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

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
• SEM518 utilize Sauer piston pump and motor
• Vibratory hose
• Utilize Eton hoses and joints, high reliability
• Optimized hose routing, prolongs hose life

Cat ® Product Link™
