SEM Hydraulic Drive Single Drum Road Roller SEM512
Features:
SEM 512 road roller--from Caterpillar, worth your trust
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
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 ºC
- 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
- SEM518 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 ºC
- 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
- SEM offers a tiltable cabin which provides more convenient maintenance of the pump, transmission, hose and electronic components
- Hydraulic tiltable cab is optional
