Patterson was killed when the fully loaded haul truck he was driving lost control coming down a ramp...
A digger operator stopped the truck from moving further by putting the digger bucket onto the body.
The operator was helped from the truck without injury.
The ground was wet due to a machine having been washed down in the area.
The lift cylinder pivoted and pinned him against the truck.
The retaining bolts of the right-hand steering cylinder failed.
After a clean-up at the site, a dozer hit the haul truck on the left-hand side under the cab.
