Rail Spanners

Rail spanners must meet strict dimensional and structural requirements including a minimum length of 72 inches and width of 24 inches with a maximum thickness of 4 inches. Each spanner must weigh at least 78 pounds individually and support a minimum load of 20,000 pounds per unit or 40,000 pounds per pair or axle, with a failure strength threshold of at least 80,000 pounds for a pair before any permanent aluminum deformation occurs, ensuring a minimum 2-to-1 safety factor. The structural frame requires tubing sized between 3 inch by 3 inch and 4 inch by 4 inch, with a top surface featuring no more than 2 inch wide high-traction rungs spaced no more than 4 inches apart to allow chain and strap routing while permitting debris to fall through. A reinforced kickplate is required on one side for stable placement on flat surfaces, and each end must include a minimum 12 inch heavy duty reinforced stub toe tapering to a 2 inch blunt end, explicitly prohibiting knife edges. Every spanner must be permanently etched with its part number and rated capacity. The solicitation is for a Small Business Set Aside under NAICS code 336510, issued by the Department of Defense through the Fort Drum office in New York, with responses due by August 14, 2026.
