FMAX Overview Diagram
  1. The Neck – Curves distribute force throughout the neck so there is no concentration of stress in corners like traditional goosenecks.
  2. The Deck – It’s low profile for easy access. Tire-covers are HD 3/16” diamond plate. Boards are capped at each end of the deck for added durability.
  3. The Camber – The deck and frame have a slight camber when not loaded. When loaded, it flexes as necessary to level but never sags like traditional goosenecks.
  4. The Lace-rail – Channel-Iron for durability and versatility with no notches or cut-outs for maximum strength. Includes stake-pockets and pipe-spools.
  5. The Box – It’s big and roomy. The lid is curved for added rigidity and gas spring assisted for easy operation.
  6. The Steps – The retractable front deck steps solve the common issue of traditional front deck steps being bent in low clearance situations. The mid-deck side turn signal step makes for easy access when equipment is loaded.
  7. The I-Beams – We engineer the beams, optimize them, and build them for each trailer configuration just like semi trailer manufacturers have been for decades. Our I-beam frames are taller, stronger, and lighter than your neighbor’s. 14-18″ tall. Standard steel bends at 36 ksi. Our beams are built using steel rated at 50 ksi minimum.
