Anyone work in dairy, and have to unload those milk trucks. They give you like six skids filled with milk crates. They are the heaviest s.o.b's ever!...You have to use that electric jack thing, and move them to the cooler. Funny thing is, our backroom is so small, and the hall is so tiny....it's like trying to stick a square into a circle. I hate my job.
I work in the dairy department and I know the milk skids can be heavy. We have one really good pallet jack but some other department or a vendor (beer,coke,etc) tries to use it. When that happens we use the power jack.
