Product Description

1. Energy saving and noise reduction: 8% less fuel consumption by using low speed transmission line; vibration reduction at engine, cabin and seat; multiple measures for low noise emis- sions of the whole machine.

 

2. Powerful and vigorous: Shangchai stage Ill variable power engine matched optimum torque converter, reducing the start time, maximizing torque output at low speed.

3. Swivel under load: improved pressure of hydraulic system, improved swivel force of the blade, high frequency quenching treatment of gear rings, enhancing the wear resistance and life span of the blade.

 

4. Efficient operation: increased hydraulic pump and hydraulic motor displacement, 20% higher oil cylinder speed, for unrivalled operation efficiency; optimized blade shape for fast and efficient work, optimal load distribution minimizes material accumulation within the rotary disc.

 

5. Safety and reliability:CAE optimized structural parts, reliable and durable; patented slewing bearing drive axle for long lifetime and higher reliability.
