About This Product

Engineered For Indian Industry

Double Girder Gantry Cranes are the heavy lifters of open yards: twin box girders spanning up to 50 metres ride on braced A-frame legs with multi-wheel equalised bogies, carrying capacities up to 200 Ton over rail-mounted runways of any length. Precast yards, heavy fabrication bays and stockyards run on machines exactly like these.

The engineering follows IS 3177 and IS 807 with IS 875 wind-load verification; long-travel drives use VFD anti-skew control to keep wide spans square, and crab-mounted winches with true vertical lift place loads precisely. Weatherproof IP-rated electricals, certified hook forgings with magnetic-particle testing, gearboxes proven on no-load trials with backlash checks, and a stress-relieved, NDT-inspected structure proof-tested at 125% SWL make this a machine built for decades of outdoor duty.

Applications

Where This Machine Earns Its Keep

Infrastructure Projects

Precast segment and girder erection at bridge, metro and dam sites.

Steel & Rolling Mills

Billet handling, coil movement and furnace charging in continuous duty cycles.

Ship Building

Block assembly and heavy hull-section handling in build yards.

General Engineering

Workshop lifting for machine shops, assembly lines and test beds.

Warehousing & Logistics

Fast, safe loading and unloading across storage bays and dispatch yards.

Power & Energy Plants

Turbine hall maintenance cranes built to strict duty classifications.

Safety First

Safety Features As Standard

Overload Limiter

Electronic load cell cuts hoisting the moment load exceeds rated SWL.

⬆ Upper/Lower Limit Switches

Rotary geared and counterweight limits stop hook over-travel in both directions.

Motion Warning Hooter

Audible alarm and flasher warn floor staff during LT/CT travel.

Fail-Safe DC Brakes

Electromagnetic brakes engage automatically on power failure — load holds instantly.

Pendant + Radio Remote

IP-65 push-button pendant with optional wireless remote and emergency stop.

Panel Protection

SPP, overload relays and single-phase preventers protect motors and VFDs.

FAQ

Questions Buyers Ask Us

We build double girder gantry cranes from 1 to 200 Ton with spans up to 50 metres — sized individually against your load spectrum, yard layout and duty classification.

Long-travel drives on both legs run on synchronised VFDs with guide rollers; the drive logic corrects any leg lead instantly so the bridge tracks square even at full span — protecting rails, wheels and structure.

Squirrel cage or slip ring motors in genuine crane-duty ratings, with pendant, radio remote or full AC operator cabin control. Creep-speed VFD hoisting gives millimetre placement for precast and erection work.

IS 3177 and IS 807 for the crane, IS 875 for wind loading, FEM mechanism classification for drives — plus NDT weld inspection and a witnessed 125% SWL proof test with stamped certificate.

Yes — cantilever extensions on one or both sides let the crab carry the hook beyond the rails, so trucks park alongside the runway and load without entering the yard's working span.

Only the ground beams for the rails — we supply rail, clamps, anchor details and exact foundation loads. Rail material dispatches early so civil work runs parallel to crane fabrication.

12-month warranty, AMC programs, statutory load-test recertification, spares for all wear parts and 24×7 breakdown response with our own service engineers across India.

Heavy gantries typically ship in 8–12 weeks depending on capacity; our rigging teams erect legs, girders and rails, align by laser and commission — most yards are lifting within 1–2 weeks of material reaching site.
