Recently, the Weihua lifting gantry crane with a height of 658 meters and a super high lift vertical shaft was officially put into use at the Songyang Pumped Storage Power Station in Zhejiang Province, helping the construction of the power station enter a new stage and contributing vigorous green energy to the construction of a green, efficient, and intelligent power system in the local area.

The water intake shaft of Songyang Pumped Storage Power Station is 537 meters deep, forming a total height of 637 meters with the water intake and pressure regulating shaft directly above, making it the deepest vertical shaft in domestic water conservancy and hydropower projects.

The Weihua ultra-high lift gantry crane used in this project has become the world's first set of equipment with a lifting height of 658 meters, providing an efficient and safe solution for engineering construction. It can complete a series of ultra-high lift safe lifting operations during the entire process of vertical shaft construction and excavation.

Especially in the excavation of the upper section of the pressure regulating shaft, the installation and removal of the vertical shaft boring machine, the precise lifting of pressure steel pipes and the fully automatic detachment of deep wells, and the safe and efficient transportation of construction personnel in the well, these key links have played an irreplaceable and important role, achieving full process coverage in the construction of vertical wells and demonstrating Weihua's outstanding strength in the field of ultra large lifting equipment.

The technical engineer of the pumped storage power station said, "The Weihua 650 meter intelligent high lift gantry crane is equipped with various sensing systems such as video positioning, 5G remote monitoring, and environmental monitoring. It has functions such as one click positioning, path planning, and intelligent anti sway. The level of intelligence is second to none in the industry, and it is a major breakthrough in the research and development of major equipment in China's water conservancy and hydropower industry

After the completion of the Songyang Pumped Storage Power Station, it will undertake tasks such as peak shaving, valley filling, energy storage, frequency regulation, phase regulation, and emergency backup for the Zhejiang power grid, further enhancing the flexible scheduling capability of the East China power grid. This is of great significance for building a new power system with new energy as the main body and ensuring energy security.

The smooth operation of Weihua's 658 meter ultra-high lift lifting equipment is not only a strong support for Weihua's implementation of key national projects during the 14th Five Year Plan period, but also an important achievement of Weihua's innovative technological strength in helping to build a national new energy system. In the future, Weihua will continue to uphold the concept of "customer first, creating value", continuously strengthen technological iteration and innovation, continuously improve the high-end product matrix, help achieve the "dual carbon" goal, and contribute more strength to the national new energy green transformation and development.
