Power system
Cumns QSB4.5 engine featuring high power output, reliable performance, economical and fuel consumption. It adjusts itself to idle speed in non-working status so as to save fuel. The temperature-control fan and load sensing system reduces fuel cost.

Vibration system 

Vibration system of SR14D-3 roller has two frequencies, 51Hz and 67Hz. Operation efficiency is 34% improved. In addition, the small amplitude of 0.3mm is applicable to compaction of thin layer and pavement of bridge while the large amplitude of 0.8mm is applicable to compaction of thick layer. Compaction efficiency is improved.
The electric hydraulic control system is composed of imported elements with advanced design and control technologies to ensure proper time of starting vibrating and stop vibrating and even compaction.
Spray system
The 110L large water tank prolongs operation time. The tank is provided with two filling holes and two drain holes.
Cab
Wide and bright cab provides comfortable driving and broad view of sight.
The operation panel can slide to turn for 180° to meet operator’s requirement.
High solution display clearly shows water level, oil level, water temperature, oil temperature and frequency, ensuring easy operation.
View of sight
SR14D-3 provides broad view of sight and comfortable driving for operator.
High operation quality 
Consistent amplitude of drums and staggered layout of vibration side and driving side ensure even compaction.
Gentle start and stop avoids soil from clustering the machine;
Operation speed and impact frequency can be set via the speed knob so as to ensure each operation with same frequency and improve the compaction.
Service and maintenance
The engine hood is designed like two wings of bird: when the two wings are open, hydraulic pump is seen and accessible; maintenance and service locations are accessible when standing on ground; the hydraulic oil tank is 40L only, saving cost for users; the spray system is under the engine; it is easy to wash the nozzle and filter and drain off the water in cold winter.
