Product Description

Chinese Best Quality 20 Ton 130KW SEM520 Single Drum Road Roller

Key Specification
* Std Rated Power-Gross : 129kW
* Rated Speed : 2,000r/min
* Turning Radius Inside Drum Edge : 6,350mm

Advantage
* High Efficiency: The unique vibratory pod design along with 50 mm thick drum provides superior compaction performance
* Reliability: Vibration system utilizes eccentric vibe pod design, extends life over 50%
* Operation: Digital frequency meter and three level alarm system monitor machine performance

Features
Vibe Pod Design
* Eccentric vibe pod design, extends system life by 50%
* Steel shot moving inside closed eccentric block, stable and reliable vibe amplitude, reduces impact to motor, prolongs maintenance period of vibratory system
* Completely sealed eccentric gear eliminates contamination, prolongs bearing life

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

Vibratory Hydraulic System
* Closed center hydraulic system
* Improves efficiency by 20% over the open center system 
* Reduces oil contamination, prolongs life of hydraulic system
* Maintains higher pressure and smaller energy loss
* Allows for simpler hose routing
* Requires smaller volume hydraulic tank, reduces maintenance cost
* World class vibratory hydraulic components
* SEM518 utilize Sauer piston pump and motor
* Vibratory hose
* Utilize Eton hoses and joints, high reliability
* Optimized hose routing, prolongs hose life

Powertrain
* Electronically controlled transmission
* 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
