RP451L paver is the first full hydraulic compact type tyre asphalt concrete paver. It adopts full hydraulic drive and automatic electro-hydraulic control, featuring advanced technology and reliable performance. The minimum width of the machine is 2 meters, which is the smallest among homemade products. It is flexible and has wide applications. The rear 4WD technology effectively improves the driving force of the machine. The ergonomic design makes it simple and convenient to operate and maintain. Thus the product has high performance/price ratio.
RP451L paver can be widely used in the construction of highways, streets, country roads, expressways and the road maintenance work. It can effectively improve the flatness and compactness of the road surface.
Reliable drive system
It is the first set of full hydraulic drive compact type tyre asphalt concrete paver made in China. The travel, feed and material distribution system all adopt hydraulic drive, featuring good bearing capacity, high drive efficiency, and convenient control.
The plunger pump and motor all adopt products of America Sauer brand, and all the elements all adopt products of famous brands to ensure the reliability, such as control valve, steel pipe, joint, filter, etc.
Efficient feed/ material distribution system
The feed system and distribution system are independent and they can be controlled separately.
The single chain adopts unique double scraper blade, which effectively improves the conveying capability of the machine.
