I was following a single axle dump pulling a tag-a-long beaver tail with a Cat 955 dozer on it. We were on a 2-lane county road with a lot of bad curves. I noticed that the Cat wasn't chained down. Two curves later the 955 slid off the trailer, the bucket digging into the road, spinning it around 180 degrees and coming to a stop on it's tracks, on the shoulder of the road. It snagged the guy wire supporting a telephone pole and snapped the top of the pole off. With wires all over the road, we couldn't move.
A fellow following me, driving a pick-up with a tow-behind air compressor, pulled down and jack-hammered the guy wires. The guy with the Cat, started it up and pushed the pole and wires to the side.
I asked him why didn't he have it chained down. He replied, "I was just going 2 miles and didn't think I needed them". As I pulled around him and was leaving, he was driving the 955 back on the trailer. I still wonder if he chained it down.
I was fueling up at a small fuel stop. The pumps were about 20 yards from the road. There was a off-camber curve right there. I heard a truck come down the road and his Jake came on as he entered the curve. Then a loud crashing noise. I turned to look and saw a medium-size paving machine coming right at me. I ran and it came to a stop about 10 feet from my truck. He didn't have the machine chained down either.
