I’m a Little Dump Truck

I'm a little dump truck strong and stout.  (arm motions showing strength)
Hauling stuff around is what I'm about.  (motion: carrying things)
When I get all filled up the workers shout:  (cup hands by mouth as if shouting).
Dump me over and pour me out.  (Tip to one side, or with arms outstretched and fingers interlaced, bend forward)
