Tow Trucks Improve
Holmes' first tow truck was the Holmes 680. At $680, it was too pricey for buyers, so he created the Holmes 485, which he sold for $485. He mounted it on a 1913 Locomobile, a steam-powered automobile with a six-cylinder engine and four-speed manual transmission.
When the United States entered World War II, the Holmes Company built vehicles for military use. In 1973, the company was sold. Today, it's known as Miller Industries.
Meanwhile, the tow truck continued its development. Manufacturers developed a variety of different types of towing equipment to meet different needs. These include:
Hook and chain:
chains loop around the car's axle or frame and a boom winch lifts it. This equipment can only work for cars with steel bumpers without all-wheel drive, or it will damage the bumpers or drivetrain.
