Product Description
Top brand Hydraulic System 20 Ton Road Roller with Single Drum SEM520
Isolated modular cooling system
![Road Construction Machinery 20ton Road Roller 520 7]()
* 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 ℃ Shunt tank provides constant
system pressure and provides easy visual check of coolant level
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.
* SEM520/522 are equipped with a 50 mm thick drum compared to competitors with a 40 mm thick drum, provides increased compaction
performance versus the competition.
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
* SEM518/520 utilize Sauer piston pump and motor
* SEM522 utilize Rexroth piston pump and motor
Vibratory hose
* Utilize Eton hoses and joints, high reliability
* Optimized hose routing, prolongs hose life
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
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
Application/Versatility
* Applications include road, railway, airfield and industry yard compaction
* Optional diamond shape pad-foot roller for compacting clay soils
* Optional square shape pad-foot roller for compacting sandy materials
High efficiency
* 50mm drum, compaction performance is 10%~15% better than competitors
* Isolated modular cooling system, works in ambient temperature of 43 ℃
Reliability
* Vibration system utilizes an eccentric vibe pod design, extends life up to 50%
* Closed center hydraulic system, world famous piston pump and motor
* Electronically controlled transmission, easy and comfortable to operate
Operation
* Digital frequency meter, monitors compaction frequency
* Three level alarm system and Engine speed guage monitor machine performance
Tiltable Cab
It offers a tiltable cabin which provides more convenient maintenance of the pump, transmission, hose and electronic components
