4812064058 Tamper bar for AB500

Product Introduction:

The Tamper bar of the AB500 paver's screed system is a core component in the pre-compaction stage of asphalt paving. Installed at the front of the screed, it acts on the paving layer through high-frequency reciprocating impact, laying a foundation for subsequent roller compaction. Made of high-strength alloy steel, it has excellent wear resistance and impact resistance, capable of withstanding friction from high-temperature asphalt mixtures and operational impacts for a long time, and adapting to various paving conditions. During operation, the Tamper bar moves synchronously with the screed, enhancing the compactness of the paving layer through impact, reducing the risk of subsequent pavement settlement, and directly affecting pavement flatness and service life. In addition, the Tamper bar adopts a modular design, allowing easy disassembly and assembly for daily maintenance and replacement. Its operating parameters can be adjusted according to paving material characteristics and construction requirements, making it a key part to ensure stable paving quality.

What are the common malfunctions of pavers?

Common faults of the AB500 paver mainly focus on the screed system, hydraulic system and electrical control system: the screed system is prone to uneven wear of tamper bars, uneven heating or deformation of the screed, leading to poor flatness of the paving surface; the hydraulic system may have valve group jamming or oil pipe leakage, causing slow lifting of the screed and abnormal vibration frequency of the tamper; the electrical system is likely to have sensor failure, resulting in wrong parameter display or automatic control failure; the Undercarriage system occasionally has track deviation and drive motor faults, affecting the stability of paving speed; in addition, auger feeder jamming and scraper conveyor chain are also common, leading to uneven feeding and affecting paving continuity. These faults are mostly related to insufficient daily maintenance, improper working condition adaptation or component aging.

How to maintain the screed system of an AB500 paver?

Maintenance of the AB500 paver's screed system focuses on core component care and working condition adaptation: check the wear of tamper bars before operation, replace them promptly if there is uneven wear or cracks, and clean asphalt mixture stuck to the screed base plate to avoid affecting paving flatness; inspect the heating system regularly to ensure electric heating rods or gas heating modules work normally, preventing base plate deformation due to uneven heating; lubricate telescopic guide rails and tamper drive connecting rods with high-temperature resistant grease to reduce mechanical wear; clean the screed immediately after operation, remove residual asphalt with diesel, and apply anti-rust oil after drying; detect tamper vibration frequency and amplitude every 500 working hours, calibrate control system parameters to adapt to different asphalt material characteristics; in addition, check screed flatness regularly and perform straightening if necessary to ensure long-term operation accuracy.
