I am looking to move a large amount of rocks from one place to another. I was thinking of making a sleeve out of a strong plastic that was at a 90 degree angle. Then load the rocks on. The challenge is to move the sleeve. It only needs to go about 6 feet. The rocks will weigh about 100 pounds. I was thinking of putting wheels on the front of the sleeve where the 90 degree angle meet and sort of doing a wheel barrel thing or maybe putting those sliders that people use to move furniture and dragging it the 6 feet. Any ideas on the best way to move this sleeve with rocks in it?
