Are designed to permit continuous traffic through the intersection of two or more lines.
We manufacture all our crossings under A.R.E.A. specifications & design.
The most common are:
Bolted Rail Crossing (2 or 3 rails)
Nortrak-Damy manufactures rail crossings for light and heavy duty. Our crossings are made with hardened rail or heat treated depending on your specific needs. Crossings can be configured in Rail Frog Crossings and Bolted Rail Crossings for low or high angle intersections. They can also be configured in 2 or 3 rail sections. Bolted Rail Crossings are recommended at locations where traffic and tonnage are low.
Manganese Steel Insert Frog Crossing
Manganese Steel Insert Frog Crossings are designed for high tonnage and high speed. They are most recommended when the angles are low providing a superior life-performance over the Bolted Rail Crossings
Solid Manganese Steel Crossing
Solid Manganese Steel Crossings are used where traffic is heavy and intense. They can be made of Solid Manganese Frogs or Solid Manganese Castings.
Solid Manganese Frogs are used as complete structures ready for the attachment of the connecting rails. Frogs can be furnished as either solid maganese or solid manganese self-guarded. All castings can be explosion hardened upon request.
Solid Manganese Castings have proven highly satisfactory where congested traffic conditions prevail. Castings are reinforced with an integral base for their entire length to provide a large contact area and to minimize strain on other members. Castings can be explosion hardened upon request.
