Product Description

Product Description

New 20ton Vibratory Single Drum Road Roller SEM520 Road Compactor

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
