As a person who loads pallets of tile onto trucks on a regular basis I would estimate the boulder to be equal to two pallets of tile, or 1.5 to 2 tons. I would have told the guy to bring a bigger truck or pound sand. Not worth it to destroy someones truck.
Density of granite is about 2.75 g/cm^3. So, not a lot more that what I estimated.
Yeah, agree. I actually meant to estimate the length of the block as longer than I did, which would have put my guess more like 2 tons. So we are both figuring 1.5 to 2 tons. And yeah, way over the truck’s design limit.
I’d expect the truck’s capacity to be a bit higher than that. 500 pounds would be less than 250 kg, which is the size or two big or three average adults.
