Global Success: Single-Girder Gantry Crane Case Studies

Thailand Logistics Center: MGO-Type 10-Ton Gantry Crane

In June 2024, Dongqi Crane customized an MGO-type 10-ton single-girder gantry crane and grab equipment for a large logistics center in Thailand. The center handles over 500 tons of goods daily, facing challenges of limited space but high cargo throughput.

Dongqi’s solution adopted a compact single-girder design, with a main girder height of only 1.2 meters, significantly reducing building clearance requirements and allowing the logistics center to maximize warehouse height for additional storage racks. The electric hoist was equipped with a variable frequency control system, enabling stepless speed adjustment from 0.8 to 8 m/min, ensuring smooth and precise lifting.

After deployment, the center’s cargo handling efficiency improved by 40%, while equipment energy consumption decreased by 15% compared to the original system, with an estimated payback period of 18 months.

Philippines Port: MGO + MHO Gantry Crane Combination

In 2024, Dongqi Crane provided a batch of customized gantry cranes for a long-term port client in the Philippines. The port primarily handles construction materials and light industrial products, requiring equipment suitable for both indoor warehouses and open storage yards.

Dongqi designed an MGO + MHO combination solution: MGO-type single-girder gantry cranes for indoor warehouse operations and MHO-type cranes for open storage yards. All equipment metal structures were coated with an 80μm-thick anti-corrosion layer, ensuring durability in high-temperature, high-humidity environments.

The outdoor equipment’s windproof and anti-slip systems were specially reinforced, with an anti-tipping coefficient of 1.5, far exceeding the industry standard of 1.2. Operational data showed that after two years of use, the metal structure corrosion rate was less than 8%, significantly lower than the industry average of 30%, with maintenance costs reduced by 60%.

Mongolia Construction Materials Factory: HD-Type 5-Ton European Single-Girder Crane

In June 2024, Dongqi Crane delivered three HD-type 5-ton European single-girder gantry cranes to a construction materials factory in Mongolia. The factory primarily produces prefabricated building components, with each piece weighing 1-3 tons and requiring over 200 lifting operations daily.

Dongqi’s solution adopted European crane design principles, minimizing the hook-to-wall distance and clearance height compared to traditional cranes. This design increased the workspace’s effective area and lifting height.

The equipment was equipped with a wireless remote control system, allowing operators to move freely within the work area, avoiding blind spots and improving safety. After four months of operation, data showed a 35% increase in production efficiency, a 90% reduction in product damage during transit, and an equipment failure rate of only 0.15 incidents per year.

Industry Applications: The Versatile Value of Single-Girder Gantry Cranes

Warehousing & Logistics: Space Optimization and Efficiency Improvement

In warehousing and logistics, single-girder gantry cranes stand out for their compact structure and low clearance requirements, making them ideal for maximizing space utilization. Compared to double-girder equipment, single-girder designs occupy 30% less space, enabling warehouses to install taller racks and increase storage capacity by 40%.

Dongqi Crane’s European single-girder gantry cranes can be seamlessly integrated into automated picking systems, working with WMS (Warehouse Management Systems) to enable automated order processing and precise inventory management. Their high-precision positioning (error ≤ 3mm) ensures safe and efficient placement of goods, reducing manual handling errors.

Construction Materials Industry: Heavy-Duty Handling and Durability

The construction materials industry often involves outdoor storage and transportation of long-sized materials such as pipes and profiles, placing high demands on equipment span and weather resistance. Dongqi Crane’s single-girder gantry cranes offer a maximum 38m span, covering standard construction material storage areas. A single lift can handle six 6m-long pipes, improving loading/unloading efficiency by 50%.

To address the dusty and humid conditions typical in construction material plants, Dongqi’s equipment uses Q345B low-alloy steel for the main girder, with a yield strength of 345MPa—18% lighter than traditional steel. Special anti-corrosion treatment (80μm coating thickness) ensures excellent long-term corrosion resistance in outdoor environments.

Light Industry & Production Workshops: Flexible Layout and Cost Control

In small and medium-sized machinery factories and light industrial workshops, Dongqi’s single-girder gantry cranes demonstrate advantages in flexible layout and cost-effectiveness. Their lightweight leg design (box structure, 350mm × 250mm cross-section) reduces ground foundation requirements and simplifies installation with anchor bolt fixation.

The procurement cost is 35% lower than double-girder gantry cranes with similar specifications, while operating energy consumption is reduced by 12%. A case study from a hardware factory showed that the cost difference compared to traditional double-girder equipment was recovered in just 1 year, while fully meeting daily production needs.
