Product Description

 

Product Description

High efficiency and low consumption

Engine can precisely controls the fuel jet according to the various working modes, to make the fuel burn more sufficiently.

Excellent reliability and durability

The self-independently DOMCS dynamic optimized intelligent control system realizes the perfect match of the engine and the main pump, making the movement more fast and also prolonging the service life.

Users friendly design
The brand-new damping system, cab with extra-large view, strengthened noise reduction design, greatly improve the operation experience.

 

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
* SEM520/522 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
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 leve

 

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
* SEM518/520 utilize Sauer piston pump and motor
* SEM522 utilize Rexroth 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 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
