SANY STC550H Mobile Crane
Product Feature
Stable chassis performance
Double-axle drive is used, providing reliable traveling performance under complex road conditions.
Engine has the multimode power output function, which reduces power consumption.
The use of tipping over early-warning technology provides high stability and safety of the overall operation.
Energy-saving hydraulic system
Hydraulic system load feedback and constant power control is applied to provide strong lifting capacity and good micro-mobility.
Unique steering buffer design is adopted to ensure stable braking operation.
Strong load lifting capacity
Five-section boom of high strength steel structure and optimized U-shaped cross section reduces weight significantly with higher safety rates.
Jib mounting angles are 0° 15°and 30°, which ensures fast and convenient change-over among different operating conditions so as to improve working efficiency of the machine.
Intelligent electric control system
Self-developed controller SYMC specially for engineering machinery is configured.
The 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.
Safety devices
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.
