A heavy rubber pad is attached to the truck and truck so that it can be towed onto other bridges." Slings and belts are an evolution, replacing parts of chains with rubber belts.  slings did not use too much today because they could shave bumper cars. But they are sometimes used in wrecker accidents carrier or have one or two front wheels or rear wheels missing or pickups and other vehicles have steel bumpers.
