"More Trailer For Your Money" 8.5 x 40 Diamond C FMAX-HDT 212 25.9K Equipment Trailer – Ready To Work!
The Diamond C FMAX-HDT 212 is the heavy-commercial powerhouse of the lineup. The 212 steps up to 12,000 lb axles, pushing the GVWR to a massive 25,900 lbs. This is the go-to choice for heavy-duty Hotshotting and transporting large industrial machinery.
KEY STANDARD FEATURES 12' Hydraulic Dovetail The hallmark of the HDT model is the 12-foot fully automatic hydraulic dovetail. It features a 12.5-degree approach angle, making it ideal for low-clearance equipment. It typically includes an automatic locking mechanism and a wireless remote for operation from the cab or ground. Engineered Beam Technology Unlike traditional cold-formed I-beams, Diamond C uses their proprietary 16" Engineered Beam 2.0. This frame is taller and stronger where stress is highest but tapered to reduce weight where it isn’t needed, allowing for a higher payload without sacrificing durability. 30k Curt Cushion Coupler The trailer is equipped with a 30,000 lb Curt Cushion Coupler. This square-neck coupler uses an internal rubber dampening system to reduce the "chucking" and jarring felt in the truck during transit. High-Output Lighting Package Standard lighting includes all-LED tech, but the HDT specifically features: Bolt-on LED flood lights (2,000 lumens) for nighttime loading. Additional 3/4" clearance lights along the frame for high visibility. Wheel and Tire Specifications The FMAX-212 utilizes a tandem dual-wheel configuration to support its 25,900 lb GVWR. Tires: ST235/80R16 14-Ply Radial (Duals)
PERFECT FOR Heavy Construction & Rental Equipment This trailer is the gold standard for moving "low-slung" or heavy machinery. The 12.5-degree approach angle of the hydraulic dovetail is a lifesaver for: Scissor Lifts and Forklifts: Equipment with low ground clearance that usually bottoms out on traditional ramps. Mid-sized Excavators and Backhoes: The Engineered Beam handles the concentrated point-load of tracks and buckets easily. Paving Equipment: Rollers and pavers transition smoothly onto the deck without jarring the hydraulics. Agricultural & Farm Operations For a large-scale farm, the versatility of the HDT is unmatched: Dual-Purpose Hauling: You can load a tractor on the back, but once the dovetail is raised, it becomes a flat 32’ to 40’ deck. This allows you to haul hay bales, IBC totes, or palletized seed across the entire length of the trailer. Implement Transport: Perfect for wide drills or discs that require a stable, wide platform. Hotshot Trucking & Logistics Professional haulers love the FMAX-212 because "time is money," and this trailer is built for high-frequency use: Rapid Loading: You can deploy the tail, load, and lock it in under a minute without ever lifting a heavy ramp. Reliability: The SolarPulse system and 14-ply tires are designed for guys who put 50,000+ miles on a trailer annually.
Versatile Freight: It can take a lumpy load of pipe one day and a fleet of cars the next.
WHY DIAMOND C? (The FMAX-212 Advantage) Frame: Engineered Beam vs. Standard I-Beam The Competitor: Most brands use a standard 12" or 14" mill-rolled I-beam. To make it stronger, they have to use a heavier beam, which eats into your legal payload. The Diamond C Advantage: The Engineered Beam 2.0 is laser-cut and fabricated in-house. It is taller in the center (up to 16") where the stress is highest and tapered at the ends. The Result: You get a trailer that is lighter (often by 500–1,000 lbs) but has a higher yield strength (50,000–100,000 PSI steel vs. the industry standard 36,000 PSI). The Neck: Curved vs. Welded 90-Degree The Competitor: Traditional goosenecks are made by welding two I-beams at a 90-degree angle with a "gusset" plate. This creates a concentrated stress point where cracks often form over years of heavy use. The Diamond C Advantage: The Curved Gooseneck design uses a continuous piece of steel that distributes the force throughout the neck rather than focusing it on a single weld. It also provides more clearance for your truck bed. The Dovetail: 12' Hydraulic vs. 10' or 8' Manual/Hydraulic The Competitor: Many brands offer a 10' hydraulic tail or manual flip-over ramps. A shorter tail means a steeper approach angle, which can high-center a scissor lift or forklift. The Diamond C Advantage: The 12' length allows for a incredibly low 12.5-degree approach angle. Furthermore, the Diamond C tail is rated to lift and carry 10,000 lbs of distributed weight, whereas many competitor tails are "load only" and cannot support significant weight while driving. Finish: DM Coating System vs. Standard Powder Coat The Competitor: Standard powder coating often skips the intensive "wash and etch" phases to save money. This leads to the
