China Construction Machinery 8ton Truck Crane STC80 for Sale
STC80 truck crane has the largest lifting moment, main boom length, lifting height, and outrigger span in the same tonnage product in the industry, with a maximum lifting moment of 318NM; U-shaped main boom, boom length 25.6m, lifting height 25.5 m; the outrigger span is 4.9m×4.39m.
1.Double-axle drive is used, providing good traffic ability and comfortableness under complex road condition with reliable traveling performance.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.
2.Electrical proportion Hydraulic system load feedback, piston pump, electrical controlled valve and constant power control are applied to provide strong lifting capacity and good micro-mobility.Unique steering buffer design is adopted to ensure stable braking operation.
3.Five-section boom of high strength steel structure and optimized U-shaped cross reduces weight significantly with higher 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.
4.Self-developed controller SYMC specially for engineering machinery is configured.
The adoption of CAN-bus full-digital network control technology ensures stable control signal, simple harness and high reliability.
5.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 3% to provide a comprehensive logic and interlock control, thus ensuring more safe and reliable operation.
