P305KHSIV pneumatic-tired roller is a large tonnage tired roller produced in light of market requirements. This product uses pneumatic tires as working device to compact the paving materials. It is mainly suitable for compacting operations of asphalt pavement, base layer, sub-base layer, dams and filling projects, etc., and is an ideal compaction equipment for construction of high-grade highways, airports, harbors, embankments and industrial construction sites. 

Advantages: 

1. The after-treatment system is composed of EGR, DOC and DPF, which only requires oil and does not need urea to reduce user’s use cost; it has very high work reliability, fuel economy, low noise and low emission. 

2. The drive system is composed of hydraulic driving pump, driving motor, driving axle, chain and rear wheel. The closed hydraulic driving system consisting of imported variable pump and variable motor is adopted to ensure good driving performance and high climbing ability of roller. The two-gear infinitely variable transmission ensures that the operation is carried out at the most suitable speed under different conditions. Soft start and stop of machine can be implemented to ensure good operating comfort. 

3. The dual-loop all-wheel braking technology is adopted to enable higher braking efficiency, high response speed, short braking distance and higher reliability. The complete machine is safe, and particularly suitable for operations in mountainous conditions.
