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 or 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.
