Description
Double Girder Gantry Crane
Product Overview and Highlights：
A double girder gantry crane is a heavy-duty lifting solution designed for outdoor and large-area material handling. As a variant of the bridge crane, it features two main girders supported by rigid gantry legs, offering high load capacity, wide span coverage, and excellent stability.
This type of crane is widely used in ports, cargo yards, large warehouses, construction sites, and bulk material handling areas where high working frequency and heavy loads are required. As one of the most reliable solutions offered by double girder gantry crane manufacturers, it delivers safe, efficient, and long-term lifting performance.
1.High lifting capacity up to 350 tons for demanding operations.
2.Wide span and large working range for maximum site utilization.
3.Stable double box girder structure with uniform load distribution.
4.Suitable for outdoor use with windproof and rail-clamping devices.
5.Supports advanced options such as anti-sway and automatic positioning.

Product Features and Applications：
1.Strong load capability: The double girder gantry crane handles heavy-duty lifting with excellent rigidity and stability.
2.Compact and durable structure: The double box girder gantry crane design reduces wheel pressure while maintaining strength.
3.Flexible operation: Lifting, cross travel, and long travel motions allow precise material positioning.
4.High safety level: Equipped with overload protection, limit switches, buffers, and emergency stop systems.
The double girder gantry crane is ideal for port cargo yards, docks, steel yards, large warehouses, hydropower projects, and construction sites. It is especially suitable for environments with heavy loads, high duty cycles, and long-span material handling requirements.
Product Details：
1.Main Beam: Welded box or truss-type girders provide high rigidity and strength, with built-in walkways for maintenance.
2.Gantry Legs: A-shaped or U-shaped welded steel structures ensure stability under vertical and horizontal loads.
3.Trolley System: Heavy-duty trolley with lifting mechanism, buffers, and limit devices for safe operation.
4.Crane Traveling Mechanism: Motor, reducer, and wheel sets with windproof rail clamps for outdoor conditions.
5.Control Mode: Cabin control, pendant control, or wireless remote control available.
