SEM522 Soil Compactor Roller

• 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

  •  SEM522 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

  • 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
