三一重工 STC800T6

The SANY STC800T6 is an 80-ton class all-terrain truck crane designed for high-altitude, long-distance, and heavy-lift construction scenarios. It features a 6-section ultra-long main boom and a professional counterweight configuration, making it one of the core models in SANY's medium-to-large crane product line. Core Technical Parameters 表格 Parameter Specification Max. Rated Lifting Capacity 80 tons (at minimum radius with base boom) Gross Vehicle Weight 50,000 kg (50 tons, compliant with road transport regulations) Main Boom 6-section U-shaped high-strength steel boom - Min. Length 12.65 m (basic boom) - Max. Length 57.6 m (fully extended) Auxiliary Boom 27 m truss-type auxiliary boom Max. Lifting Height 58 m (main boom alone); 84.6 m (main + auxiliary boom) Max. Counterweight 20 tons (modular design, removable) Max. Lifting Moment Approx. 3,352 kN·m Outrigger Span 8 m (transverse) × 6.43 m (longitudinal) Travel Speed Max. 92 km/h Minimum Turning Radius 12 m Key Features 6-Section Ultra-Long Main Boom The 57.6 m fully extended main boom adopts an ultra-wide U-shaped section design. It significantly improves lifting height and range, easily meeting the hoisting needs of high-rise buildings, wind power towers, and bridge projects. The single-cylinder pin telescopic technology ensures smooth and efficient boom extension/retraction. Modular Counterweight System Equipped with a 20-ton modular counterweight, it can be disassembled and assembled as needed. During low-speed transfer, it can be equipped with 12 tons of counterweight to meet road transport requirements; during heavy lifting operations, the full counterweight ensures excellent 整机 stability. High-Efficiency Power & Mobility Powered by a high-power diesel engine (e.g., Weichai WP12 series, 276 kW/375 hp), it provides strong power for both chassis driving and upper hydraulic system operation. The 10-speed transmission and 5-axle chassis enable fast transfer between construction sites, with a maximum speed of 92 km/h, greatly improving operation efficiency. Safe & Reliable Operation Equipped with a full-range outrigger, multi-stage safety protection devices, and real-time load monitoring system, it effectively prevents overturning and overload risks. The human-computer interaction interface is user-friendly, facilitating precise operation and daily maintenance. Typical Applications High-Rise Construction: Lifting steel structures, precast components, and large equipment for skyscrapers. Wind Energy Engineering: Hoisting wind turbine components and tower sections. Infrastructure Projects: Bridge girder erection, tunnel equipment installation, and heavy machinery replacement. Specialized Hoisting: High-altitude line maintenance, tower crane installation/dismantling, etc.
