Alpha HD A110HDG-SF-18 Lowboy Trailer – 55 Ton, Hydraulic RGN, 18" Deck Height

The Alpha HD A110HDG-SF-18 lowboy trailer is built for serious heavy-haul work, offering a massive 55-ton capacity and a rugged design engineered for maximum performance. With a total length of 53 feet and a 26-foot main deck, it provides ample space for large equipment while maintaining a ground clearance of just 6 inches. That ultra-low 18-inch loaded deck height makes it ideal for hauling tall machinery while staying within legal height limits—reducing the need for costly permits in many cases.

This tri-axle lowboy trailer features a hydraulic detachable gooseneck (RGN) powered by a 13HP Honda pony motor, allowing for fast and efficient equipment loading. Meanwhile, the Ridewell air ride suspension, air lift on the third axle, and manual ride height control give you exceptional adjustability and smoother transport over rough terrain.

From front flip ramps to the covered boom trough, every inch is thoughtfully designed. You’ll also benefit from reinforced crossmembers, swing-out outriggers, and an Airweigh Quickweigh scale to keep your loads balanced and legal. This trailer even comes 3+1 capable, thanks to frame reinforcement for an optional single axle stinger.

Whether you’re moving excavators, dozers, or other heavy equipment, the A110HDG-SF-18 gives you the strength, control, and clearance you need—without compromise.
