How to Choose Scraper Blades for Refuse Trucks and Sweepers?

Why Choosing the Right Scraper Blade Matters

Scraper blades are critical components in refuse trucks and street sweepers. They ensure efficient collection of debris and protect the machine’s working surfaces from excessive wear. Choosing the right scraper blade — whether rubber or polyurethane — impacts not only the cleaning performance but also the lifespan of mechanical parts and overall operating costs. The right choice means fewer breakdowns, reduced downtime, and better efficiency for municipal fleets.

Rubber or Polyurethane Scraper Blades? Understanding the Options

In most municipal vehicles, scraper blades are typically made from one of two materials:

Rubber blades – These are more affordable and flexible but tend to wear out quickly, especially in harsh working conditions such as low temperatures or heavy-duty operations.
Polyurethane blades – Known for excellent abrasion resistance, durability, and resistance to moisture and chemicals. Polyurethane blades last significantly longer than rubber alternatives and are increasingly chosen by municipal service providers seeking to lower maintenance costs.

Key Factors When Selecting Scraper Blades

Several factors determine which scraper blade is right for your vehicle:

Type of vehicle – Different refuse trucks and sweepers require specific blade shapes and sizes.
Working environment – Frequency of use, type of debris collected, and exposure to water or chemicals all affect the choice.
Blade material – Polyurethane is generally preferred in demanding environments or heavy-duty operations.
Hardness and thickness – The blade should be stiff enough to effectively clear debris but flexible enough not to damage mechanical systems.

When in doubt, consulting a specialized manufacturer can help avoid costly mistakes and ensure maximum machine efficiency.

How to Extend the Service Life of Scraper Blades

Proper maintenance helps prolong the lifespan of scraper blades. Here are some practical tips:

Inspect blades regularly and replace them when thickness drops below acceptable limits.
Avoid excessive machine overload.
Choose blades with the right hardness for the surfaces you clean.
For frequent chemical exposure, select polyurethane with enhanced chemical resistance.
