Road Roller Made in China SEM522 for Sale
Technical Features
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
- SEM520/522 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 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™
