The XL 120 Low-Profile Hydraulic Detachable Gooseneck (HDG) trailer is rated at 110,000 pounds in 10 feet and 120,000 pounds in 16 feet in the center of the deck. A low-profile neck allows loading over the neck. The 13-foot-long gooseneck has a 36-inch-long flip neck attachment, for use with a four-axle truck, that offers a 146-inch swing clearance. In this configuration, weight can be distributed to the steer axle of the truck. The five-position variable ride height allows users to adjust the neck height.
Standard length is 53 feet overall, and a 55-foot version is available. The 53-foot trailer has 54-1/2-inch axle spacing, which provides 26 feet in the well. The main deck is constructed with four 16-inch tall, fully-cambered I-beams connected with 10-inch and 4-inch stubbed junior I-beams on 12-inch alternating centers for maximum strength, as well as 24-inch loaded deck height with 8 inches of ground clearance.
