Cat SEM520 soil 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

· 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 ℃

· 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

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
