Product Operate Guide
Before starting work, check the status of the equipment and preheat the ironing plate to the specified temperature. After startup, conduct no-load tests on the walking, material conveying and distribution, and vibration systems. Coordinate with the material cart during paving, activate the automatic control function, and maintain uniform and continuous operation. Closely monitor the material level and flatness. All components must be thoroughly cleaned immediately after completion to prevent the asphalt from solidifying. Strictly follow the safety regulations. For details, be sure to refer to the random operation manual.
FAQ
A: This model adopts a hydraulic telescopic screed with a basic width of 2.5 meters. By adding segments, it can be extended to a maximum of 4.5 meters (which is also the meaning of "453" in the model). The maximum paving thickness can reach 300mm, which can meet the needs of the vast majority of conventional paving operations.
What are its features?
A: RP453L is usually equipped with turbocharged diesel engines from well-known brands (such as Deutz), with a power output of approximately 100kW. This engine features strong power, low fuel consumption, low noise, and compliance with National III/IV emission standards. It can provide stable and reliable power output and adapt to various harsh working conditions.
A: It adopts four sets of screw material distribution systems driven independently on the left and right sides and a scraper material conveying system. The height of the material distribution trough can be automatically adjusted, which can effectively ensure the uniformity and sufficiency of material transportation and reduce segregation. This is a key prerequisite for ensuring the flatness of the paving.
A: The ironing plate of RP453L usually adopts the heating method of liquefied gas (LPG). Its advantages are uniform heating, fast speed, precise temperature control, environmental friendliness and no pollution. It can quickly reach the working temperature, improve construction efficiency and ensure the quality of the surface of the paving layer.
A: This model adopts an intelligent electro-hydraulic control system. It is equipped with a multi-functional control panel (human-machine interaction interface), which can precisely control the main functions such as paving speed, material conveying and distribution speed, and the lifting of the ironing plate. Some high-end models may also be integrated with an intelligent leveling system, which automatically controls the paving thickness and flatness through ultrasonic or laser sensors.
A: Common faults are mostly concentrated in:
• Difficulty in starting the engine: Check the battery power, fuel level, and whether the filter is clogged.
• Poor paving flatness: Check the wear of the ironing plate base plate, whether the heating is uniform, and whether the sensors of the leveling system are normal.
• Poor material distribution: Check the tension of the chain, the wear of the scraper, and the sensitivity of the material level sensor.
• Deviation during walking: Check whether the tension of the tracks is consistent and whether the walking motor is working properly.
