Product Description
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 systemSuction style fan pulls low temperature air through the r
- adiator, 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
