Weihua's independently developed 550-ton double-girder U-type gantry crane has successfully completed full-load testing at a construction site in Guangdong, China. With a rated lifting capacity of 550 tons and a 10-meter trolley gauge, this crane represents the largest-capacity double-girder U-shaped gantry crane ever manufactured by Weihua, marking another milestone in the company's heavy-duty lifting technology.
Specifically designed for demanding construction and infrastructure projects, the crane delivers exceptional lifting performance, precise load control, and long-term operational reliability under heavy working conditions.
Key Technical Highlights
Dual Main Hoisting System
The crane is equipped with two independent 275-ton main hoists, which can operate individually or synchronously according to different lifting requirements. An intelligent synchronization control system ensures accurate and coordinated lifting and lowering, improving both operational efficiency and safety.
Intelligent Variable Frequency Control
All major operating mechanisms adopt variable frequency drive (VFD) technology combined with a PLC-based intelligent control system. The crane provides stepless speed regulation under both full-load and light-load conditions, ensuring smooth acceleration, reduced mechanical impact, low operating noise, and precise load handling.
Lightweight Structural Engineering
The entire crane adopts an optimized lightweight structural design developed through finite element analysis (FEA). This engineering approach guarantees excellent structural strength and rigidity while reducing overall dead weight, wheel loads, and energy consumption. The compact configuration further improves operating efficiency and lowers maintenance costs.
Optimized Traveling Mechanism
The traveling system features a multi-stage equalizing beam and bogie arrangement, while articulated hinge connections distribute wheel loads evenly across the rail system. This optimized design enhances traveling stability, minimizes wheel wear, and ensures smoother crane movement during long-distance operation.
Continuous Innovation in Heavy Lifting Technology
Driven by continuous technological innovation, Weihua has made significant advancements in high-capacity, intelligent, and energy-efficient lifting equipment. Its crane solutions have been widely applied in numerous landmark infrastructure projects, including Olympic venues, the West-to-East Gas Transmission Project, the South-to-North Water Diversion Project, and the Hangzhou Bay Bridge, demonstrating the company's strong engineering capabilities across multiple industries.
Committed to Sustainable Global Development
Looking ahead, Weihua will continue to strengthen its manufacturing capabilities by focusing on globalization, digitalization, intelligent manufacturing, and sustainable development. Leveraging its advanced technology and comprehensive industrial resources, the company remains committed to delivering safer, smarter, and more efficient lifting solutions for customers around the world while supporting the long-term development of the global manufacturing industry.
