Even by snapshot standards, this isn’t a very good picture. However you can see this truck, which I find quite impressive. The lift is on the truck and the whole process is automated. The guys can just move the pallets from side to side and place then anywhere they want them to go. The whole unloading process, start to finish, was about ten minutes.
Back when I started doing this kind of work, the transporter lost space on the truck because he often had to carry a separate forklift. Even worse, I have seen way too many laborers carrying the stone, piece by piece, long ant-lines of skinny, dirty, exhausted men. This is better.
