SAC40000T: World’s First 4000-Ton All-Terrain Crane Sets New Standards in Wind Power Installation
Historic Achievement: SAC40000T Completes Inaugural Lift in Gansu Wind Project
The SAC40000T, recognized as the world’s first nine-axle 4,000-ton all-terrain crane, has successfully completed its groundbreaking inaugural lift at the 200,000-kilowatt wind power project in Pingchuan, Baiyin, Gansu Province. This landmark achievement, accomplished in November 2023, represents a significant milestone in heavy lifting technology and renewable energy infrastructure development.
Currently owned and operated by Zhejiang Hesheng Hoisting Company, the revolutionary SAC40000T demonstrated exceptional performance capabilities and operational flexibility throughout the challenging project execution. The crane’s successful deployment in this complex environment underscores its position as a technological leader in the heavy lifting equipment industry.
The SAC40000T’s innovative design and engineering excellence were specifically showcased during the installation of advanced wind turbine technology in one of China’s most demanding geographical locations. This successful application establishes new benchmarks for crane performance in renewable energy projects worldwide.

Conquering Extreme Site Challenges
The wind power project presented extraordinary challenges that demanded the unique capabilities of the SAC40000T all-terrain crane. The installation involved a sophisticated 6.25MW wind turbine system with an impressive hub height of 120 meters, requiring precision engineering and exceptional lifting capacity.
The nacelle component alone weighed 150 tons, with the total lifting weight reaching 180 tons when including comprehensive rigging equipment. While this substantial load was well within the SAC40000T’s operational capacity, the primary reason for selecting this specific crane was its revolutionary nine-axle maneuverability system.
Project Manager Du Weihui emphasized the strategic decision: “With its exceptional lifting capacity and unparalleled flexibility, the SAC40000T proved to be the ideal solution for this complex site. The crane’s ability to operate efficiently in confined spaces was crucial for project success.”
Navigating Complex Terrain Conditions
The project site, located in a challenging mountainous region characterized by steep slopes and sharp turns, presented significant logistical and operational obstacles. The turbine tower center was positioned merely 40 meters from a cliff edge, requiring the SAC40000T to execute precise maneuvers within an extremely limited workspace.
The SAC40000T’s advanced engineering enabled it to overcome these geographical constraints through its compact dimensions and superior turning capabilities. The crane’s intelligent design allowed for safe and efficient operation in conditions that would typically preclude conventional lifting equipment.
The successful navigation of these challenging conditions demonstrates the SAC40000T’s capability to transform project feasibility in geographically constrained environments, opening new possibilities for renewable energy development in previously inaccessible locations.

Unprecedented Operational Efficiency
The SAC40000T demonstrated extraordinary efficiency metrics throughout the project execution, establishing new industry standards for heavy lifting operations. The crane’s superlift system was assembled in just one hour, a remarkable achievement that Equipment Manager Zhang Jie described as exceptional for initial deployment.
Zhang Jie further commented, “This was our first experience assembling the SAC40000T superlift system, and we achieved the one-hour target. With growing familiarity, we’re confident future assemblies will require even less time, further enhancing our operational efficiency and project turnaround capabilities.”
The crane’s lifting performance set remarkable benchmarks, with the fifth tower section hoisting completed in only 14 minutes and the nacelle installation accomplished in just 19 minutes. These efficiency metrics represent significant advancements in wind turbine installation speed and precision.
Advanced Mobility and Transport Capabilities
The SAC40000T’s mobility features were specifically engineered for demanding terrain conditions, supporting various transport configurations that minimize disassembly requirements during site transitions. For this project, the crane transported its outriggers, the first two boom sections, and the telescopic cylinder while navigating challenging route conditions.
The crane successfully traversed 2.5 kilometers of continuous S-curves with maximum gradients reaching 30%, demonstrating exceptional stability and power in conditions that would immobilize conventional lifting equipment. This capability significantly reduced the time-intensive disassembly and reassembly processes typically required during equipment relocation.
The integrated transport system enables the SAC40000T to maintain operational readiness while moving between project sites, providing substantial time savings and enhanced project scheduling flexibility for complex installation projects.
Industry Expert Endorsements and Feedback
General Manager Sun Lei of Zhejiang Hesheng Hoisting Company provided compelling insights regarding the SAC40000T’s performance: “The nine-axle crane with large booms demonstrates exceptional flexibility, particularly in challenging mountainous areas like this project site. Even within severely limited workspace constraints, the crane was fully assembled in just four hours.”
Sun Lei further emphasized the user-friendly design elements: “The SAC40000T’s intuitive engineering saves substantial assembly time, with the superlift system requiring only one hour for two superlift components. This efficiency directly translates into cost savings and enhanced project viability for complex installations.”
Project stakeholders universally praised the SAC40000T’s combination of raw power and precision control, noting that the crane’s performance exceeded expectations across all operational parameters. The successful project completion has generated significant industry interest in the SAC40000T’s capabilities for future renewable energy projects.
Transforming Renewable Energy Infrastructure Development
The successful deployment of the SAC40000T at the Gansu wind power project represents a transformative development for renewable energy infrastructure worldwide. The crane’s ability to operate efficiently in geographically challenging locations expands the potential for wind farm development in previously inaccessible regions.
As wind turbine technology continues to advance toward larger capacities and taller hub heights, the demand for sophisticated lifting equipment like the SAC40000T will continue to grow. The crane’s 4,000-ton capacity and precision control systems position it as an essential tool for next-generation wind energy projects.
The SAC40000T’s demonstrated capabilities in mountainous terrain suggest significant implications for global renewable energy strategies, potentially enabling wind farm development in diverse geographical locations that were previously considered economically or technically unfeasible.
