● Advanced and reliable control technology

1. The new generation of intelligent integrated paving control system strengthens the intelligent paving operation management function, can monitor and diagnose the functions of the whole vehicle in real time, prompt and guide the operator to complete the real-time processing of the fault.

2. The military-grade switch with intuitive indication and excellent hand feel has superior control accuracy and controllability, and has a good human-computer interaction interface.

3. The intelligent control system can realize automatic calibration according to different hydraulic systems.

4. Innovative use of a new generation of automatic alternating rapid electric heating effectively shortens the heating time of the ironing plate.

5. The imported high-precision intelligent leveling control system is adopted, which has the advantages of high leveling accuracy and strong anti-interference.

● High paving density, good stability and uniformity

1. Double vibration + eccentric vibration mechanical ironing plate, the tamping mechanism has a large excitation force and high pre-compression density.

2. The density automatic control technology based on the principle of equal vibration distance is adopted to effectively improve the density uniformity.

3. The vibrating, vibration, frame and tie rod structures are optimized and reinforced with equal stiffness and equal strength, with high overall rigidity, good paving stability and uniformity.

● Good material delivery and distribution stability and uniformity

1. The left and right delivery and distribution adopt four independent full hydraulic transmissions, and the material level adopts imported ultrasonic sensor control technology to ensure uniform feeding of all proportions.

2. The continuity and stability of the spiral material distribution are improved by optimizing the design of the material distribution spiral blades, support mechanism and control system.

3. The height of the material distribution device from the ground can be quickly adjusted hydraulically to meet the paving requirements of different thicknesses.

4. The new baffle plate structure design and the optimized arrangement of variable pitch blades improve the material conveying flow direction and reduce the occurrence of segregation.

● Strong and reliable walking device

1. The left and right microcomputer-controlled independent hydraulic drive system has better straight-line walking stability and precise tracking and steering performance.

2. The wide track shoes and long ground contact length ensure sufficient traction under various harsh working conditions and maintain the stability of the walking speed.

3. The track hydraulic tensioning device keeps the track in constant tension, maintains the best working condition, reduces loss and maintenance costs.

● Specially designed material receiving device

1. The double cylinder design makes the hopper evenly stressed; with the use of double-section cylinders, the hopper can be folded at a larger angle and the material can be poured more thoroughly;

2. The push wheel adds a spring buffer device to reduce the impact of the docking of the material truck and the paver on the quality of the paved road;

3. The pressure-bearing part of the hopper adopts a box-shaped reinforced structure with high strength and strong anti-extrusion deformation ability.

● Humanized design

1. The control panel with three-dimensional adjustable angle adopts an imported high-brightness display, and the function keys are arranged in logical partitions, which is easy to identify and operate, and has a good human-computer interaction interface.

2. Comfortable and luxurious seats that can be adjusted in multiple directions, a hard driving canopy that can be extended left and right, an overall streamlined cover with noise reduction and sound insulation design, and ergonomic ladders and handrails, all of which provide operators with a comfortable driving environment and driving experience.

3. The automatic centralized lubrication system based on program control ensures reliable lubrication of the bearings in the high-temperature parts of the whole vehicle, prolongs the life of the working mechanism, and reduces labor intensity.

4. The electrical system wiring is neatly arranged, and all electrical circuits and components are clearly numbered, illustrated and named for easy identification, inspection and maintenance.

5. The diesel engine hood and left and right side covers that can be lifted, the neatly arranged integrated valve blocks, and the monitoring points are all placed in easily accessible positions for easy detection, maintenance and maintenance.

● Safe, environmentally friendly and energy-saving

1. It adopts the advanced and reliable Dalian Deutz engine with low noise and low emissions, meets the second-stage emission standards, and is environmentally friendly and energy-saving.

2. The use of new independent heat dissipation technology can automatically adjust the radiator fan speed according to the changes in the diesel engine water temperature, which can effectively reduce noise and energy consumption.

3. The innovative design of automatic rapid electric heating technology enables the entire paving width of the ironing plate to be heated evenly and quickly, which is easy to operate, safe and reliable, environmentally friendly and energy-saving.
