China Top Brand Single Drum Vibrating 22Ton Road Roller SEM522 with Dual Drive
Advantages of SEM522:
* High Efficiency: The unique vibratory pod design along with 50 mm thick drum provides superior compaction performance
* Reliability: Vibration system utilizes eccentric vibe pod design, extends life over 50%
* Operation: Digital frequency meter and three level alarm system monitor machine performance
Remarkable 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
-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 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
-SEM522 utilize Rexroth piston pump and motor
-Utilize Eton hoses and joints, high reliability
-Optimized hose routing, prolongs hose life
Powertrain
-Electronically controlled transmission
-Easier to shift, reduces operator fatigue and improves working efficiency
-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
Tiltable Cab
Offers a tiltable cabin which provides more convenient maintenance of the pump, transmission, hose and electronic components
Hydraulic tiltable cab is optional
