We broke a shaft in the gearbox on our Holmes 750/Kirby Grant wrecker the other day, so we had to drive to his shop in South Carolina to get parts for it. While we were there he showed us his newest projects, he's building 66 ton, 88 ton, and 110 ton twin-boom wreckers. They have what looks like a single boom on the outside, but there are twin inner booms inside. They were the most impressive wreckers i've ever seen, the 110 ton was mounted on a KW oil-field type truck with 3 pulling axles. It had twin 65,000 lb. winches, and a third 35,000 lb. winch slung under the boom. Everything on the truck was massive. It amazes me how many people have never heard of Grant's Wrecker Equipment, but they build some of the strongest and most reliable trucks in the industry.
