China top brand SEM520 20tons single drum road roller for sale1. Product Features
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 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
SEM520 utilize imported piston pump and motor
Vibratory hose
Utilize imported 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
Tiltable Cab
SEM offers a tiltable cabin which provides more convenient maintenance of the pump, transmission, hose and electronic components
The hydraulic tiltable cab is optional
