Functions:
1. Ensure normal equipment operation
- Prevent excessive chain wear: Reduce direct friction between the
chain and other components, such as installing wear-resistant
linings on the chain track, which can extend the chain's service
life and avoid failures like chain breakage.
- Avoid chain jams: Block and filter debris in the material to
prevent it from getting into the gaps between the chain, sprocket,
or scraper, ensuring smooth chain operation.
2. Guarantee construction quality
- Stabilize the material conveying volume: Maintain the stable
operation of the scraper chain to ensure a uniform material
conveying speed and quantity, which is crucial for the smoothness
of the paved road surface.
- Prevent material accumulation or segregation: Ensure the normal
distribution of materials in front of the paver's screed, avoiding
uneven material distribution and ensuring the performance and
quality of the road surface.
3. Reduce maintenance costs and downtime
- Decrease maintenance frequency: Extend the chain's service life
and reduce the occurrence of chain failures, saving maintenance
costs and downtime, and improving equipment utilization.
- Facilitate troubleshooting and maintenance: Some protection
devices have monitoring and warning functions, enabling early
detection of potential problems and making maintenance more
efficient.
4. Enhance operational safety
- Prevent flying parts from injuring people: Enclose the scraper
chain to prevent parts from flying out in case of chain failures,
protecting the safety of operators.
- Avoid equipment out of control: Reduce the risk of chain
failures, ensuring the safe and stable operation of the paver and
preventing safety accidents caused by equipment malfunctions.
