and the police Forensic Crash Unit are investigating the incident.
