SEM518

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

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

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.

Electronically controlled transmission
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

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

SEM offers a tiltable cabin which provides more convenient maintenance of the pump, transmission, hose and electronic components
Hydraulic tiltable cab is optional
