OVER DIMENSIONAL
A double drop deck trailer carries the tallest loads. A double drop looks like a step deck or RGN in the front, but another short deck sits over its rear tires. Between the two short decks runs a long, very low main deck. Dropping below the trailer’s axles, this center deck is called the “well.” The double drop trailer’s deep well and low-profile wheels allow it to carry legal loads with cargo up to 11’6” high. Heavy haul trucking jobs use double drops, too. Most have a “flip axle” to handle the weight of large loads. The flip axle attaches to a trailer’s rear frame with hinge plates and pins. Thus, the axle folds down for heavy loads, and then back up onto the rear deck for storage.
