Double girder gantry crane is a heavy-duty lifting equipment widely used in industrial material handling applications. Compared with single girder gantry cranes, it offers stronger load-bearing capacity, larger span, and better overall stability, making it suitable for handling large and heavy materials in demanding working environments. Due to its robust dual-girder structure, the crane can achieve higher lifting performance and more stable operation during continuous heavy-duty work.
The crane mainly consists of the gantry structure, trolley travelling mechanism, crab travelling system, hoisting mechanism, and electrical control system. According to different application requirements, the crane can adopt various power supply methods, including cable reel power supply, diesel generator power supply, and bare copper slip line power supply. Double girder gantry cranes are commonly designed with box girder structures for higher strength and durability, although truss girder designs are also available for certain applications.
Double girder gantry cranes are widely used in precast concrete yards, shipbuilding industries, mining maintenance operations, bridge construction projects, warehouses, and other heavy lifting applications. As a professional gantry crane manufacturer, we can provide customized double girder gantry crane solutions with different capacities, spans, and configurations to meet various industrial lifting requirements.
Features
♦Strong and Stable Structure
The double girder gantry crane adopts a robust dual-girder structure that provides excellent load distribution and structural stability. Compared with single girder designs, the double girder configuration effectively reduces deflection and vibration during operation, ensuring smoother lifting performance under heavy loads and long-span working conditions. Its high-strength steel structure allows the crane to maintain reliable and stable operation even in demanding industrial environments such as factories, warehouses, shipyards, and construction sites.f
♦Precise and Smooth Handling
Equipped with an optimized trolley and travelling system, the double girder gantry crane delivers accurate positioning and smooth movement during lifting operations. The stable running mechanism helps improve material handling efficiency while reducing impact and mechanical wear on the hoist and other key components. Precise operation is especially beneficial for applications requiring careful positioning of heavy materials, machinery, or large workpieces. This efficient performance also contributes to extending the overall service life of the equipment.
♦Advanced Safety Protection
Safety is an important advantage of the double girder gantry crane. The crane is equipped with multiple protection devices, including overload protection, emergency stop systems, travelling limit switches, anti-sway functions, and safety monitoring devices. These integrated safety features help minimize operational risks and protect both operators and valuable cargo during lifting operations. The stable structure and reliable control system further ensure safe performance during continuous and high-intensity work.
♦Energy Saving and Low Maintenance
The crane combines high-strength construction with optimized mechanical design to reduce energy consumption during operation. High-quality electrical and mechanical components help lower maintenance frequency and minimize downtime, reducing long-term operating costs for customers. With its durable structure, efficient performance, and low maintenance requirements, the double girder gantry crane provides a cost-effective lifting solution for various industrial applications.
Factors Affecting Price
♦Lifting Capacity: The lifting capacity is one of the most important factors affecting the price of a heavy duty gantry crane. Cranes designed for heavier lifting operations require stronger steel structures, more powerful hoisting systems, and higher-grade components, which increase manufacturing costs. As the lifting tonnage increases, the overall design and safety requirements also become more demanding, resulting in higher equipment prices.
♦Span Length: The span of the heavy duty gantry crane directly influences the amount of steel material and structural strength required. A larger span requires a stronger and more stable double girder structure to ensure safe operation and reduce deflection during lifting. Because wider spans involve more engineering work, material consumption, and production complexity, cranes with larger spans are generally more expensive.
♦Lifting Height: The required lifting height also affects the final crane price. Higher lifting heights usually require longer wire ropes, larger drum systems, and more advanced hoisting mechanisms. Additional structural reinforcement may also be needed to maintain stability and safety during operation. Therefore, cranes with greater lifting heights often have higher production and installation costs.
♦Customization Requirements: Customized configurations and optional features can significantly impact the overall price of a heavy duty gantry crane. Special requirements such as explosion-proof systems, frequency conversion control, remote control operation, anti-sway technology, automated functions, or customized power supplies will increase equipment costs. Different working environments and application needs may also require tailored structural designs and additional safety devices.
♦Component Quality and Brand: The quality and brand of electrical components, motors, reducers, hoists, and control systems also influence crane pricing. High-quality components generally provide better performance, longer service life, and lower maintenance costs, but they also increase the initial investment cost of the crane.
♦Market and Material Factors: Market conditions, raw material prices, transportation costs, and supply chain fluctuations can also affect heavy duty gantry crane prices. Changes in steel prices, shipping expenses, and global market demand may lead to variations in production costs and final quotation prices over time.
