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 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

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
