Description
The Weihua A-type double-girder gantry crane is a core product in the Weihua Group's gantry crane series. Named for its A-shaped leg structure, it is a high-performance lifting device specifically designed for outdoor heavy-duty operations. As the most powerful and structurally stable model in the gantry crane family, it is widely used in ports, railway freight yards, open-air warehouses, wind power assembly bases, and various large-scale logistics transfer centers, undertaking critical tasks such as loading, unloading, handling, and stacking heavy materials.
In terms of product positioning, the A-type double-girder gantry crane covers an ultra-wide range of lifting capacities from 5 tons to 800 tons, spans from 6 meters to 50 meters, and working classes including A5, A6, and A7, meeting diverse needs from general loading and unloading operations to high-frequency heavy-duty conditions. This wide range of specifications makes it one of the most adaptable and widely used gantry crane products on the market.
In terms of structural design, the A-type double-girder gantry crane adopts a classic double-girder box-shaped welded structure, with the two legs extending outwards in an A-shape, forming a stable triangular support system. This structural layout offers two core advantages: first, strong anti-overturning capability, effectively resisting the effects of strong winds and other severe weather conditions in outdoor operations; second, excellent lifting stability, with the double main beams sharing the load and distributing stress evenly, ensuring that heavy objects do not sway or shift during lifting.
The Weihua Type A double-girder gantry crane strictly adheres to a lightweight and modular design philosophy, supported by computer-aided design and finite element analysis. It is manufactured using high-strength steel and new processes, optimizing the overall weight while ensuring structural strength. This product comes standard with a variable frequency speed control system, enabling smooth starting and braking, precise positioning, easy operation, stable operation, and reliable safety.

Advantages
When purchasing a marine travel lift for sale, it is recommended to conduct a professional evaluation in the following four areas:
Superior Stability & Load Capacity
The A-shaped leg design, combined with two parallel box-type main girders, delivers exceptional bending and torsional rigidity, ensuring stability even under maximum load conditions. This structure supports lifting capacities from 5 up to 800 tons, making it ideal for the heaviest industrial duties.
Wide Span & Large Working Coverage
With two main beams, the crane achieves a wider span and greater lifting height compared to single-girder designs. This allows full coverage of large work areas—such as ports, stockyards, and mining sites—without requiring additional equipment.
Versatile Multi-Site Adaptability
Designed for both indoor and outdoor applications, the crane operates reliably in open-air environments, with options for truss-type beams that significantly reduce wind resistance and dead weight. Customizable features include multiple control modes (ground, remote, cabin), rail types, and corrosion protection for harsh conditions.
Heavy-Duty Durability & Low Maintenance
Built for continuous operation with work duty classifications up to A7, the crane features robust construction with high-quality materials such as 65Mn forged wheels and protective coatings. Modular design simplifies assembly, maintenance, and transport,
