• High Efficiency: The unique vibratory pod design along with 50 mm thick drum provides superior compaction performance
  • Reliability: Vibration system utilizes eccentric vibe pod design, extends life over 50%
  • Operation: Digital frequency meter and three level alarm system monitor machine performance

Vibe Pod

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 ℃ 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 Sauer 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
