20 Tons Gantry Crane Technical Specifications

Fonctionnalités principales & Avantages

• ◆ Capacité de charge supérieure: Built with a high-strength steel frame and reinforced lifting mechanism, le 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, télécommande sans fil, 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, abaissement, 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 & Efficacité énergétique: 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, et entretien. 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, assurer un fonctionnement stable à long terme.

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 Grue à portique de tonnes

• ◆ Single Girder 20 Grue à portique de tonnes: Features a compact structure, light weight, et la rentabilité, 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 Grue à portique de tonnes: Equipped with two parallel main beams, offering higher stability, load-bearing capacity, and lifting height. Suitable for heavy-duty operations in ports, chantiers navals, large manufacturing plants, and mining areas. It can support additional attachments such as maintenance platforms, operator cabins, and lighting systems.
• ◆ Semi-Gantry 20 Grue à portique de tonnes: 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. Idéal pour les ateliers, entrepôts, or production lines with limited space.
• ◆ Truss 20 Grue à portique de tonnes: 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.
