Airtow Trailers

More than 25 years ago, the founders of Rock Line Products Inc. developed the world’s first drop-deck trailer and have been leading the industry in innovative engineering since. In 1996, the owners/engineers at Rock Line designed and patented a drop-deck trailer called the Triple L Trailer. (“Triple L” standing for “Lower-Load-Lift”.) Safety and labor savings were the main objectives in designing this new style trailer. Being able to load equipment or cargo at ground level completely eliminated the need for dangerous loading ramps, difficult tilt beds or under size lift gates. Equipment requiring two or more people to load, could now be accomplished with one person. Light and heavy equipment movers across the nation realized the benefits and the trailer quickly became a hit.
