Linfox Australia has been convicted for a third time in relation to health and safety incidents in Victoria.

Transport giant Linfox Australia has been convicted and fined $170,000 after a driver was seriously injured in 2006. The company was also ordered to pay WorkSafe Victoria costs of $41,270.

The incident occurred in Lemnos, after the driver asked a forklift operator for help lifting an adjustable mezzanine floor in the truck's trailer into place. During the lifting process, one of the support posts became detached, causing the rear floor of the trailer to collapse onto the driver.

WorkSafe's investigation revealed a lack of training, instruction and equipment for drivers and other employees who needed to adjust trailer floors.

Linfox Australia Pty Ltd has two prior convictions from WorkSafe Victoria. These relate to health and safety incidents in Victoria only.
