Sem 20ton Singel Drum Vibratory Road Roller Sem520

product description

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

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.

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

• SEM518/520 utilize Sauer piston pump and motor
• SEM522 utilize Rexroth piston pump and motor

Vibratory hose

• Utilize Eton hoses and joints, high reliability
• Optimized hose routing, prolongs hose life
