12 Ton Road Roller SEM512
Vibration system
* Pod-type vibration system provides better performance and reliability
* The movable steel ball is enclosed inside the eccentric wheel, and the position of the center of gravity is adjusted through the direction of rotation to achieve the purpose of adjusting the amplitude.
* Stable vibration, smooth amplitude switching, reducing the impact on the vibration motor and prolonging the lifespan
* Fully sealed eccentric wheel, no pollution, prolong bearing life. Maintenance-free within 2 years/2000 hours, reducing
maintenance costs
Cooling system
* Suction fan, fresh low-temperature air enters from the rear of the whole machine and passes through the radiator to the engine to ensure the heat dissipation effect
* Optional high temperature cooling system, can work under 50 degrees of ambient temperature
Hydraulic system
* Closed hydraulic circuit, hydraulic transmission efficiency is 20% higher than that of open circuit
* The pumps and motors of world-renowned brands form a closed circulation system to reduce oil
* Probability of contamination, higher system cleanliness, prolonging the service life of the hydraulic system
* The vibration system has higher pressure and less energy loss
* The pipeline layout is simpler, increasing the maintenance space
* Only need to be equipped with a smaller volume hydraulic oil tank, reducing maintenance costs
* The pressure measuring joints are all designed to the vibration pump, which improves the service life of the pressure measuring joints
Electronically controlled engine
* SEM518/520 uses WP6G175E301 (129kW), SEM522 uses WP6G190E301 (140kW)
* Emissions meet the national three standards Dash board
* The three-level fault alarm system can accurately judge the severity of the fault at the fault point according to the alarm
level
* During use, real-time detection of abnormal conditions of multiple systems to prevent failures
* Vibration frequency meter displays the compaction frequency in real time, monitors the compaction effect and possible frequency drop phenomenon; through the frequency change, timely judge the possible failure of the hydraulic system Cab
* Manually flip the cab as standard
* Optional hydraulic tilting cab
* Rearrange the panel to make the operation switch more user-friendly
* Knob type electronic throttle, flexible and more reliable
