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
