Product Description

RP453L  4.5m Paving Width Concrete Asphalt Paver

Product Description

Technical features

Advanced and mature drive technology.
It adopts CZPT d mechanical-electrical-hydraulic technology, which represents the development trends of construction machinery industry.

Full hydraulic drive, electro-hydraulic proportional automatic constant control.

Unique, mature and reliable  drive axle technology.

Reliable and durable material ed/distribution technology

Full hydraulic drive and electric-hydraulic proportional automatic constant speed control.

High material distribution capability, Φ360 large diameter mixing blade, 28BH reinforced drive chain.

The material feed system and distribution system are independent; the supersonic material level CZPT ng control technology enables it to control the material height.

With high capability of anti-segregation, strong CZPT for material distribution, and high strength structure, it can achieve buried distribution and reduce segregation.

Stable and accurate control
It is equipped with electronic automatic leveling instrument, which can reduce the interference of human factors and effectively improve the levelness of road surface.
It adopts supersonic material level control technology, featuring high automation level, applicable to the construction requirements of CZPT kinds of road.

Screed technology
The most mature and stable hydraulic telescopic screed.

The large and rigid telescopic cylinder features high precision and good stability, which ensures excellent paving

The reasonable telescopic cylinder matches with the sleeve, which makes more accurate screed sliding.

The 3-point suspension system ensures stable extension/withdrawal of screed, in addition to stepless adjustable vibrating rotation speed, it can meet different work requirements.

Performance advantages

Excellent configuration
It adopts ZheJiang D4114 diesel engine, featuring low temperature start, energy-saving and environmental care, 
Powerful drive force

The travel system adopts high pressure piston pump and double variable displacement motor, featuring good low speed stability, large drive torque, applicable to the requirements of CZPT work conditions.
The transmission and drive axle of the travel drive system are integrated as one unit; The 2 speed gear special transmission and differential structure features strong drive force and reliable operation.

Efficient material feed/distribution
It adopts chain suspension and anti-block screed technology, which improves the reliability, service life and efficiency of material feed/distribution.

The spiral blade for material distribution adopts high chromel alloy material, large diameter and thickened design, which improves the distribution capability, heavy load impact resistance ability and wear resistance, in addition to large diameter blade and low speed paving, and reduces segregation.

Comfortable to operate
All the operation switches and monitoring instruments are mounted at the control panel, which is simple to operate.

The mobile control panel can be installed at left/right side according to the paving conditions for convenient operation.

The side cover and engine hood is easy to open.

Convenient for repair
There are numbers on all the electric cables, which is convenient to check.
The reasonably allocated pressure measuring points contributes to quick and convenient inspection.
The elements that need to be maintained are installed where they are easy to access.
