Winter Readiness: Essential Maintenance Tips for AWP’s in Cold Weather
The first month of winter is now behind us, and aerial work platforms (AWPs) are already encountering a new set of operational challenges. Cold weather affects everything from hydraulics to batteries to structural components—making preventative maintenance more important than ever. At RBG Inc., where we proudly offer DINO and HYRAX Aerial Lifts, we know that proper winter readiness doesn’t just protect your investment; it keeps your crews safe and productive when the work can’t wait for warmer weather. Whether you’re managing a small fleet or dozens of lifts across multiple job sites, implementing a comprehensive cold‑weather maintenance plan is essential for reliable performance all season long.
1. Start With a Winter-Grade Fluid Check
Hydraulic systems are the heartbeat of every lift, and cold temperatures can dramatically affect their behavior. In freezing conditions, hydraulic oil thickens, creating sluggish response times, increased wear, and the potential for system strain. Before winter begins, check that your hydraulic fluid meets the manufacturer’s recommended cold‑weather viscosity.
In addition to the hydraulic system, inspect engine oils, gear lubricants, and antifreeze levels. Running with improper fluids can lead to premature wear, reduced efficiency, or system failure at the coldest—and most inconvenient—moments. Our team at RBG Inc. includes this check as part of every annual inspection, but ongoing maintenance throughout the season is just as critical to keeping your equipment performing reliably in cold weather.
2. Inspect and Protect Electrical and Battery Systems
Winter temperatures can be brutal towards electrical components. Batteries lose charge more quickly in the cold, and corroded terminals or failing wiring can worsen the strain. For battery‑powered lifts—common among DINO models—ensure batteries are fully charged before each shift and stored or maintained in a warm environment when possible. Even engine‑powered units rely heavily on healthy batteries for starting and operation.
Check wiring harnesses, connections, and control panel seals for cracks or moisture entry points. Snow, ice, and road salt can infiltrate connectors, leading to intermittent faults or complete shutdowns. A little dielectric grease on terminals and connectors can prevent corrosion and keep conductivity strong throughout the season. If your machine uses a foot pedal, make sure snow, debris, and ice cannot accumulate around it, as buildup can freeze and block proper function. Additionally, ensure the pedal is sealed correctly to prevent moisture from entering and freezing inside, which can damage the connection and compromise operation.
3. Prioritize Regular Lubrication
Cold weather tends to stiffen mechanical joints, pivot points, and extension sections, making consistent lubrication essential. Proper greasing also creates a protective barrier against snow, slush, and road salt. Always clean these areas before re‑lubricating; applying grease over frozen contaminants can trap moisture or abrasive particles, leading to premature wear.
4. Conduct Thorough Pre‑Operation Warm-Ups
Just as vehicles need a few minutes to warm up in cold weather, AWPs benefit from gradual system conditioning before full use. Start the engine or power system and allow hydraulic oil to circulate at low pressure. This reduces the risk of blown hoses or sluggish response when booms first articulate. Warm-up practices are especially important for machines like Hyrax compact lifts, which often operate in tight areas where smooth, precise movement is critical.
Encourage operators to cycle controls gently at first—raising, lowering, and rotating slowly—to allow seals, valves, and cylinders to acclimate to temperature changes.
5. Monitor Tires, Tracks, and Outriggers
Traction and stability become significantly more challenging during winter. For mobile lifts, ensure tires are properly inflated—cold air naturally reduces pressure, increasing wear and decreasing stability. If operating on ice or compacted snow, consider tire chains or approved traction aids.
Outriggers also need careful attention. Always clear snow and ice before deployment and use outrigger pads to prevent slipping or sinking into soft or frozen‑thawing ground.
6. Keep Machines Clean and Salt-Free
Salt and road chemicals accelerate corrosion, especially on lower platforms, boom sections, and chassis components. After operating in winter conditions, wash lifts regularly—paying special attention to undercarriages and metal structures. Keeping slush and salt buildup off your equipment prevents long‑term rust, protects wiring, and improves reliability.
7. Store Equipment Properly Between Shifts
Whenever possible, store AWPs indoors or under cover during freezing weather. Cold storage drains batteries, thickens fluids, and increases condensation risk. If indoor storage isn’t available, use engine block heaters, battery blankets, and weatherproof covers to protect critical components.
Final Thoughts
Winter readiness isn’t just about avoiding downtime—it’s about keeping your crews safe and extending the lifespan of your AWPs. With proper preparation and consistent maintenance practices, DINO and Hyrax lifts operate reliably even in harsh New England winter conditions.
