XCMG RP451L ASPHALT CONCRETE PAVER

As the smallest full-hydro-driving paver made in China.RP451L uti­lizes the techniques as follows: four-wheel driving, hydro-electric propor­tional infinite displacement, automatic-leveling system, automatic-con­trolled conveyors & augers. and gas-heated hydro-extendable screed with width range from 2.0m to 4.5m,etc.With the high performance-price ratio and super excellent agility,RP451L paver is the most perfect choice in various road construction, especially suitable for the urban zone, the city planning roadway and the netted county pavements.

Main Features:

As a miniaturized machine with 2.0m of the super narrow complete width and paving width, RP451L paver is satisfied to the requirement of urban zones and laneways.

Configured with Shanghai 4JR3G1 water-cooling diesel engine pow­ered 55kw, the paver can be used in the west high altitude area due to its wide-range adaptability in altiplano and its adequate power reserve. The four-wheel driving and full hydraulic infinite displacements ensure the machine operated automatically. simply and promptly. The each side of conveyors and augers can be separately controlled automatically via the mixture level sensors both on the right and left. The main switch of electric system realizes that only one switch point could operate all the functions of the whole machine including the auto leveling system. Therefore the operation is convenient and the smooth­ness can be improved efficiently.

The well-known imported hydro-electric units keep the paver''''''''''''''''''''''''''''''''s stability and convenient maintenance.

The hydraulic extensible screed has the advantage in the construction of the laneway with variation width in the city. its vibration frequency can be adjusted infinitely and its paving width ranges from 2.0m to 4.5m con­veniently

The automatic leveling system can accurately control the tolerance of longitudinal smoothness to 3mm/3m and the sensitivity of transverse slope to 2/10000 at the top of the criteria of highways. The paver can hold up hopper sides wholly or one side separately to improve the travel capability of the road in construction site.
