Product Description



SEM522 vibratory types of road roller low price road roller compactor

 

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  
 

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 gauge monitor machine performance
 

 

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

·SEM520/522 are equipped with a 50 mm thick drum compared to competitors with a 40 mm thick drum, provides increased compaction performance versus the competition

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 ℃

·Shunt tank provides constant system pressure and provides easy visual check of coolant level
 

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

·SEM522 utilize Rexroth piston pump and motor

 

Vibratory hose

·Utilize Eton hoses and joints,  high reliability

·Optimized hose routing, prolongs hose life
 

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 has higher travel speed
 

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
