The 146456 conveyor belt scraper blade is a replacement component designed for discharge conveyor systems on Wirtgen cold road milling machines. This part sits in contact with the conveyor belt surface to remove residual asphalt and concrete material during road milling, pavement recycling, and large-scale excavation operations. It is engineered for use in road construction and maintenance settings, and is not intended for metal milling or CNC machining equipment. This component supports consistent conveyor operation during commercial paving and roadwork projects, and fits standard maintenance schedules for heavy construction equipment.
This scraper blade is constructed from polyurethane material, with a rated operating temperature range of -20°C to 80°C. The material is formulated to create firm contact with conveyor belt surfaces without cutting or abrading the belt fabric during regular operation. The blade is manufactured to uniform dimensions to maintain consistent contact pressure across the full width of the conveyor belt, matching the specifications of original equipment components for cold milling machines.
During milling operations, loose asphalt and concrete aggregate adheres to the textured surface of the discharge conveyor belt. Without regular removal, this carried material travels back along the return side of the belt, where it can build up on return pulleys and guide plates. This buildup causes belt misalignment, uneven wear on belt edges, and accelerated wear on rotating conveyor components. The scraper blade dislodges adhered material as the belt moves past the blade position, reducing material carryback along the return belt path. This action also reduces the volume of milled material left on the conveyor structure, cutting down on manual cleanup time for maintenance crews during scheduled service stops.
This scraper blade is manufactured to match the installation dimensions of original equipment parts for select Wirtgen cold road milling machine models. Direct fitment applies to W2000, W2100, W2200, W1900, W150, W100, and W120 series cold milling machines. The blade matches the hole spacing and contact angle specified for these models, to align with factory mounting points on the conveyor frame. This part is not compatible with metal milling machines, CNC machining centers, or light-duty conveyor systems not designed for road construction material handling.
The 146456 scraper blade uses a bolt-on mounting design, with pre-set mounting holes that align with existing holes on the conveyor scraper assembly. Installation does not require drilling, welding, or modification to the conveyor frame or existing mounting hardware. Maintenance crews can complete replacement during standard service intervals without specialized fabrication equipment, reducing equipment downtime during active construction projects. The blade is sold as an individual replacement unit, to allow replacement of worn blades without full assembly replacement when other scraper system components remain within wear tolerances.
This scraper blade is categorized as a wear part for cold milling machine conveyor systems. Crews should inspect the blade edge for wear during each routine service interval, typically alongside daily or weekly equipment checks. When the blade edge wears to a point where consistent contact with the belt surface is no longer maintained, or when material chunks begin to pass the blade and accumulate on return components, the blade should be replaced. Operating the conveyor with a severely worn scraper blade can allow aggregate to become trapped between the belt and pulleys, leading to belt damage that requires full conveyor belt replacement.
When performing full conveyor system maintenance on compatible milling machines, this scraper blade is often replaced alongside other wear components in the scraper and conveyor assembly. Matching parts for coordinated service include the Scraper Blade Kit (part number 194410), replacement conveyor belt, Return Pulley (part number 111225), and Guide Plate (part number 112519). Maintenance teams can reference equipment service manuals to check wear tolerances for each of these components during scheduled overhauls, to reduce unplanned downtime during active milling projects. For enterprise customers managing large milling fleets, stocking these common wear parts supports consistent equipment uptime across multiple job sites.

This scraper blade is engineered for Wirtgen W2000, W2100, W2200, W1900, W150, W100, and W120 series cold road milling machines used in road construction and pavement maintenance. It is designed for the discharge conveyor systems of these heavy construction machines, and is not compatible with metal milling equipment, CNC machining centers, or light-duty industrial conveyors.
No modification is required for installation. The blade uses a bolt-on design with pre-aligned mounting holes that match factory mounting points on compatible conveyor assemblies. Installation can be completed with standard hand tools during routine maintenance, without drilling, welding, or alteration to the machine frame.
This scraper blade comes with a 1-year warranty, covering defects in material and workmanship under normal use in industrial road construction applications. The warranty does not cover normal wear from contact with construction aggregate, or damage caused by improper installation, use outside the rated temperature range, or operation on non-compatible equipment.
