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 ℃ 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
Cat ® Product Link™
Cat ® Product Link™ will support your business, and accurately convey information of the equipment to relevant personnel in a timely and effective manner for your better equipment management.
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
Dashboard
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
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 ℃ 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 Hydraulic tiltable cab is optional
