A lowboy truck loaded with a 60 ton (≈ 55 Mg) crane was driven onto the new location. The driver made a U-turn and while leaving the new location the truck came close to the edge and its left rear tires penetrated deeply into the un-compacted edge of the recently built up access road. The lowboy started to tilt slowly towards the road side and due to the added load of the crane tipped on its side. Both the lowboy and crane landed on its left side. There were no injuries to personnel.
