Harsh winter weather can wreak havoc on outdoor vehicles and equipment, and aerial lift trucks are no exception. Low temperatures reduce material flexibility, and moisture that settles into small cracks can freeze, expand and accelerate wear. Buckets and liners experience more direct winter exposure than most other components, which makes seasonal maintenance especially important for them.
This guide outlines practical steps to prepare your aerial lift for winter operation with a clear focus on bucket and liner care.
Conduct Early Winter Aerial Lift Inspections
Start the winter strong by inspecting your aerial lift for winter readiness. Any existing issues typically worsen once equipment is exposed to repeated freezing cycles, so it’s critical to address them before the cold sets in.
Cold weather affects hydraulics, seals, control systems and electrical components, so each should be scrutinized. Once the core system is confirmed to be operating correctly, shift attention to the components that carry the most winter exposure. Buckets and liners should be evaluated with extra care because they experience direct contact with ice, snow and freezing moisture.
Check for:
-
- Surface cracks or fractures in the fiberglass
-
- Areas showing dulling, UV wear or gelcoat thinning
-
- Gouges or abrasions caused by tools or debris
-
- Signs of delamination or soft spots
-
- Liner fit issues such as warping, gaps or shifting
Consider Replacements
You may find it is time to replace your bucket or liner. Better to plan for a replacement than face unexpected downtime at the most inopportune time. A bucket replacement can keep a truck out of service for several days. Better to fit it with a liner or replace it altogether on your schedule than to be blindsided.
Your polyethylene bucket liner should be replaced if you notice:
-
- Deep gouges or worn areas that catch tools during use
-
- Distorted areas that indicate the liner no longer sits flush
-
- Fractures that grow under pressure
-
- Any separation from the bucket wall
A new or properly fitted liner reduces the risk of structural damage and helps extend the bucket’s life throughout a harsh winter season.
Protect Cycles Against Moisture and Freeze
Moisture is one of the most damaging winter variables. Water that finds its way into cracks, seams or worn gelcoat can freeze at night, expand and widen any existing defects.
To minimize this risk:
-
- Keep buckets and liners clean and dry before storage
-
- Inspect for spots where moisture can accumulate
-
- Remove snow and ice after each shift rather than allowing it to melt and refreeze
-
- Store equipment under cover whenever possible
Bucket covers can provide an added layer of protection by limiting ice buildup, blocking snow and reducing the amount of freeze-related stress inside the bucket.
Use Safe Cleaning and Deicing Practices
Cleaning and deicing require extra care during winter. Some chemicals used for ice removal can damage fiberglass or weaken a polyethylene liner over time.
Recommended practices include:
-
- Use mild, non-abrasive cleaners to remove dirt and salt
-
- Avoid harsh solvents that break down gelcoat or plastic
-
- Use warm water to loosen ice rather than mechanical scraping, which can damage the surface
-
- Remove ice in layers rather than prying or chiseling
Daily Winter Operation Checks
Cold temperatures change how equipment behaves throughout the workday. A quick inspection before each shift helps catch issues early and reduces safety concerns.
Operators should:
-
- Ensure the liner is fully seated with no visible gaps
-
- Check that steps, bucket edges and inside surfaces are free of ice
-
- Confirm tools are not creating new abrasions inside the liner
-
- Look for condensation or minor moisture buildup
-
- Remove any frozen material that could affect footing or stability
Prepare for Top Performance
Winter conditions place additional strain on aerial lift equipment, especially on buckets and liners. By inspecting your equipment early, maintaining a proper liner fit, replacing equipment early and reducing exposure to moisture and freezing cycles, you help protect operators and prevent unnecessary downtime.
