ZT600 maintenance paver is an XRMC developed international advanced pavement machine.
ZT600 maintenance paver is an XRMC developed international advanced pavement machine, in which the high performance paving technique and the advanced emulsified asphalt spraying technique are integrated perfectly.The emulsified asphalt spraying system is equipped behind the apron wheel of asphalt paver so as to cover an asphalt layer on the just paved emulsified asphalt in only several seconds. This machine is used in the preventative maintenance engineering while the wearing course of the high-grade road is disabled. The repaved wearing course can prolong the service life of the high-grade road. The spraying operations of emulsified asphalt and asphalt are finished together, so ZT600 can save time, labor and material. The high construction efficiency and compact structure are incomparable for any former familiar machines.
The machine can spray the emulsified asphalt and asphalt thin bed synchronously or respectively.
The CAN bus network control technology is adopted and some advanced and some novel design thinking of transmission of power, fluid pressure control and human engineering are introduced.
The central elements of driving system, hydraulic system and electric appliance are all imported from the famous companies of Germany and the U.S. such as American SAUER, FIELD, MOBA, and German GESSMANN etc. These high grade elements ensure the reliability of ZT600.
The QSB6.7 engine, with ECU control and 164kw/2300rpm, is imported with original packaging from Cummins Company of Germany. The imported air pre-filter prolongs the service life of air filter.
The coordination of the spray speed of emulsified asphalt and the paving speed of asphalt are auto-controlled, so the functions of constant speed driving and stringent control are realized.
The 4m3 emulsified asphalt bin has the functions of automatic heating and heat preservation. The supply system and recycle system of emulsified asphalt can effectively guarantee the spray operation.
The idiographic design of double screw conveyor has the powerful conveying capability. The electric heater is installed around the trough to prevent the conglutination of asphalt.
The screw conveyer and the screw distributor are driven with hydraulic systems respectively. The feeding of material is auto controlled with the untouched material-level sensor.
The double cooling circuit provides a good working condition for the hydraulic system.
Equipped with the central auto lubrication system, auto lubricated screw conveyer and distributor and the high performance cleaning system of diesel oil, so the cleaning and maintenance is convenient and fast.
Spraying system and screed equipment are telescoped together. The maximum spraying width can reach 6m. The pneumatic nozzle, with the function of self-cleaning, can be remote-controlled and closed independently.
The slip seat can be moved out of machine, so the eyeshot is open and the driving becomes safe enough.
The mobile master console and remote control box make the operation be more flexible, convenient and reliable.
The foldaway ceiling provides a good working environment for operator and facilities the transfer and transport.
