Caterpillar SEM Vibratory Road Roller

Caterpillar SEM Vibratory Road Roller

Product Description(Road Roller)

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.

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

Cat^® Product Link^TM

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.
