Company Profile

Product Description

China Brand New Sem Single Drum Roller Sem520 Roller in Stock

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 ℃
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

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

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 ℃
 

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
