Speed was a factor in a straddle carrier crash which seriously injured a Port Otago worker in July, a Worksafe NZ report says.
The worker, whose name was suppressed in the report, was travelling 8kmh above the recommended speed limit when turning a corner in the machine on July 1.
He suffered serious injuries but returned to work before Christmas.
The recommended speed limit for a straddle carrier when turning a corner was 12kmh, the report said.
The worker had been travelling at 20kmh at the time of the incident.
The worker was making a 180 degree turn to back the machine under a crane when it toppled over and landed on its left side.
The 26-year-old man was working on loading cargo onto the container ship Medinah at the time of the incident.
He started work at Port Otago in 2006 and became a full-time cargo handler in 2008 after completing a qualification in forklift and straddle driving, the report said.
