1. 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 is equipped with a 50 mm thick drum compared to competitors with a 40 mm thick drum, provides increased compaction performance versus the competition
2. Vibratory Hydraulic System
2.1. 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
2.2. World class vibratory hydraulic components
◊ SEM520 utilize Sauer piston pump and motor
2.3. Vibratory hose
◊ Utilize Eton hoses and joints, high reliability
◊ Optimized hose routing, prolongs hose life
3. Powertrain
3.1. Electronically controlled transmission
◊ Easier to shift, reduces operator fatigue and improves working efficiency
◊ High reliability
3.2. 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
4. Key Features
4.1. 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
4.2. High efficiency
◊ 50mm drum, compaction performance is 10%~15% better than competitors
◊ Isolated modular cooling system, works in ambient temperature of 43 ºC
4.3. 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
4.4. Operation
◊ Digital frequency meter, monitors compaction frequency
◊ Three level alarm system and Engine speed guage monitor machine performance
