Weihua High-Specific-Gravity Vertical Shaft Specialized Crane
The vertical shaft dedicated gantry crane is the core equipment for deep vertical shaft construction in pumped storage power stations, undertaking critical missions such as shaft excavation, steel pipe hoisting, equipment conveyance, and safe personnel lifting.
This equipment pioneered the "dual parallel zigzag drum + traction-type constant offset arrangement" technology, successfully overcoming the technical bottleneck of multi-layered, orderly wire rope winding under an ultra-deep headway of 650 meters. It integrates 5G communication, UWB positioning, and AI technologies to achieve centimeter-level dynamic positioning and intelligent collaborative control in underground environments. Designed for both passenger and cargo operations, it innovatively features a "three-level braking + dual-rope redundancy" multi-layer safety protection system and a hoist cage life support device, meeting elevator-grade safety standards.
In the Songyang Pumped Storage Power Station project in Zhejiang, Henan Weihua customized the world's first 700-meter-class ultra-deep shaft hoisting-integrated intelligent specialized equipment, achieving comprehensive coverage of the entire shaft construction process. It played an irreplaceable role in key stages such as the excavation and slag removal of the upper section pressure relief shaft, the assembly and disassembly of the shaft boring machine inside the shaft, the precise hoisting of pressure steel pipes, fully automated detachment and hanging in deep shafts, and the efficient and safe transportation of construction personnel within the shaft. This significantly enhanced the efficiency and safety of ultra-deep narrow shaft operations, demonstrating Weihua's outstanding technical expertise in the field of super-large lifting equipment.
As a leading enterprise in the heavy equipment manufacturing industry, Henan Weihua leverages its industry-leading equipment matrix, including a 1,000-ton-class super-large type test bench, a 3D vision intelligent bevel cutting robot, and a 500-ton-class large structural component annealing furnace, to break through the entire process barriers from raw material processing to finished product inspection.
Every stage of production and processing integrates high-precision manufacturing genes and intelligent control logic, forming a manufacturing advantage characterized by "strong equipment, refined processes, and strict control." The machining accuracy of ultra-large structural components reaches the top tier of the industry, while the intelligent production line flexibly adapts to multi-category orders.
