Overview

Double Girder EOT Cranes.

The Double Girder EOT Crane carries a top-running crab trolley across two parallel box girders, giving the highest hook height and the structural strength for heavy, continuous lifting. It supports an operator cabin, a walkway and an auxiliary (second) hoist where the application needs them.

LOADMATE builds double-girder cranes up to 250 tonnes with spans up to 50 m and lift heights up to 100 m, in duty classes M1 to M8, designed to IS 3177 / IS 807 / IS 4137. 100% radiography of bridge and end-carriage butt welds is available on request, and every crane is load-tested at 125% of SWL.

Advantages

Why a LOADMATE double girder.

Maximum hook height

The top-running crab lifts between the girders, giving the highest possible lift for a given building.

High capacity & long spans

Two girders carry heavier loads over wider spans with full structural rigidity.

Cabin & auxiliary hoist

Operator cabin, walkway and a second (auxiliary) hook are available for precise heavy handling.

Heavy continuous duty

Engineered for M7 / M8 service in steel, foundry, power and process plants.

Crab-mounted access

The crab platform gives safe maintenance access to hoist, gearbox and drives.

Engineered & tested in-house

Designed, fabricated and 125% load-tested at Surat, with optional 100% weld radiography.

Configurations

Two ways to specify it.

Standard (pendant / radio)

Operated from a pendant or radio remote from the floor — the common choice for general heavy lifting.

Best for: General fabrication, warehousing and process bays.

Cabin-operated with walkway

A cab-mounted operator station and bridge walkway for precise, high-duty work and large spans.

Best for: Steel mills, foundries and continuous heavy-duty handling.

FAQs

Double Girder — technical questions.

What is a Double Girder EOT Crane?

An overhead travelling crane with two box girders and a top-running crab trolley. It gives maximum hook height and the strength for heavy loads, large spans, an operator cabin and an auxiliary hoist.

What capacity can you supply?

Up to 250 tonnes, with spans up to 50 m and lift heights up to 100 m, in duty classes M1 to M8. Send your load, span and duty cycle and we’ll configure it.

When should I choose double over single girder?

Choose double girder above ~20 t, for spans beyond ~25 m, for maximum hook height, an operator cab, an auxiliary hoist, or heavy continuous M7 / M8 duty.

Can it have a second (auxiliary) hoist?

Yes — a main plus auxiliary hoist is common on double-girder cranes for handling two load ranges or for tilting / turning.

Do you offer weld radiography?

Yes — 100% radiography of bridge and end-carriage butt welds is available on request, in addition to the standard 125% load test.

Which standards apply?

IS 3177, IS 807 and IS 4137, with ISO 9001:2015 and ZED Gold certification.
