Double-axle drive is used, providing good trafficability 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.
Highly efficient, stable, energy-saving and
adjustable hydraulic system
Hydraulic system load feedback and constant power control
is applied to provide strong lifting capacity and good micromobility. Unique steering buffer design is adopted to ensure
stable braking operation.
Super-strong, super-long and sensitive
lifting capacity
Five-section boom of high strength steel structure and optimized
U-shaped section 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.
Safe, stable, advanced and intelligent
electric control system
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. Timely feedback of data information
can achieve the monitoring of the overall working status in realtime. The load moment limiter equipped with the comprehensive
