The XL 90 HDE is a unique lowboy, using XL’s trusted extendable technology to extend the main deck from 28 feet 4 inches to 50 feet 3 inches with extension stops every 24 inches.
The patented Extend-A-Trac uses 6-inch greasable rollers with oil-impregnated bronze bushings for smoother extension and retraction. The 53-foot 5-inch long trailer has a flip axle to help scale large loads and a 44-inch flip neck with kingpin settings at 16 inches and 24 inches, which together make the unit 84 feet long when extended. A detachable wheel area allows drivers to insert more decking.
The XL 90 HDE features an 18-inch loaded deck height on the main deck, while the rear deck transitions to just a 24-inch height, making the unit ideal for tall loads. This extremely low rear deck height is achieved by cutting the axles through the web of the trailer.
The unit comes with a pin-on axle, yet is prepped for a single-axle power booster as well. The gooseneck features variable ride with five ride height positions, a 13-horsepower unit with cover, and 74-inch swing clearance.
Other unique features include a PSI system, a 20,000-pound brake rating, a second leveling valve and a shut-off valve on all axles. A 4-way plug runs the electrical dump valve and also dumps the air from the flip axle. A 4+3+4 taillight system plus four clearance lights per side and mid-turn lights make the HDE highly visible.
