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 °C

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.
• SM520/522 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

• SM518/520 utilize Sauer piston pump and motor
• SM522 utilize Rexroth piston pump and motor

Vibratory hose

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