Model Number: QY80v
Key Specifications/Special Features:
Our products:1) All kinds of China construction machinery:(Types: wheel loader, excavator, cranes, paver, road roller and tractor)2) All kinds of trucks(Types: dump truck, tractor truck, concrete mixer truck, cargo truck and trailer)Excellent and stable chassis performance/chassis system:STC750 crane utilizes a double-axle drive that provides good traffic ability and comfort under complex road condition with reliable performance, engine has a multimode power output function which reduces power consumption, use of tipping over early-warning technology helps keep you safe on the jobUltra-long and super strong boom system with highly sensitive load lifting capacity:
Features a five-section boom made from high strength steel and optimized U-shaped section which reduces weight and significantly improve safety, jib mounting angles are 0°, 15°and 30° which ensures quick change-over between different operating conditions so as to improve working efficiency of the machine
Highly efficient, stable, energy-saving and adjustable hydraulic system:
Load feedback of hydraulic system and constant power control provide powerful lifting capacity and excellent micro-mobility, unique steering buffer guarantees smooth braking
Safe, stable, advanced, and intelligent electric control system:
Uses a self-developed controller SYMC specially designed for engineering machinery, application of CANbus fully digital network control technology ensures stable control signal, simple harness, and high reliability, it can provide feedback on data and monitor the working condition of whole crane in real-time, load moment limiter is configured with comprehensive intelligent protection system that achieves precision within 5%, by using a comprehensive logic and interlock control system, the STC750 ensures safe and reliable operation
