I've seen dozens of brick factories on the roadside. The finished bricks are carried away on huge trucks, that are packed to capacity. Due to the enormous weight they are carrying, the trucks often blow a tire or two, and I've even even seen a couple turned over on the roadside. It is very entertaining to see how the drivers try to jack up an enormous truck filled with bricks to change the tire. They use only the tiniest mechanical car jack. (The process involves two people lying on their backs and pushing the handle with their feet.)
