SEM522 Road Rollers

-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

-SEM522 road roller are equipped with a 50 mm thick drum compared to competitors with a 40 mm thick drum, provides SEM522 road roller increased compaction performance versus the competition

-Isolated modular cooling system

-Suction style fan pulls low temperature air through the radiator, providing SEM522 road roller superior cooling capability

-Optional high ambient cooling system allows SEM522 road roller to work in ambient temperature up to 50 ℃

-Shunt tank provides SEM522 road roller constant system pressure and provides easy visual check of coolant level

-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

-SEM522 road roller utilize Rexroth piston pump and motor

-Electronically controlled transmission

-Easier to shift, reduces operator fatigue and improves working efficiency

-Vibratory Frequency Meter

-Continuously displays road roller compaction frequency

-Operator may select appropriate frequency to avoid excessive compaction

-Mould formed cab with all trims design and more vents with HVAC make operator feel better

-First class premium seat with suspension adjustable, arm rest and safety belt. Up-down, forward and reverse adjustable

-Cat technology damping mount reduce vibration failure

-Slide window, fresh air inlet system make environment better

-SEM522 road roller offers a tiltable cabin which provides SEM520 road roller more convenient maintenance of the pump, transmission, hose and electronic components

-Hydraulic tiltable cab is optional
