CVRP451L 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.
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.
There is reverse blade in the middle of the material distribution
bin, which can effectively improve the material supplying from the
lower part of the bin and prevent dissociation.
Efficient control system
It adopts mechanical-electric-hydraulic integrated control
technology, featuring high level of automation, control accuracy
and reliability.
The left/right feed/material distribution device adopts ultrasonic
level gauge which can achieve automatic even feeding of materials.
The standard configuration includes electronic automatic leveling
device which ensures higher evenness of the paving surface.
Strong power system
Anhui Shangchai 4JR3G1 diesel engine, 55KW, large power reserve.
The combined radiator effectively reduces the working temperature
of the engine and hydraulic system and ensures long-time reliable
work.
Advanced screed technology
Hydraulic stepless extension/withdrawal, applicable to the work
condition of widened road.
The unique frame design, and good overall rigidness of the screed.
The stepless adjustable vibration frequency can meet the
requirements for various work conditions.
The quick gas heating design, nozzle with safety switch, and the
heating is quick and safe.
Performance advantages
Compact structure, flexible control.
The minimum width of the machine body is 2m, which can be used
freely at narrow roads.
The hopper is folded from single side, and the pushing wheel can be
folded with the hopper synchronically, which improves the pass
ability of the machine.
The control panel features centralized control, simple and
convenient operation; combined instrument, and the work condition
is very clear.
Excellent performance, wide application
Quick site transfer and paving speed, applicable to the
construction of municipal highway and country road as well as the
maintenance operation of expressway and various kinds of highways.
With small minimum paving width, it is applicable to the
construction work of streets for residential areas and scenic
spots.
Equipped with hydraulic telescopic screed, it is applicable to the
paving of widened roads.
It adopts rear 4WD, which has large ground adhesive force,
applicable to the paving of various kinds of road surface.
The wide hopper is applicable to various kinds of dump vehicle, the
storage capacity of the hopper is up to 12t, which ensures
successive paving operation.
