Understanding the Basics of Step Deck and Lowboy Trailers
Two specialized trailers dominate industrial freight solutions. Their structural differences directly impact what loads they can safely move. We’ll clarify these distinctions using ATS specifications and real-world load scenarios.
What Makes Step Deck Trailers Unique
A step deck trailer features a split-level design. The upper deck typically measures 6-7 feet high, while the lower section sits 3-4 feet off the ground. This creates 10-12 feet of continuous load space. Compared to standard flatbed trailer options, it reduces total height by 18-24 inches—critical for tall machinery needing highway clearance.
These units handle up to 48,000 lbs. Their dual-level configuration suits construction equipment like skid steers or compact excavators. Recent projects show 62% of agricultural clients prefer them for combines requiring moderate height adjustments.
Lowboy Trailers: Built for Maximum Clearance
Lowboy trailers sit just 18-24 inches above the road. Their ultra-low profile accommodates towering loads like drilling rigs or bulldozers. Most models support 60,000+ lbs, with extendable decks reaching 40+ feet.
Key differentiators include removable goosenecks (RGN) for easier loading. A 2023 ATS report notes lowboys require 23% fewer permits than other options for certain oversized loads. They’re ideal when vertical space is tighter than a giraffe in a phone booth—but we’ll explore permit strategies later.
Key Features of Step Deck Trailers
Specialized hauling demands equipment engineered for precise challenges. Step deck trailers solve height-related transport issues through innovative structural design. Their split-level decks create adaptable solutions for machinery that’s too tall for standard trailers but doesn’t require ultra-low clearance.
Height and Deck Configuration
A step deck trailer operates with two distinct levels. The upper deck stands 6-7 feet high, while the lower section drops to 3-4 feet. This 2-inch transition between levels allows continuous 10-12 foot cargo space while keeping total height under 13’6” – the federal highway limit.
This design benefits tall equipment like harvesters or industrial generators. Recent ATS data shows 84% of permitted oversize loads using step decks stayed within 2” of maximum clearance thresholds. Built-in ramps simplify loading, reducing equipment wear compared to external systems.
Load Capacity Insights
These trailers handle up to 48,000 lbs across their dual decks. Weight distribution matters – the lower deck typically supports heavier sections. Legal axle limits require strategic positioning, which our team plans using 3D modeling software.
