Sany SCC8000A

Debuting as one of Sany’s flagship high-capacity crawler cranes, the SCC8000A is designed for challenging lifting scenarios, including wind turbine erection, petrochemical installations, and large-scale construction. With a maximum rated lifting capacity of 800 tons at a 12-meter operating radius (using superlift), the SCC8000A combines brute strength with advanced engineering precision. Its standard lifting capacity is 650 tons at a 7-meter radius without superlift. The crane achieves a maximum lifting moment of 12,000 t·m in its most capable configuration.

The crane supports a variety of boom configurations. Its main boom spans from 24 to 111 meters with superlift, while the luffing jib extends from 24 to 96 meters. There are hybrid configurations that can extend the working range to a massive 168+12 meters in wind energy applications. The fixed jib offers lengths from 12 to 15 meters for additional versatility. The boom system is constructed with high-strength lattice sections using rolled and welded steel pipes, ensuring structural integrity under heavy loads.

On the superstructure, the crane is powered by a Cummins engine rated at 447 kW at 1800 rpm, complying with Euro Tier III or optionally Tier IV emissions standards. The hydraulic systems are all closed-loop for efficiency and durability, and the main hoist winches provide a rope speed of up to 164 m/min. The slewing mechanism enables smooth 360° rotation with a top speed of 0.8 rpm.

The undercarriage features independently driven crawler assemblies, each with two-speed ranges for better maneuverability. Travel speed is limited to 1.0 km/h in high gear, appropriate for the crane’s massive weight and size. The gradeability is 15% with the base boom, and ground pressure is kept to a relatively low 0.2 MPa due to the wide crawler base.

The SCC8000A weighs approximately 610 tons in its working configuration, including a 24-meter base boom, 230-ton machine counterweight, 90-ton carbody counterweight, and the 800-ton hook. The crane incorporates a 390-ton superlift counterweight when needed. Counterweights are modular and self-assembling, improving efficiency during site setup.

Operator comfort and safety are top priorities, featuring a Porsche-designed cab with excellent visibility, climate control, and an ergonomic layout. Safety systems include a proprietary load moment limiter, over-hoist and over-release protections, slew and travel alarms, real-time monitoring systems, and remote diagnostics.

Overall, the Sany SCC8000A embodies heavy-duty lifting performance blended with sophisticated control and modular adaptability, marking it as a top-tier solution in the global crawler crane market.
