Double Trolley Overhead Crane

As a professional heavy-duty lifting equipment, the double trolley overhead crane (also known as double trolley bridge crane) is engineered to meet the complex and high-demand lifting requirements of various industrial scenarios. Equipped with two independent or collaborative trolleys, this industrial double trolley overhead crane significantly enhances operational flexibility, بهره وری, و دقت, making it an indispensable core equipment in large-scale factories, پورت ها, انبارها, and infrastructure construction sites. Whether it is for synchronous lifting of oversized workpieces, separate handling of multiple loads, or coordinated operations in limited space, our high performance double trolley overhead crane delivers reliable and high-performance lifting solutions.

ویژگی های اصلی & Advantages of Heavy Duty Double Trolley Overhead Crane

• 1. Dual Trolley Collaborative/Independent Operation: The double trolley overhead crane is equipped with two independently controlled trolleys that can operate separately or synchronously. Independent operation enables simultaneous handling of two different loads at different positions, improving work efficiency; synchronous operation allows for stable lifting of extra-long, extra-heavy, or irregular workpieces (such as large steel beams, ship segments, and heavy machinery components), ensuring balanced force and preventing workpiece deformation. This unique design is what distinguishes the double trolley overhead crane from single trolley models.
• 2. High Load-Bearing Capacity & Stable Structure: Adopting high-strength steel for the main beam and trolley frame, the crane undergoes strict structural optimization and load-bearing tests. The box-type main beam design enhances rigidity and reduces deflection, ensuring stable operation even under full-load conditions. The load-bearing capacity ranges from 10 تن جرثقیل سقفی به 1200 تن جرثقیل سقفی, and can be customized according to specific industrial needs.
• 3. Precision Positioning & عمل صاف: Equipped with advanced frequency conversion speed regulation system and high-precision guiding mechanism, the crane realizes stepless speed regulation of trolley and bridge operation. This not only ensures smooth start-up, braking, and movement, but also achieves precise positioning of loads (positioning accuracy up to ±5mm), which is suitable for high-precision assembly, processing, and hoisting scenarios.
• 4. Comprehensive Safety Protection System: The crane is configured with multiple safety protection devices, از جمله حفاظت از اضافه بار, overtravel limit, توقف اضطراری, voltage loss protection, و دستگاه های ضد برخورد (between trolleys and between crane and workshop walls). The electrical system adopts waterproof, dustproof, and anti-interference designs, ensuring safe and reliable operation in harsh industrial environments. All safety performance indicators comply with international standards such as ISO and FEM.
• 5. Energy-Saving & تعمیر و نگهداری آسان: The optimized transmission system and high-efficiency motor reduce energy consumption by 15-20% compared to traditional cranes. The key components (such as motors, کاهنده ها, و ترمز) adopt well-known brand products, with standardized interfaces and easy access for maintenance. The crane is also equipped with a fault diagnosis system that can timely alarm and display fault information, reducing maintenance time and costs.
