World's First 250,000 Tonne-Meter Ring Crane Rolls Off Production Line, Supporting Hualong One 2.0 Nuclear Power Construction

On August 31, the world's first 250,000 tonne-meter ring crane, jointly developed by SANY Heavy Lift and China Energy Engineering Group Guangdong Thermal Power & Litte Company, rolled off the production line at SANY's Huzhou Industrial Park in Zhejiang. Designed for the "one crane, two islands" construction requirements of Hualong One 2.0, the equipment can address the engineering challenge of covering module hoisting for two nuclear islands with a single unit, marking a key domestic localization breakthrough in China's ultra-large-tonnage nuclear power hoisting equipment.

With the advancement of the Hualong One 2.0 "one crane, two islands" construction method, nuclear power projects have imposed higher requirements on the working radius, load capacity, and hoisting precision of heavy lifting equipment. In the past, related high-end equipment technology was long controlled by a few overseas companies. The 250,000 tonne-meter ring crane rolled off the production line this time has undergone seven years of technical research, achieving breakthroughs in structural design, manufacturing processes, and assembly control.

The equipment features a super-long boom combination of 137 meters plus 66 meters, with a maximum height of 207 meters. According to the developer, under medium-to-large radius conditions in nuclear power applications, its lifting capacity is approximately 50% higher than that of comparable foreign products, enabling it to meet relevant hoisting requirements from a single position and under a single working condition.

In terms of operation, the equipment adopts an all-electric drive mode and can be directly connected to industrial mains power, featuring zero emissions and low noise. According to project estimates, the application of this equipment is expected to shorten nuclear power project construction periods by 15%, with operating costs approximately one-quarter of those of traditional fuel-powered equipment, and site and logistics costs reduced by 20% and 30%, respectively.

In terms of safety control, the equipment is equipped with digital systems including intelligent anti-collision, 360° surround view, remote fault diagnosis, rope tangle detection, facial recognition, and operation behavior recognition, enhancing risk identification and protection capabilities during on-site hoisting operations. Following its rollout, the equipment will provide domestic heavy-lifting support for subsequent Hualong One 2.0 project construction.
