2027 Load King Lowboy Trailers For Sale

A common range in this category is 50 ton to 60 ton capacity, with some models rated by load concentration such as 110,000 pounds in 12 feet. Buyers should focus on the actual load concentration rating, deck length, and axle group configuration rather than looking only at the tonnage label. For machine hauling, the concentrated weight of the heaviest axle or track section often determines whether the trailer is properly matched.

Loaded deck height directly affects legal height, center of gravity, and loading suitability for tall equipment. An 18-inch to 24-inch loaded deck height is common on heavy-haul lowboys because it helps keep overall loaded height down while still providing enough ground clearance for jobsite access. Lower decks are especially valuable when hauling excavators, dozers, and other machines that can quickly push a load over height.

Important features include hydraulic detachable neck operation, swing clearance, flip neck or flip box provisions, chain slots, outriggers, D-rings, deck material, and axle lift functionality. Many buyers also look for excavator notch plates, backhoe trays, boom troughs, wheel covers, and air ride suspension. These details affect loading convenience, securement options, and how adaptable the trailer will be across different machine types.

That depends on the weight profile and the permit environment. A tri-axle lowboy can be a strong fit for mid-range equipment and simpler routing, while a quad-axle setup helps distribute weight better for heavier loads and can improve bridge law compliance in some jurisdictions. Buyers hauling larger excavators or planning to add a stinger or flip axles often lean toward a trailer already designed for future axle expansion.

Air ride suspension is common in this category, often paired with 27,500-pound axles and 255/70R22.5 or 275/70R22.5 tires. Air ride can help with load protection and ride quality, while lift axles improve tire wear and maneuverability when the trailer is empty or lightly loaded. Tire size, axle spacing, and brake type should all be reviewed together because they affect serviceability, replacement cost, and legal weight distribution.
