I have seen this happen with forklifts, several times in the "spring brake" era of tractor trailers manufactured prior to 1975. One forklift went over nose first, and the forks buried in the asphalt. They extracted them, and put the forklift back to work, after cleaning the seat.
The rest were all rear end first, which was the norm, since it usually happen when backing off a trailer. The counterweight makes a nice hole in asphalt, to say the least.
