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

SEM520 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

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

SEM520 utilize Sauer piston pump and motor

Vibratory hose

Utilize Eton hoses and joints, high reliability

Optimized hose routing, prolongs hose life

Powertrain

Electronically controlled transmission

Easier to shift, reduces operator fatigue and improves working efficiency

High reliability

Axle equipped with Proportional Torque differential (PTD)

PTD controls torque applied to the wheels based on ground conditions, improves overall traction

Grade ability is 34% compared to competitors' at 30%

 Optimized transmission ratio, 1st gear has higher travel speed

Dashboard

Vibratory Frequency Meter

Continuously displays machine compaction frequency

Operator may select appropriate frequency to avoid excessive compaction

Three Level Alarm System

Machine will diagnose system issues and notify the operator with 3 levels of warning indicator lights and audio alarms

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 ambient temperature of 43 ºC

Reliability

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 guage monitor machine performance

Tiltable Cab

SEM offers a tiltable cabin which provides more convenient maintenance of the pump, transmission, hose and electronic components

Hydraulic tiltable cab is optional
