20 Tons Gantry Crane Technical Specifications

الميزات الأساسية & المزايا

• ◆ قدرة تحمل متفوقة: Built with a high-strength steel frame and reinforced lifting mechanism, ال 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, جهاز تحكم عن بعد لاسلكي, 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, خفض, and horizontal movement with adjustable speeds.
• ◆ متينة & 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 (-20درجه مئوية ~ +50 درجه مئوية). The IP44-IP67 protection class ensures reliable operation even in dusty, humid, or rainy conditions.
• ◆ Precision Positioning & كفاءة الطاقة: 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, تقتيش, والصيانة. 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, ضمان عملية مستقرة على المدى الطويل.
