Double-Girder Gantry Crane

Double-Girder Gantry Crane
Double Girder Gantry Crane for Heavy-Duty Industrial Applications
The Double Girder Gantry Crane is engineered for demanding heavy-duty lifting
operations, offering outstanding load capacity, structural stability, and long-
term operational reliability. As an advanced form of Electric Gantry Crane,
this system is widely applied in large-scale logistics yards, shipyards, steel
plants, and infrastructure projects where high lifting performance and outdoor
adaptability are essential.
With lifting capacities ranging from 5 to 900 metric tons, double girder
gantry cranes are designed to handle oversized, heavy, and irregular loads
safely and efficiently under continuous working conditions.
 
Product Overview
A Double Girder Gantry Crane features two main girders supported by rigid
portal legs traveling on ground rails. The hoisting trolley runs on top of the
girders, enabling higher lifting heights, improved load distribution, and
enhanced operational stability compared to single girder gantry cranes.
This configuration makes it ideal for environments where overhead cranes are
impractical or where wide spans and outdoor operation are required.
