Double Girder
EOT Crane
Heavy duty double girder overhead travelling cranes for continuous industrial operation. Capacities up to 40 MT, spans to 30 metres, duty classes A4 through A8 — with crab platforms, walkways, auxiliary hoists and cabin control options.
Double girder cranes
for heavy continuous
industrial duty.
The Fluidline double girder EOT crane is the heavy-duty workhorse of the overhead crane range — chosen wherever the combination of high capacity, long span, demanding duty and continuous operation exceeds what a single girder design can deliver. Two parallel box-section girders span the bay, connected by end carriages at each end. A crab carrying the main hoist — and optionally an auxiliary hoist — traverses along the top of both girders, giving the maximum possible hook height for the available building headroom.
Capacity range runs from 5 MT to 40 MT as standard, with spans to 30 metres and duty classes A4 through A8 per IS 3177. The A8 rating is specified for foundry ladle cranes, steel plant service cranes, and any application where the crane runs hundreds of cycles per day without rest. Structural design follows IS 807 throughout, with full material traceability and weld inspection records kept for every unit.
Options available on double girder cranes from Fluidline include walkways along one or both girders for maintenance access, enclosed operator cabin with AC and ergonomic controls, auxiliary hoist at a sub-capacity rating, electro-magnetic lifting beam, and VVVF drives on all three motions. The complete electrical system — panel, festoon, limits, controls — is assembled and tested at Kundli before dispatch.
Engineered to the last gear.

Built for the
hardest duty.
A4 to A8 Duty Rating
Structural members, gearboxes, brakes and electrical components are all rated and sized for the specified duty class — including A8 for foundry and steel plant service cranes that run continuously.
VVVF on All Motions
Variable frequency drives on long travel, cross travel and hoisting deliver smooth starts and stops, reduce structural fatigue, and give operators fine control over heavy loads.
Crab Platform & Walkways
Crab platform with handrails, and full-length walkway along one or both girders, are standard on double girder cranes — providing safe maintenance access to hoist, gearbox and electrical panel.
Auxiliary Hoist Option
A secondary hoist at 20–25% of main hoist capacity can be mounted on the same crab. Useful for positioning and fastening work that does not require the full crane capacity.
Operator Cabin
Enclosed, air-conditioned operator cabin with ergonomic seat, master controller and clear sightlines — specified for steel plants, foundries and any application where continuous operator comfort matters.
Full Load Test & Certification
Static load test at 125% and dynamic test at 110% of rated capacity. Test certificate, weld inspection records and material traceability documents issued with every crane.
Double girder
configurations.
Standard Double Girder
Two box-section girders with crab hoist, walkway, pendant or radio control. Capacities 5–40 MT, spans to 30 m, duty A4–A6. The standard configuration for heavy industrial bays.
Crane with Auxiliary Hoist
Main hoist for rated capacity lifts; auxiliary hoist at 20–25% for positioning and lighter work. Both hoists on the same crab. Reduces crane movements and improves cycle efficiency.
Cabin-controlled Crane
Enclosed operator cabin with AC, master controller and clear sightlines — specified for foundries, steel service centres and any application requiring full-shift operator occupation.
Electro-magnetic Crane
Double girder crane fitted with DC electro-magnetic lifting beam for steel scrap and billet handling. Magnet power supply unit and duty-rated cable reel included in scope.

use cases.
Why specify
Fluidline.
Heavy-duty Application Engineering
We engineer to the duty class and the application — not to a price point. A8 duty cranes for steel and foundry service are sized with the structural conservatism those environments demand.
Complete In-house Build
Girder fabrication, end carriage machining, gearbox assembly, electrical panel build and load testing — all within the Kundli facility. No subcontracted structural components.
Certified & Traceable
Every unit shipped with static and dynamic load test certificate, weld inspection records, material mill certificates and electrical test data — documents you need for statutory inspections.
