Progress update on the world's first 658-meter ultra-high lifting crane!

Recently, Weihuaa special gantry crane for ultra-high lift shafts with a lifting height of 658 meters was officially put into use at the Songyang pumped storage power station in Zhejiang, helping the construction of the power station enter a new stage and contributing vigorous green energy to the local construction of a green, efficient and intelligent power system.

The water diversion shaft of Songyang Pumped Storage Power Station is 537 meters deep. Together with the water diversion and pressure regulating shaft directly above, it forms a shaft with a total height of 637 meters. It is the deepest 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. It provides an efficient and safe solution for engineering construction and can complete a series of ultra-high-lift safe lifting operations in the entire process of shaft construction and excavation.

Especially in key links such as slag extraction from the main shaft excavation of the upper pressure regulating shaft, installation and dismantling of the complete shaft boring machine, precise lifting of pressure steel pipes and fully automatic detachment of deep shafts, and safe and efficient transportation of construction personnel in the shaft, it has played an irreplaceable and important role.It has achieved full process coverage in the shaft construction process, demonstrating Weihua's outstanding strength in the field of ultra-large lifting equipment.

The crane is currently excavating the pressure regulating well

The technical engineer of the pumped storage power station said: "Weihua's 650-meter intelligent high-lift door 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 is a major breakthrough in the research and development of major equipment in my country's water conservancy and hydropower industry. ”

After the Songyang Pumped Storage Power Station is completed, it will undertake tasks such as peak shaving, valley filling, energy storage, frequency modulation, phase modulation and emergency backup for the Zhejiang power grid. It will further enhance the flexible dispatching capabilities of the East China Power Grid and is of great significance to building a new power system with new energy as the main body and ensuring energy security.

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