Sany SAC12000

The Sany SAC12000 represents a milestone in China’s heavy lifting industry, marking a competitive step toward global dominance in high-capacity crane manufacturing. Its introduction at the 2010 China International Construction Machinery Exhibition signified China’s ambition to break the monopoly of European manufacturers like Liebherr in the ultra-heavy all-terrain crane segment. Originally developed under the model name SAC303, which has since been discontinued, the SAC12000 features cutting-edge engineering, high-strength materials, and advanced safety features to meet the demanding needs of industrial construction, wind energy projects, and high-rise infrastructure.

The crane’s eight-section telescopic boom reaches 102 meters (335 feet), providing impressive height capabilities for wind turbine installation and high-rise structural lifting. The jib extends from 18 to 126 meters (59 to 413 feet), allowing for versatile lifting configurations and optimized working ranges for complex projects. The minimum rated working radius of just 3 meters (9.8 feet) ensures efficiency in confined spaces, while its X-type, swing-out, and telescopic hydraulic outriggers offer superior stability and automatic leveling for safe operations.

Powering the SAC12000 are two high-performance engines:

Upper Engine: 290 kW at 1800 rpm, powering the superstructure for lifting operations.
Lower Engine: 480 kW at 1800 rpm, ensuring strong road mobility and climbing power.
With a minimum ground clearance of 281 mm, the crane can navigate rough terrain with ease. The maximum climbing capability of 36% allows it to tackle steep inclines, making it suitable for challenging job sites. The imported gearbox, transfer case, and axles ensure efficient power transmission, while a dual-circuit pneumatic braking system with multiple auxiliary braking methods enhances safety during transport and operation.

The SAC12000’s boom and counterweight system are designed for quick self-assembly and disassembly, improving job site efficiency. The main boom uses imported high-strength steel plates, featuring a fully automatic single-cylinder pinning system with mechanical, electrical, and hydraulic safety interlocks for maximum reliability.

The hydraulic system utilizes a proprietary dual-pump converging main valve, allowing for multi-stage pressure selection, optimizing energy efficiency across various load conditions. The closed-loop winch system provides high efficiency with minimal energy loss, offering fine micro-movement control and stepless speed adjustments, ensuring smooth and stable lifting.

With its exceptional lifting performance, advanced safety features, and high-tech hydraulic systems, the Sany SAC12000 is a flagship model for Sany, showcasing China’s engineering innovation in the global heavy lifting market. Its dominance in wind turbine installation and large-scale infrastructure projects reinforces its status as a powerful alternative to European-manufactured cranes in the 1,200-ton class.
