Product Description

 

22 Ton Single Drum Road Roller 522 Asphalt Compactor
-----------------------------------------------------------------------------------------------
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
* 520/522 are equipped with a 50 mm thick drum compared to competitors with a 40 mm thick drum, provides increased compaction performance versus the competition

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
* 518/520 utilize Sauer piston pump and motor
* 522 utilize Rexroth piston pump and motor

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