Understanding Winter Weather Hazards

Extreme temperatures, heavy snowfall, and icy conditions present unique challenges for operating heavy equipment during winter months. Proper preparation and maintenance are crucial for withstanding winter weather hazards and ensuring safe, productive operation throughout the colder seasons.

Extreme Cold Temperatures

Extreme cold temperatures can cause significant issues for heavy machinery and increase maintenance demands. Sustained low temperatures may cause hydraulic fluids, engine oil, and diesel exhaust fluid (DEF) to thicken or freeze altogether.

Hydraulic fluids and engine oil specifically help lubricate moving parts and seals, so thickened or frozen fluids cannot adequately perform these functions. DEF also has a higher freezing point than water, so it is more prone to freezing solid in colder weather. If DEF freezes in the tank or lines, the equipment may not run or function properly.

To combat these cold-related problems, operators should install block heaters on engines to keep internal components warm even when the equipment is not in use. An internal tank heater can also be used to maintain DEF and hydraulic fluids in a fluid state.

Operators should also use higher-viscosity oils formulated for colder temperatures as they are less prone to thickening. Performing regular maintenance like fluid changes helps remove moisture and contaminants that accelerate freezing.

Keeping fluids, batteries, and the entire cooling system at optimal levels mitigates issues from extended periods of extreme cold.

Heavy Snowfall

Heavy snowfall can impede operation and increase safety risks for heavy equipment. Snow packs down and forms dense layers of ice and packed snow on roadways and work sites. These conditions put additional stress on undercarriage components like tracks, rollers, and idlers.

The added weight and friction of packed snow and ice lead to uneven wear that must be addressed through more frequent undercarriage inspection and maintenance.

To prepare for heavy snowfall, operators should inspect the undercarriage and tracks for any issues prior to the winter season. They should also maintain proper track tension, which prevents slippage and damage in icy conditions.

Operators must also be aware that heavy snow can accumulate rapidly in areas that equipment has trouble reaching, like atop structures or around outriggers. Regular clearing is needed to prevent unsafe buildup. Additional ballast may also be required in some cases for stability.

Icy Conditions

Icy conditions pose a serious safety hazard. Slick surfaces can cause equipment to lose traction or control. Frozen precipitation also increases the risk of slipping or falling when accessing or operating machinery. To mitigate these risks, operators must take special precautions. All walking and working surfaces should be treated with de-icing materials. Extra care is needed when entering or exiting the operator cab.

Equipment must be prepared with the proper tires or tracks as well. Pneumatic tires require higher than normal pressure to cut through ice buildup. Tracks need to maintain optimal tension to provide traction.

Both tires and tracks should be checked daily along with fluid levels to ensure safe operation on icy surfaces. With diligent preparation and maintenance of the equipment, operators can minimize safety risks from icy conditions and complete work efficiently even in challenging winter weather.

Inspecting and Servicing your Equipment

Winter weather places additional stress on heavy machinery, making thorough inspections and servicing crucial for safe operation throughout colder months. By addressing key components before temperatures drop, operators can minimize downtime and costs associated with winter maintenance.

Check Hydraulic and Fuel Lines

Hydraulic and fuel lines must withstand freezing temperatures and ensure a steady fluid supply. Prior to winter, operators should inspect all lines for leaks, cracks, or other damage that could worsen in extreme cold. Pay close attention to connections and fittings, which are prone to corrosion. Replace any worn parts and coat exposed lines with insulation to prevent freezing.

Operators should also check fluid levels in hydraulic tanks and fuel tanks, adding proper fluids as needed. Maintaining optimal fluid levels mitigates moisture and contaminant buildup that accelerates freezing.

Inspect Cooling System

Keeping the cooling system at peak efficiency is vital to dispersing heat in colder weather. Inspect the entire cooling system, including coolant lines and radiator, for leaks. Test coolant concentration with a refractometer and replace diluted coolant that offers less protection against freezing.

Inspect water pumps, thermostats, and fans for proper functioning as well. Catching issues like coolant leaks before temperatures drop means avoiding potentially serious damage from overheating or freezing.

Test the Battery and Electrical System

Cold weather puts additional strain on electrical components, so testing the battery and full electrical system now allows time for replacement if needed. Check battery terminals and cable ends for corrosion, and clean or replace them as needed.

Also, check electrolyte levels and charge state. Inspect the starter, alternator, and all electrical connections and wiring for integrity. Catching electrical issues proactively prevents cold start failures.

Check Brakes and Tires

Brakes and tires are high-priority winter components. Inspect air brake lines and valves, testing for leaks and smooth operation. Also, inspect hydraulic brake fluid levels and condition. Check tire pressure and tread depth, inflating or replacing tires if underinflated or worn.

For solid tires, inspect for cracks and check lug nuts for proper torque. Proper tires and brakes are key to navigating slippery winter conditions safely.

Winterizing the Engine

The engine works hardest in frigid temperatures and requires special preparation to withstand winter conditions. Taking steps to winterize the engine helps prevent damage and keeps equipment functioning reliably.

Change to Winter-Grade Oil

One of the most critical tasks is changing engine oil to a winter-grade variety. Oil with a higher viscosity does not thin out as much in colder weather, maintaining its lubricating properties down to lower temperatures. Look for oil rated 0W-40 or 5W-30 for best protection in extreme cold.

Switching to winter-grade oil before temperatures drop below freezing helps ensure components receive adequate lubrication during operation.

Add Engine Additives

Using a fuel additive designed to prevent gelling is also recommended, especially in equipment that will be exposed to freezing temperatures for extended periods. Additives lower the fuel’s gel point so it does not solidify in the tank, lines, or fuel filter.

They also improve combustion and inhibit corrosion. Adding the recommended dosage of additive during an oil change prepares the fuel system for reliable cold starts.

Ensure Proper Antifreeze Levels

Check antifreeze and coolant levels, conditioning, and concentration before winter. Coolant protects down to much lower temperatures than plain water but must be at the proper concentration for this protection.

Add premixed antifreeze/coolant if levels are low according to manufacturer recommendations. Proper antifreeze concentration is vital to prevent freezing and overheating that can damage the engine.

Protecting Exposed Components

Winter weather poses unique risks for machinery left outdoors. Taking steps to safeguard sensitive components helps prevent freeze damage and corrosion when equipment sits idle.

Cover Sensitive Electronics

Exposed electronics are vulnerable to moisture and temperature fluctuations. Before storage, cover components like sensors, monitors, and wiring harnesses with breathable, weatherproof covers. Look for covers rated for extreme cold and snow-rated for full protection without restricting airflow.

Protecting sensitive electronics protects against freeze damage, overheating, and corrosion to ensure reliable performance when work resumes.

Apply Grease to Hinges and Locks

Greasing hinges and locks protect moving metal parts from corrosion caused by road salt and moisture. Apply thick, winter-grade grease to exposed door hinges and locks, lift arms and any other moving joints. Greasing protects parts and helps prevent freezing or seizing that could damage components or hamper operation.

Install Snow Covers or Cab Enclosures

For equipment left outside, install snow covers or cab enclosures to deflect accumulating snow. Heavy snow buildup adds extra weight and stress. Covers also shield interiors from moisture, preventing interior corrosion and freeze damage.

Look for covers rated for withstanding high winds and made from weather-resistant materials like vinyl-coated polyester for maximum protection in extreme conditions.
