Vantaggi e funzioni

Excellent traveling capacity and high performance chassis system

Four-wheel drive is applied with four steering modes to provide good mobility. Trafficability and comfortableness of the complex road condition is improved thanks to its Min. turning radius of no more than 6.7m.

Ultra long and super strong boom system

Four-section boom of high strength steel structure and optimized U-shaped section, reducing weight and improving safety significantly. Jib mounting angles are 0°, 15°, and 30° which ensure fast and convenient change-over between different operating conditions so as to improve working efficiency of the machine.

Highly efficient and unique 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 guarantees smooth braking operation.

Safe and reliable control system

Self-developed controller SYMC specially for engineering machinery is configured. The application of CAN-bus fully digital network control technology ensures stable control signal, simple harness and high reliability. It can feedback the data information and monitor the working condition of whole crane in real-time. Load moment limiter configured with comprehensive intelligent protection system is adopted with precision within 10%.The adoption of comprehensive logic and interlock control system ensures more safe and reliable operation.
