Ready or not, winter is coming. As it approaches, it is crucial for municipalities and contractors to prepare their street sweepers for the harsh conditions ahead. Proper winterization ensures that sweepers remain in top working condition, ready to tackle the challenges of snow, ice and debris.

Here are the top nine essential tips for winterizing street sweepers to maintain their efficiency and longevity throughout the colder months:

1) Thorough Cleaning and Inspection – Before winter sets in, give your street sweeper a thorough cleaning. Remove all debris from the hopper, brushes and other components. This is also an excellent time to inspect the sweeper for any signs of wear or damage. Look for cracks, rust or other issues that could worsen in cold weather. Addressing these problems early can prevent costly repairs down the line.

2) Drain and Protect Water Systems – Water systems are particularly vulnerable to freezing temperatures. For long-term storage, drain all water from tanks, hoses and pumps to prevent ice from forming and causing damage. For sweepers that are in-service during colder months, consider using a non-toxic antifreeze solution in the water system. This step is crucial for sweepers that use water for dust suppression.

3) Battery Maintenance – Cold weather can significantly reduce battery performance. Whenever the battery is not in use, store the sweeper and installed battery in an environment that is thermally controlled. Fully charge the high voltage battery before placing the system in extended storage.

4) Fuel System Preparation – Condensation can form in field tanks during cold weather, leading to water contamination. To minimize this risk, fill the fuel tank to reduce the amount of air inside. Adding a fuel stabilizer can also help prevent fuel degradation. If the sweeper will be stored for an extended period, consider draining the fuel system entirely.

5) Lubrication and Fluid Checks – Cold temperatures can cause lubricants to thicken, reducing their effectiveness. Check all fluid levels, including engine oil, hydraulic fluid and coolant. Replace any fluids that are due for a change and use winter-grade lubricants where appropriate. Regularly lubricate moving parts to ensure they operate smoothly in cold conditions.

6) Protecting Exposed Metal Surfaces – Winter conditions can accelerate the corrosion of metal components. Apply a corrosion inhibitor or grease to exposed metal surfaces to protect them from rust and other damage. Pay special attention to areas that are prone to moisture accumulation, such as joints and hinges.

7) Brush and Broom Care – Inspect the brushes and brooms for wear and damage. Replace any worn or damaged components to ensure optimal sweeping performance. Adjust the broom settings to account for the different types of debris encountered during winter, such as sand and salt.

8) Storage Considerations – If the sweeper will be stored for an extended period, take additional steps to protect it. Store the sweeper in a dry, sheltered location to shield it from the elements. Cover the sweeper with a tarp or other protective covering to prevent moisture buildup. Ensure that all drains are open to allow any remaining water to escape.

9) Operator Training – Proper training is essential for maintaining street sweepers in winter. Ensure that operators are familiar with the winterization procedures and understand the importance of regular maintenance. Provide training on how to operate the sweeper in winter conditions, including techniques for handling snow and ice.

By following these winterization tips, municipalities and contractors can ensure their street sweepers remain reliable and efficient throughout the winter months. Proper preparation not only extends the life of the equipment but also helps protect the public by maintaining clean and safe streets, even in the harshest conditions.
