Dashboard

Vibratory Frequency Meter

• Continuously displays machine compaction frequency
• Operator may select appropriate frequency to avoid excessive compaction

 

Three Level Alarm System

• Machine will diagnose system issues and notify the operator with 3 levels of warning indicator lights and audio alarms

Powertrain

Electronically controlled transmission

• Easier to shift, reduces operator fatigue and improves working efficiency
• High reliability

 

Axle equipped with Proportional Torque differential (PTD)

• PTD controls torque applied to the wheels based on ground conditions, improves overall traction
• Grade ability is 34% compared to competitors' at 30%
• Optimized transmission ratio, 1st gear has higher travel speed

Cooling System

Isolated modular cooling system

• Suction style fan pulls low temperature air through the radiator, providing superior cooling capability
• Optional high ambient cooling system allows the machine to work in ambient temperature up to 50 ºC

Shunt tank provides constant system pressure and provides easy visual check of coolant level
