Product Description

Features

Vibe Pod Design

• Eccentric vibe pod design extends system life by 50%
•  Steel shot moving inside a closed eccentric block, stable and reliable vibe amplitude, reduces impact to the motor, prolongs maintenance period of the 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

Cooling System

• The isolated modular cooling system
• Suction style fan pulls low-temperature air through the radiator, providing the superior cooling capability
• The optional high ambient cooling system allows the machine to work in ambient temperature up to 50 ºC
• The Shunt tank provides constant system pressure and provides an easy visual check of the coolant level

Vibratory Hydraulic System

• Closed center hydraulic system
• Improves efficiency by 20% over the open center system
• Reduces oil contamination, prolongs the life of the 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 a Sauer piston pump and motor
• Vibratory hose
• Utilize Eton hoses and joints, high reliability
• Optimized hose routing, prolongs hose life

Key Features

• Application/Versatility
• Applications include road, railway, airfield, and industry yard compaction
• Optional diamond shape pad-foot roller for compacting clay soils
• Optional square shape pad-foot roller for compacting sandy materials
• High efficiency
• 50mm drum, compaction performance is 10%~15% better than competitors
• Isolated modular cooling system, works in the ambient temperature of 43 ºC
• Reliability
• The vibration system utilizes an eccentric vibe pod design, extends life up to 50%
• Closed center hydraulic system, world-famous piston pump, and motor
• Electronically controlled transmission, easy and
• comfortable to operate
• Operation
• Digital frequency meter monitors compaction frequency
• Three-level alarm system and Engine speed gauge monitor machine performance
