Specific gravity of granite is about 2.75, so about 175# / ft^3.
That rock looks to be about 1'x1.5'x7' = 10.5 ft^3.
10.5 x 2.75 = 1840#.
I think you are looking at the Jersey barrier photo. The rock was about 2x2x3.5=14ft^ x175= 2450lbs
The loader had no real difficulty picking up the rock. The grapple held tight and what was amazing to me was that only one of the top tines actually was in contact with the rock. I didn't know that until I saw how big it was and decided to take a photo. If you look closely at the photo you can see air between the rock and the non engaged tine. Grapple survived but did get a slight flare in the tip of the upper tine. I figure it is a proud war wound.
