20 Tons Gantry Crane Technical Specifications

Core Features & Advantages

• ◆ Superior Load-Bearing Capacity: Built with a high-strength steel frame and reinforced lifting mechanism, the 20 tons gantry crane ensures stable operation under full load, effectively preventing deformation or failure during heavy lifting tasks. The main beam adopts a box girder or truss structure, fabricated via submerged arc automatic welding and shot blasting treatment to relieve stress, further enhancing structural strength and precision.
• ◆ Flexible & Convenient Operation: Equipped with multiple control modes, including pendant control, wireless remote control, and optional driver’s cab operation, the crane offers flexible operation options to adapt to different working scenarios. The wireless remote control allows operators to control the crane from a safe distance, reducing labor intensity and improving operational safety, while the variable frequency drive (VFD) system enables smooth lifting, lowering, and horizontal movement with adjustable speeds.
• ◆ Durable & Weather-Resistant: Constructed with corrosion-resistant materials, sealed components, and epoxy zinc-rich paint coating (film thickness exceeding 120 μm), the crane is suitable for both indoor and outdoor use, including harsh industrial environments, coastal areas, and regions with extreme temperatures (-20℃ ~ +50℃). The IP44-IP67 protection class ensures reliable operation even in dusty, humid, or rainy conditions.
• ◆ Precision Positioning & Energy Efficiency: Advanced hydraulic or electric drive systems minimize vibration during operation, ensuring accurate load placement with high precision – critical for tasks requiring precise alignment, such as machinery assembly and container handling. The optimized motor and transmission system reduce power consumption significantly, lowering operational costs while maintaining high performance levels.
• ◆ Easy Maintenance & Long Service Life: The crane features a user-friendly design with easily accessible components, allowing for quick disassembly, inspection, and maintenance. High-quality parts, including anti-wear roller bearings, centrifugal casting drums, and 10.9-grade high-strength bolts, extend the service life and reduce downtime, ensuring long-term stable operation.

Available Types

We offer multiple types of 20 tons gantry cranes to meet the unique needs of different industries and working scenarios, each with distinct features and advantages:

20 Tons Gantry Crane

• ◆ Single Girder 20 Tons Gantry Crane: Features a compact structure, light weight, and cost-effectiveness, ideal for light to medium-duty operations in warehouses, small ports, and concrete beam yards. Equipped with an electric hoist, it is easy to install and suitable for sites with limited headroom or budget constraints.
• ◆ Double Girder 20 Tons Gantry Crane: Equipped with two parallel main beams, offering higher stability, load-bearing capacity, and lifting height. Suitable for heavy-duty operations in ports, shipyards, large manufacturing plants, and mining areas. It can support additional attachments such as maintenance platforms, operator cabins, and lighting systems.
• ◆ Semi-Gantry 20 Tons Gantry Crane: With one leg on the ground and the other end fixed to an elevated runway, it saves space and cost by utilizing existing building structures. Ideal for workshops, warehouses, or production lines with limited space.
• ◆ Truss 20 Tons Gantry Crane: Adopts a triangular truss frame girder, reducing weight and wind resistance while maintaining high strength. Perfect for outdoor applications with large spans, such as logistics yards and construction sites, where wind loads are a concern.

20 Tons Gantry Crane Applications

The 20 tons gantry crane is widely used across various industries, thanks to its versatility and reliability. Key application scenarios include:

• ◆ Manufacturing Industry: Lifting heavy machinery, steel components, auto parts, and aerospace components in production lines and workshops.
• ◆ Ports & Terminals: Loading and unloading containers, bulk goods, and equipment from ships, trucks, and trains.
• ◆ Construction Sites: Hoisting steel beams, precast concrete panels, bridge construction machinery, and other heavy materials for infrastructure projects.
• ◆ Warehouses & Logistics Centers: Moving heavy pallets, industrial materials, and oversized goods in indoor and outdoor storage areas.
• ◆ Mining & Metallurgy: Handling ores, metal ingots, and smelting equipment in mines and steel plants.
