Stable Quality 20 TON 520 Road Roller with SPARE PARTS
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
520 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
520 utilize imported piston pump and motor
