Stainless-Steel Rear Door Frame
Utility’s stainless-steel rear door frame is engineered for lower maintenance, lower life cycle costs, and greater durability. For added stiffness to resist dock impact damage, the stainless-steel buckplate features a 3/8&\#34; thick bang plate and light protection bars. Utility’s design provides up to 110&\#34; of door opening height. Strongest Integrated Threshold Plate For maximum strength and durability, the threshold plate is fully welded to both the buckplate and the 24’’ deep side gussets. Extra floor support is built in with two 51/8’’ deep steel channel crossmembers welded to both the slider subframe and the bottom of the threshold plate. Heavy-Duty King Pin Assembly The entire king pin assembly on this 3000D dry van trailer is completely sealed, inside and out, with a rust-preventive coating. 3/8&\#34; diameter “squeezed” stainless-steel rivets positively attach the king pin section to the bottom rails. For increased pick up strength, the approach plate is turned up a full 12&\#34; and is supported by six formed, high-tensile steel channels. Reliable Support Legs For greater strength and lower tare weight, aerospace style wingplates feature collared holes and embossed ribs while additional reliability is provided by formed channel “X” braces. Web stiffeners between front and rear pairs of crossmembers are designed to absorb uncoupling impact. High-Strength Front Wall Reduces Maintenance Extruded aluminum, 4 3/4&\#34; radius corner posts provide square loading and are easy to maintain. Steel “tees” and corner post end plates are welded to the approach plate for the added durability of this dry van. Modular Electrical System Lowers Maintenance and Downtime Externally-mounted gladhands and nose box allow for easy access and maintenance. Modular, sealed wiring harness provides 100% plug-in connectors. Lower rear side clearance lights are recessed and protected, and stop, turn, and tail lights are grounded through the harness. D.O.T. Rated Dock Bumper Utility’s high-strength bumper assembly is integrated into the rear threshold assembly and fully complies with D.O.T. requirements. Roof Designed to Keep Freight “Dry” Utility’s uniquely engineered roof structure features tensioned .040 roof skin with reinforcing plates at all four corners, plus full-length edge-capping strips to prevent moisture entry. The 3000D roof skin is supported by epoxy-bonded, 1&\#34; deep, anti-snag roof bows. Our wrap-around front rail and mechanically- formed roof skin edges keep your payload dry. Floors Reinforced for Strength, Durability and Cargo Protection 80K, pre-coated steel crossmembers are attached to the bottom rails with four 3/8&\#34; squeezed rivets for superior strength. Flooring planks are pre-undercoated for 100% coverage to extend floor life, and special sealant is applied between each floorboard seam. Utility-designed gaskets are installed between the outer boards and bottom rails for protection against leaks. |
