SEM520 Soil Compactor Roller

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 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 ℃

• 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 Sauer piston pump and motor

• Vibratory hose

• Utilize Eton hoses and joints, high reliability

• Optimized hose routing, prolongs hose life

Cat ® Product Link™
