새니 STC 800 T5

The SANY STC800T6 is an 80-ton class six-section boom truck crane, featuring an ultra-long main boom and high mobility. As a core model for medium-to-large construction lifting, it is widely used in high-rise buildings, wind power, bridge engineering, and other scenarios. 2. Core Technical Parameters 表格 Item Specification Max. Rated Lifting Capacity 80 tons (at minimum radius with base boom) Gross Vehicle Weight 46 / 50 tons (early / standard version) Main Boom 6-section U-shaped high-strength steel boom - Min. Length 12.65 m - Max. Length 57.6 m Auxiliary Boom 27 m truss-type auxiliary boom Max. Lifting Height 58 m (main boom only); 85 m (main + auxiliary boom) Max. Counterweight 20 tons (modular, removable) Outrigger Span 8 m (transverse) × 6.43 m (longitudinal) Max. Travel Speed 92 km/h Min. Turning Radius 12 m 3. Key Advantages 1. Ultra-Long Main Boom Design The 57.6 m six-section main boom leads in length among cranes of the same tonnage, covering more high-altitude and long-radius operations. Single-cylinder pin telescopic technology ensures smooth extension/retraction and precise positioning, improving work efficiency. 2. Flexible Counterweight & Stability 20-ton modular counterweight can be adjusted according to working conditions, balancing heavy-lift stability and transfer convenience. Full-extended outriggers with large span provide strong anti-overturning capability, adapting to complex construction site terrain. 3. Efficient Power & Control Chassis is powered by Weichai WP12 series engine (375–400 hp), delivering strong power for climbing and site transfer. Independent upper-structure engine (Cummins QSB6.7 or Weichai WP6G) provides stable power for the hydraulic system, ensuring smooth and powerful lifting, luffing, and slewing actions. Electro-hydraulic proportional control with intelligent flow distribution enables precise operation and smooth compound movements. 4. Safety & Reliability Equipped with multiple safety devices such as moment limiter, overload protection, and outrigger lock, effectively preventing overturning and overload risks. High-strength boom structure and mature hydraulic system ensure high reliability and low maintenance costs. 4. Typical Applications High-rise construction: Lifting steel structures and precast components Wind energy engineering: Installing wind turbine towers and nacelles Bridge construction: Erecting bridge girders and installing equipment Industrial equipment handling: Positioning large machine tools and pressure vessels Special scenarios: High-altitude line maintenance and tower crane assembly/disassembly 5. Version Differences Early version: Gross weight 46 tons, lightweight design, more suitable for short-distance transfer. Later standard version: Gross weight 50 tons, reinforced structure, further improved lifting performance and stability.
