China Sem Vibration Compactor Sem522 Steel Road Roller

Vibe Pod DesignEccentric 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 SystemIsolated modular cooling systemSuction style fan pulls low temperature air through the radiator, providing superior cooling capabilityOptional high ambient cooling system allows the machine to work in ambient temperature up to 50 ºCShunt tank provides constant system pressure and provides easy visual check of coolant level
Vibratory Hydraulic SystemClosed center hydraulic systemImproves efficiency by 20% over the open center systemReduces oil contamination, prolongs life of hydraulic systemMaintains higher pressure and smaller energy lossAllows for simpler hose routingRequires smaller volume hydraulic tank, reduces maintenance costWorld class vibratory hydraulic componentsSEM522 utilize Rexroth piston pump and motorVibratory hoseUtilize Eton hoses and joints, high reliabilityOptimized 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.
PowertrainElectronically controlled transmissionEasier to shift, reduces operator fatigue and improves working efficiencyHigh reliabilityAxle equipped with Proportional Torque differential (PTD)PTD controls torque applied to the wheels based on ground conditions, improves overall tractionGrade ability is 34% compared to competitors' at 30% Optimized transmission ratio, 1st gear has higher travel speed
DashboardVibratory Frequency MeterContinuously displays machine compaction frequencyOperator may select appropriate frequency to avoid excessive compactionThree Level Alarm SystemMachine will diagnose system issues and notify the operator with 3 levels of warning indicator lights and audio alarms
