The APOLLO Abrasion-Resistant Knife Plate: A Critical Component for Paver Longevity and Performance
In the demanding world of road construction, the asphalt paver is the centerpiece of operation, tasked with laying a smooth, consistent, and durable mat of hot mix asphalt. The heart of this machine is the screed, which heats, levels, and provides the initial compaction to the material. Protecting this vital component from relentless wear is not merely a maintenance concern—it is essential for operational efficiency and final pavement quality. The APOLLO Abrasion-Resistant Knife Plate, identified by part number 2123654, is a consumable part engineered specifically for this critical protective role.
This component is designed as a direct-fit replacement for specific models of asphalt pavers, namely the SB250-2TV and SB300-2TV screed assemblies. This precise compatibility ensures seamless integration, maintaining the original equipment's geometry and performance. The knife plate, sometimes referred to as a wear plate or a screed plate, is strategically positioned at the front of the screed. Its primary function is to act as a sacrificial barrier. As tons of hot, coarse, and highly abrasive asphalt mix are pushed and flowed underneath the paver, the knife plate bears the brunt of the friction, preventing direct contact and subsequent damage to the more expensive and structurally critical main body of the screed itself.
The most defining characteristic of this part is its Abrasion-resistant quality. This is not a standard steel plate; it is manufactured from a specially formulated, hardened material designed to withstand extreme wear. The constant scraping and rubbing by aggregate-filled asphalt would quickly degrade ordinary steel, leading to premature failure, irregular mat thickness, and costly downtime for replacements. The APOLLO Knife Plate's enhanced resistance ensures a significantly extended service life, reducing the frequency of change-outs and the total cost of ownership over the machine's operational lifespan.
Furthermore, this part is offered as part of a Kit, which is a significant practical advantage. The kit format guarantees that the user receives all necessary components for a complete installation. This typically includes the knife plate itself and may also include specialized, high-strength bolts, nuts, or other fasteners required for a secure and correct fit. This eliminates guesswork, saves valuable time for maintenance crews, and ensures the part is installed according to manufacturer specifications, which is crucial for optimal performance.
In essence, the APOLLO Abrasion-Resistant Knife Plate is a prime example of a focused engineering solution. It directly addresses one of the most intense wear points in the asphalt paving process. By protecting the screed assembly on compatible models like the SB250-2TV and SB300-2TV, this kit helps maintain the paver's precision, ensures a consistent quality of the asphalt mat, and ultimately contributes to the creation of smoother, longer-lasting roads. It is a small but indispensable component that plays a large role in the economics and effectiveness of modern road construction.
