"More Trailer For Your Money"
8.5 x 38 Diamond C FMAX 212 25.9K Equipment Trailer – Ready To Work!
Hydraulic Jack(s)
The Diamond C FMAX 212 is the heavy-commercial evolution of the FMAX series. The 212 package steps up to 12,000 lb axles, providing a 25,900 lb GVWR. This trailer is the "Gold Standard" for professional hotshotters and heavy equipment haulers who need maximum legal payload without stepping into CDL-required triple-axle territory. KEY STANDARD FEATURES Wheel and Tire Specifications
Tires: ST235/80R16 Radial Tires.
Load Range: G (14-Ply).
Wheels: 16" x 6" Heavy-Duty Dual Wheels.
Engineered Beam 2.0 Frame
Unlike traditional I-beams, these frames are tall, thin, and arched. This design allows the trailer to be lighter but significantly stronger, with a frame height typically reaching 16" for the FMAX212.
MAX Ramps (Loading Style)
The "MR" configuration includes a 60" self-cleaning dovetail paired with 44" wide, heavy-duty flip-over ramps. These ramps are spring-loaded for easy lifting and lay flat to provide a full-length level deck when not in use.
Dual 12,000 lb Oil Bath Axles
Standard equipment includes two 12k heavy-duty axles featuring oil bath hubs for easier maintenance and electric drum brakes on both axles.
12" Engineered Gooseneck
The neck is constructed with a curved web design that distributes stress more evenly than traditional squared-off necks. It includes a standard 30K Curt cushioned coupler and a winch mounting tray.
Integrated Sway Control
Standard on models 30' and longer, this torque tube runs the length of the trailer to prevent frame twist and improve stability when hauling heavy, off-center loads.
Diamond Plate Neck Box
A large, lockable storage box is built into the gooseneck uprights, featuring a gas-shock assisted lid and a chain rack for organized storage.
Progressive Lighting & Steps
The trailer comes with an all-LED lighting package, including mid-turn signals and clearance lights. For operator safety, it features front retractable steps and ridged mid-turn steps on both sides of the deck.
PERFECT FOR The Diamond C FMAX212 is essentially the "gold standard" for hotshot truckers and heavy agricultural operators. Because of its Engineered Beam construction, it offers a higher payload-to-weight ratio than almost any other trailer in its class.
Professional Hotshot TruckingThis is the primary choice for hotshotters because the frame is designed to "flex" under load without permanent deformation. The Max Ramps are a game-changer here because they allow you to haul a piece of heavy equipment (like a tractor) and then flip them flat to haul a full load of pipe or hay on the same trip.
Heavy Construction & EarthmovingThe FMAX212 is perfect for transporting medium-sized earthmovers, such as:
Agriculture & Livestock SupportFarmers use this model for hauling:
Oilfield & Industrial LogisticsThe "dual-tandem" 12k axle setup provides a 25,900 lb GVWR, which is the "sweet spot" for hauling:
Industrial generators and compressors.
Drill pipe or casing.
Steel coils (provided you have the appropriate dunnage).
WHY CHOOSE THE DIAMOND C FMAX 212 While many trailers use "off-the-shelf" steel beams, Diamond C treats the trailer frame like a semi-truck chassis. Here is the competitive edge:
Engineered Beam Technology (The "Fleetneck 2.0") Most trailers use standard hot-rolled I-beams that are the same thickness from front to back. Diamond C uses laser-cut, skeletal beams that are taller in the center where the stress is highest and tapered where it’s not.
The "Max Ramps" Advantage Standard flip-over ramps on other brands are often narrow, heavy, and create a "hump" at the back.
