Product Description
20ton Vibratory Road Roller Soil Compactor SEM520 Hot Sale
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
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
- SEM518/520 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
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
Key Features
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 ºC
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
