[Product Description]
Reliable drive system
Efficient feed/ material distribution system
Efficient control system
Strong CZPT system
Advanced screed technology
Technical features
Power drive technology: efficient and CZPT ful
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/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 CZPT , 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 CZPT ng technology, in addition to electro-hydraulic controlled conveying speed, which ensures automatic control of the height of mixed materials in CZPT 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 CZPT ng mode are CZPT , 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 CZPT paving conditions.
The screed lifting cylinder has floatation and lock up function, applicable to CZPT paving materials and work conditions.
It can be equipped with eccentric vibration device.
Performance advantages
Excellent configuration
The CZPT ful 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 50ºC.
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.
