Product Introduction
Double Girder Gantry Crane is a heavy-duty material handling system featuring two parallel main girders supported by robust A-frame legs that travel along ground-level rails. Engineered for exceptional stability, ultra-high lifting capacities, and large spans, it serves as an indispensable workhorse for heavy lifting operations in outdoor stockyards, ports, shipyards, railway freight terminals, and major construction projects.

Product Advantages
Heavy-Duty Performance
Delivers superior load-bearing capacity and high working duty classes, effortlessly handling bulky, heavy, or complex loads.
Versatile Trolley System
The hoisting trolley runs along tracks mounted on top of the two main girders, providing exceptional structural rigidity, smooth lateral travel, and generous lifting height.
Flexible Cantilever Options
Available with single or double-sided cantilevers (overhangs) to extend hook reach beyond the rail span, streamlining cargo transfers to trucks, train cars, or staging areas.
Advanced Control Options
Supports ground pendant control, wireless remote control, or fully enclosed ergonomic operator cabins with wide visibility, ensuring precise and safe load positioning.
Typical Application Scenarios
MG-Type Double Girder Hook Gantry Crane
Widely deployed in open-air warehouses, material yards, railway freight hubs, and port terminals for general loading, unloading, and stacking operations.
Specialized Attachment Support
Can be customized with various specialized spreaders—such as motor-driven grabs for bulk cargo, electromagnets for steel scrap/plates, container spreaders, or C-hooks for steel coils—to meet complex industrial workflow requirements.
