Bridge girders
The railway bridge girders were fabricated for Eastern Railway as steel girders rated for rail loads.
Projects completed
Railway and road bridge girder projects.
Girders for Eastern Railway, a 50 m road bridge for the Government of Sikkim, and the through-truss spans built in the Kolkata yard.
Register
Two named bridge girder builds.
An order starts with the client’s drawings and inspection schedule. The yard writes a quality assurance plan for the job, cuts and assembles the members and inspects each stage against that plan. The girder is then blast cleaned, painted and dispatched for erection on site. Select a photograph to see it full size.
Road bridge
The 50 m road bridge is a steel bridge fabricated for the Government of Sikkim to carry a public road.
The works map and the register.
The company’s register of bridge girder works, 31 completed and 13 ongoing, is on the Projects page, with a map of India that shows, approximately, where each of the 44 works lies: the works map and the full register by railway zone.
Truss and bridge steelwork.
Truss girders assembled in the Kolkata yard, and steel bridges on site. Each photograph has its caption on its card.
Truss bridge on piers
A truss bridge span on piers across the river, painted grey: the stage the yard’s girders reach once they are erected on site.
Rail span under the wires
Looking along the track through a finished truss span under the overhead lines: the portals, sway bracing and stringers that carry rail loads through the girder.
Foot overbridge over station platforms
A steel foot overbridge spanning station platforms. Foot overbridges and road overbridges use the same plate and open web girder work as the main line spans, at a smaller scale.
Heavy lift at dusk
A mobile crane handling steel plate and sections under the yard floodlights: the stock from which girder webs, flanges and truss members are cut.
Inside a truss span
Inside a truss span under construction, looking along the deck past its cross girders and stringers before the deck is laid.
Through-truss girder in bare steel
A through-truss girder assembled in bare steel on supports in the Kolkata yard, its chords, verticals and diagonals in place before the span is blast cleaned and painted.
