RP756 is a kind of new generation multifunctional paver. It is completely upgraded with new technology, featuring excellent performance, simple operation, and superior performance/price ratio. With the max. paving width of 7.5m, it is the optimal equipment for paving various kinds of materials for the construction of highways. The conveying system and material distribution system have extra large capacity and they are independently driven (from left/right), which can meet different construction requirements. In addition, it is more to operate and it can achieve optimal paving effect under the most tough work environment.
Technical Features
Power Drive Technology: Efficient And Powerful
It is equipped with D6114 diesel engine which is water cooling and
turbocharged, applicable to operations at plateau areas.
The cooling system
adopts extra-large radiator, which ensures good heat dissipation even at high
temperature environment.
Material Feeding or Distribution Technology:
Reliable And Durable
High capability of material distribution, large
spiral pitch 360mmΦ420 large diameter distribution blade, 28BH reinforced drive
chain, and the drive ability is 25% larger than similar products.
The
material distribution box and chain all adopt high strength design, high
transmitted power, and the max. transmitted capability of the distribution shaft
is 5000Nm. It can achieve all buried material distribution, which can greatly
reduce the segregation.
It adopts 2 reverse blades at the middle of the
distribution bin, which can effectively eliminates the segregation belt in the
middle.
Control Technology: Stable And Accurate
The drive system adopts
left/right independent drive, microcomputer control technology and constant
speed automatic control technology, featuring good straight travel capability,
which ensures stable speed and that the paving speed will not be affected by the
load.
The material level control adopts supersonic sensing technology, in
addition to electro-hydraulic controlled conveying speed, which ensures
automatic control of the height of mixed materials in front of the
screed.
The material distribution system adopt 2 sets of independent closed
hydraulic circuit, featuring independent control and 2-stage proportional speed
regulation.
The automatic electronic leveling ensures high flatness; multiple
sensing mode are available, high automation level, orifice plate and constant
pressure technology… all these ensures the stability of leveling cylinder speed.
Screed Technology: Mature And Reliable
The most mature and
reliable double vibrator gas heating screed.
Stepless adjustable double
vibrator frequency, applicable to various paving conditions.
The screed
lifting cylinder has floatation and lock up function, applicable to various
paving materials and work conditions.
It can be equipped with eccentric
vibration device.
Performance Advantages
Excellent Configuration
The powerful heat
dissipation system, supersonic material level control, automatic leveler,
imported microcomputer control, travel reducer, hydraulic pump and key
components, centralized lubrication system, wear resistant steel plate and
bearing, etc.
The bottom plate and protection device all adopt Germany
imported extra wear resistant steel plate which is improved by 3 times in the
wear resistance and greatly improves the life of bottom plate.
The
centralized forced heat dissipation has good effect; the specially designed
extra-large combined radiator can work normally when the ambient temperature is
50℃.
Convenient Maintenance
The originally imported centralized
automatic lubrication system greatly reduces the maintenance work and prolongs
the life of bearings at the high temperature part, which improves work
efficiency and saves maintenance time.
The crawler undercarriage made up of
maintenance-free supporting wheel and rubber track plate does not damage the
road and it is durable.
The triune travel drive device and side cover is
convenient for maintenance.
Convenient Operation
The centralized control has user friendly
interface, and it is simple and reliable to operate. All the control elements
are installed on the mobile instrument case. The seat can be extended outside of
the cab, and there are two seats, which is comfortable and convenient to
operate.
The left/right material distribution device can move up and down
quickly at the same time, which adapts to different paving thickness and the
site transfer is quick and convenient.
