U-Type Double Girder Outdoor Gantry Crane

Introduzione al prodotto

The U-type outdoor gantry crane double girder is mainly for general loading, unloading, and lifting operations. It has increased the design of the small trolley track gauge, resulting in a larger legroom and suitable for handling larger items like containers, etc. Due to its structure, this gantry crane eliminates the need for a saddle frame compared to the A-type gantry crane.

With a fixed lifting height, the overall height of the machine is lower than the A-type gantry crane. And the rail distance of its electric trolley is long, which means better operational stability and load distribution. All the design makes it an excellent performance and adaptable to multiple working sites. Its supporting legs increase stability and allow the equipment to move freely on the ground.

Applicazione

U-type outdoor gantry crane double girder is suitable for general loading, unloading, and lifting operations in open-air freight yards and along railway lines. The normal operating environment of this series of U-type double girder gantry cranes should be within the range of 25℃~+40℃. The average temperature within 24 hours should not exceed 135℃. The average temperature within 24 hours should not exceed 135℃.

At container terminals, U-type double girder outdoor gantry cranes could transfer containers from cargo ships to yards or trucks. They are capable of handling containers of different sizes and can be turned around quickly to increase efficiency. Besides containers, U gantry crane double girder can also load and unload bulk cargo, large machinery, and other heavy items.

In steel plants, timber mills, etc., U shape outdoor gantry crane double girder provides efficient lifting solutions for users.

parts of gantry crane

Outdoor gantry crane typically consists of the following main components:

• Main girder: also known as a large girder, carries hoists and loads over the span. Two types of single and double girders are available.
• Outriggers: Support frames, to connect the main beam to the ground and support vertical loads. It is designed as a box or A-frame and can be fixed or equipped with wheels to move around.
• Lifting mechanism: lifts and lowers the load. Can be equipped with CD/MD wire rope hoists, Euro hoists, or electric trolleys; single/double speed or variable frequency.
• End carriage/wheel: enables the crane to move along the track or yard. Adopt forged steel or cast steel wheels, equipped with a buffer and a derailment protection device to ensure the safety of outdoor operation.
• Crane traveling mechanism: drives the whole crane to move horizontally along the rail or ground. Including motor, reducer, and braking system; specially designed for outdoor conditions, with dustproof and waterproof protection.
• Electrical system: controls hoisting and traveling operations. Includes control panel, power cord, and braking system.
• Ground rail or rubber tire: supports the crane to move on the ground. Ground rail: suitable for fixed rail. Rubber tires: flexible movement without tracks

Types of Outdoor Gantry Cranes for Sale

Outdoor gantry cranes are the ideal lifting solution for open spaces and are widely used in material handling operations at construction sites, logistics stations, and manufacturing areas. They are specifically designed to withstand harsh weather conditions and heavy-duty operations, offering flexible configurations to suit a variety of application requirements. Depending on your operational needs and working environment, there are several outdoor gantry cranes to choose from, including:

Single Girder Outdoor Gantry Crane

Features a single main beam structure with an electric hoist operating beneath the main beam, typically in a simply supported configuration.

Applications: Suitable for outdoor material handling of medium to small tonnage, such as warehousing areas, equipment loading/unloading zones, construction sites, etc.
Advantages: Lightweight structure, low cost, easy installation, particularly suitable for limited space or temporary operational requirements.

Double Girder Outdoor Gantry Crane

Features a double main beam design, with an electric hoist or trolley operating between the two main beam tracks, offering strong overall load-bearing capacity.

Applications: Widely used in heavy-duty equipment handling, container yards, steel markets, and other high-intensity operation areas.
Key Advantages: High lifting capacity, wide span, and smooth operation, suitable for high-frequency, high-load professional operation requirements.

Rubber-Tyred Outdoor Gantry Crane

Trackless design with rubber tires for mobility, powered by diesel engines, electric motors, or hybrid drive systems.

Applications: Commonly used in container yards, shipyards, and precast component handling areas, capable of flexible movement to different work sites.
Advantages: High mobility, no need for fixed tracks, and flexible steering, suitable for large-area operations and frequent site transfers.

Semi- Type Outdoor Gantry Crane

One side operates on ground tracks, while the other is supported by elevated structures (such as factory building or wall tracks).

Applications: Commonly used for handling or loading/unloading operations in special layouts such as along factory building exteriors, workshop corridors, or assembly lines.
Advantages: Space-saving structure, suitable for asymmetric work areas, facilitates integration with factory building structures, and reduces civil engineering costs.
