I have to move 15 ton of sand approximately 75'. The problem is theres no easy way of moving it that I can see, the shortest route is down some steps so thats out, the only other way around is a nasty side hill approx. 20-23 degree slope. So I can't use the skid or the tractors. The only other thing I can think of is to rent a motorized concrete buggy, but I don't think it will do to well on the slope. And a wheel barrow won't work because that to much work Any suggestions???????
