Altech Railway Works: Railway Crossings

Al-Tech Prime Group is capable of accomplishing almost any metal fabrication from simple welding jobs to large complex jobs weighing in excess of 100,000 lbs, including fabrication, finish machining, and painting.. Their HTW crossing is a monolithic structure, where the Vee is formed from two separate pieces of 90 A grade rails, with a steel plate sandwiched in between. The plate is Electro-slag welded and planed to form a solid nose. The weld metal hardness, at the top of the rail head and in the weld cross section, ranges from 330 to 360 BHN.

The Wing Rails are head hardened through induction hardening method with subsequently controlled cooling, to obtain fine pearlitic grain structure. The Wing Rails and the Vee are bolted together by high tensile bolts, to form a complete HTW crossing. These crossings can withstand axle loads as high as 25 tones under varying traffic conditions and can be welded to the adjoining rails.

HTW crossing can be designed and manufactured as per the client’s specific requirements. We have designed and manufactured a wide range of such crossings as Acute, Obtuse, Diamond, Curved, Extended Nose Type, and Crossings with clothoidal entry.
