The Double Girder Gantry Crane is a highly efficient lifting solution designed for large-span, heavy-duty material handling applications in open yards, logistics bases, and industrial plants. This project highlights the successful delivery of two customized double girder gantry cranes to a long-term customer in Kyrgyzstan, demonstrating both technical strength and reliable cooperation.
Project Background
This order was placed by an existing customer, reflecting long-term trust and satisfaction with previous equipment and service performance. The total production and delivery cycle was 30 working days, with transportation arranged by land freight under EXW terms. The destination country was Kyrgyzstan, and the payment terms were 50% T/T down payment and 50% T/T before delivery, ensuring a smooth and efficient transaction process.
The customer required gantry cranes capable of handling heavy loads over a wide working area, with stable operation, high safety standards, and precise speed control. Based on these requirements, two double girder gantry cranes with different lifting capacities were supplied under the same structural and control philosophy.
Standard Configuration Overview
The project included two sets of MG-type Double Girder Gantry Cranes, both designed to meet A5 duty class requirements for frequent and demanding operations:
-
Crane Type: Double Girder Gantry Crane
-
Model: MG
-
Working Class: A5
-
Rated Capacities:
-
12 tons × 1 set
-
16 tons × 1 set
-
-
Span: 32 m + 8.7 m + 8.7 m (with effective cantilevers on both sides)
-
Lifting Height: 11 meters
-
Operation Mode: Cabin control
-
Power Supply: 380V / 50Hz / 3 Phase
-
Quantity: 2 units
The 8.7-meter effective cantilevers on both sides significantly expanded the working coverage, allowing materials to be handled beyond the rail span, which is particularly valuable for outdoor yards and long-material handling.
Advanced Control and Speed Configuration
To meet the customer’s requirement for smooth and precise operation, all crane motions were equipped with VVVF (Variable Voltage Variable Frequency) control systems:
-
Hoisting Speed: 1–12 m/min (VVVF)
-
Trolley Traveling Speed: 5–60 m/min (VVVF)
-
Crane Traveling Speed: 6–60 m/min (VVVF)
VVVF control ensures soft start and stop, reduces mechanical impact, improves positioning accuracy, and extends the service life of mechanical components. This configuration is especially important for A5 working class cranes operating under frequent load cycles.
Operator-Oriented Cabin Design
Both double girder gantry cranes were designed with driver cabins as the primary control method. The cabins provide operators with a clear field of vision, ergonomic control layout, and a comfortable working environment for long shifts. Cabin operation is particularly suitable for large-span gantry cranes, where precise coordination and situational awareness are critical for safety.
Compliance and Trade Information
The cranes were classified under HS Code 8426194100, ensuring correct customs declaration and smooth cross-border logistics. In addition, the project included a customer commission of CNY 73,000, paid via a private Alipay account, which was handled transparently and efficiently as part of the overall transaction arrangement.
Key Advantages of the Double Girder Gantry Crane
The supplied double girder gantry cranes offer several core benefits:
-
High Load Capacity and Structural Stability
The double girder structure provides excellent rigidity and load distribution, ideal for heavy-duty lifting applications. -
Wide Working Range with Cantilevers
Dual 8.7 m cantilevers significantly increase operational flexibility and material handling efficiency. -
Precise and Smooth Operation
Full VVVF control on all movements ensures accurate positioning and reduced wear. -
High Safety and Reliability
Designed to A5 duty class, the cranes are suitable for frequent operation with long service life. -
Operator Comfort and Control
Cabin control enhances visibility, safety, and operational precision in large outdoor environments.
Conclusion
This project demonstrates how a well-designed Double Girder Gantry Crane solution can effectively meet demanding industrial requirements in terms of load capacity, span, control accuracy, and reliability. Through professional engineering, flexible configuration, and fast response to customer needs, the delivered gantry cranes provide long-term value and reinforce strong cooperation with the customer in Kyrgyzstan.
