Product Description

SEM Road Roller (SEM522)

Advantages

* High Efficiency: The unique vibratory pod design along with 50 mm thick drum provides superior compaction performance

* Reliability: Vibration system utilizes eccentric vibe pod design, extends life over 50%

* Operation: Digital frequency meter and three level alarm system monitor machine performance

 

Features

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
• Vibratory hose
• Utilize Eton hoses and joints, high reliability
• Optimized hose routing, prolongs hose life

Cat ® Product Link™

• Cat ® Product Link™ will support your business, and accurately convey information of the equipment to relevant personnel in a timely and effective manner for your better equipment management.

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
