Sany STC1200S truck crane is the first 120t-class crane of 5 axles and 7-section boom in China, with 54.5t overall weight.

Innovative chassis system

The use of innovative 5-axle chassis design and multi braking modes provide more reliable traveling performance for chassis.

With tipping early-warning technology, high stable overall operation and high safety can be achieved.

Safe and stable lifting performance

Seven-section boom of high strength steel structure and optimized U-shaped section reduces weight significantly and improve safety rates.

Jib mounting angles are 0°, 15° and 30° which ensures fast and convenient change-over between different operating conditions so as to improving working efficiency of the machine.

Unique hydraulic control technology

Self-developed dual-pump converging / diversion main valve is used. Converging flow of the single-action dual-pump ensures fast operation and high work efficiency; combined-action dual pump diversion system is applied to ensure stable controllability.

Electric proportional variable displacement piston pump is used to ensure high-accurate flow control and higher efficiency and energy saving.

Intelligent electronic control

Self-developed controller SYMC specially made for engineering machinery is adopted. The adoption of CAN-bus full-digital network control technology ensures stable control signal, simple harness and high reliability. Timely feedback of data information can achieve the monitoring of the overall working status in real time.

The load moment limiter equipped with the comprehensive intelligent protection system is used with accuracy within 5% to provide a comprehensive logic and interlock control, thus ensuring more safe and reliable operation.

Comfortable

385/95R25 tyre is equipped which is excellent in ability of cross-country with better stability. Sleeper is equipped in the driving cab providing comfortable condition for the driver.
