The RP403 paver is the first full-hydraulic small crawler asphalt paver in China. The whole machine adopts full hydraulic drive and electro-hydraulic automatic control, advanced technology and reliable performance.
The minimum width of the whole machine is only 1.8 meter, which is the smallest among domestic products. Due to its compact shape, it is widely used in large scale paving, including sidewalks, bike lanes, farm roads and small roads.
The paving width can be stepless adjusted from 0.8 meters (if installed with width limit device) to 4.5 meters, and is especially suitable for the maintenance of roads.

* The machine is miniaturized, and the super small width of 1.8m fufills the construction work of the urban area and the roadway; Install the limited-width device, the minimum paving width of 0.8m, to be applied to the paving construction of “grooves”.

* Configured with Deutz water-cooled turbocharged diesel engine, sufficient power reserve, good atomization of diesel, good economic performance, low noise, long life and wide application scope.

* The powerful three phase alternator generator with management system, controls the power output of the corresponding paving width, can heat the screed to the working temperature in a very short time.

* The hydraulic system adopts the load sensing control technology to make the power output efficient and energy saving. The drive element is imported German Rexroth, which guarantees the system reliability.
