Groupe Weihua is one of China's largest crane manufacturers, with over 30 years of experience in the industry, exporting its products to more than 100 countries and regions worldwide. Single-girder gantry cranes (also known as single-girder portal cranes) are one of Weihua's core products, widely used in various scenarios such as outdoor material yards, factory workshops, logistics warehouses, and railway freight yards.
Weihua's single-girder gantry cranes have lifting capacities ranging from 2 tons to 32 tons, spans from 5 to 35 meters, and maximum lifting heights from 6 to 24 meters. All parameters can be customized to meet customer needs. The products comply with GB and FEM/ISO international standards and have obtained CE certification, meeting global export requirements.
A single-girder gantry crane consists of a single main girder, two side legs, end beams, a traveling mechanism, and an electrical system. The electric hoist travels along the lower flange of the main girder, achieving precise lifting in three-dimensional space. Compared to double-girder gantry cranes, the single-girder structure is lighter, less expensive, and easier to install, making it the preferred choice for medium to light load applications.
Understanding the key components helps you specify the right crane for your application. A single girder gantry crane is composed of the following main assemblies:
The MH box-type single girder gantry crane is Weihua's best-selling general-purpose product. It features a welded box-type main girder, offering high rigidity and smooth operation, making it suitable for daily lifting operations in factory stockyards, freight yards, and outdoor storage areas.
Caractéristiques principales :
High torsional rigidity of the box-type main girder, long fatigue life.
Standard configuration includes Weihua CD1/MD1 wire rope electric hoist.
Optional single or double cantilever for expanded working range.
Corrosion protection options include hot-dip galvanizing or epoxy coating to adapt to corrosive environments.
Suitable for outdoor lifting operations with medium to light loads of 2-20 tons in factory workshops, outdoor freight yards, steel storage yards, timber yards, building material warehouses, etc.

The MH truss-type single beam gantry crane replaces the solid-web box girder with a triangular or rectangular welded truss, reducing overall weight by 20%–30% and decreasing windward area. This makes it particularly suitable for large spans (18 meters and above) and strong wind outdoor locations, while also reducing foundation construction costs.
Key Features
Truss structure: Lightweight and low wind load; overall cost is superior to box girder for large spans.
Suitable for high-wind-speed open-air environments such as seaside and coastal areas; anti-corrosion coating optional.
Can be equipped with single or double cantilever arms to increase coverage area.
Open-air storage yards, timber/pipe storage, bulk cargo yards, port auxiliary operation areas, and other large-span outdoor heavy-duty scenarios.

The L-type gantry crane is a flexible and efficient single-beam gantry crane suitable for outdoor material handling. Its core structure includes the main beam, legs, and hoisting mechanism.
Key Features
• L-shaped leg structure provides greater lifting space and span capacity.
• The main beam uses a single-beam staggered rail design, facilitating the transfer of objects from the span to below the cantilever.
• Box-type gantry frame: robust structure, suitable for heavy-duty operations.
Manufacturing workshops, storage yards, auto repair shops, precast concrete yards, logistics centers.

The BMH semi-gantry crane runs along a ground track on one side and travels along an elevated track on the other side using the building's walls or columns. This maximizes the use of ground space, reduces construction costs, and is suitable for factories with load-bearing structures.
Key Features
• Single-sided ground track + single-sided elevated track, lower construction costs than a full gantry crane
• No outriggers obstructing the elevated side, resulting in more open ground space and easier logistics channel layout
• Weihua provides a complete solution: crane + track + foundation design + installation guidance
Manufacturing plants with reinforced concrete columns, metal processing workshops, truck loading and unloading platforms, and production lines where ground-level access does not allow for track installation on one side.
