Product Description

Reliable Quality SEM520 Road Roller 20ton Single Drum Vibratory Road Compactor Roller 
 

Product Description

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 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

SEM520 utilize imported piston pump and motor
