Tanker trailers are critical in transporting liquids, from fuel and chemicals to food-grade products like milk and juice. Keeping them in top condition is essential for safe, efficient, and environmentally friendly operations.
However, like any piece of equipment, tanker trailers are prone to wear and tear. Understanding the 10 most common fail points on a tanker trailer is the first step in maintaining safety and performance while preventing costly downtime.
Understanding Tanker Trailers
Tanker trailers are specialized vehicles that transport large volumes of liquids or gases. They have specific designs, materials, and features depending on their intended use. Food-grade tankers, for example, prioritize hygiene and easy cleaning, while chemical tankers require corrosion-resistant materials and internal linings.
These trailers play a vital role in keeping industries running smoothly. Theyโre engineered to withstand heavy loads and challenging conditions. However, even the best-designed tanker trailers can experience issues if not properly maintained. For fleet managers, operators, and maintenance professionals, knowing the anatomy of these vehicles and their potential weak points is essential for ensuring safe and reliable operations.
The Importance of Recognizing Tanker Trailer Fail Points
Ignoring the warning signs of potential fail points on a tanker trailer can lead to serious consequences. From hazardous material spills to increased fuel consumption and inefficiencies, even minor issues can spiral into major problems if left unaddressed. Proactive maintenance enhances safety, reduces downtime, saves money, and extends the lifespan of your equipment.
Recognizing these fail points allows operators and fleet managers to implement preventive measures before failure occurs. This improves operational peace of mind and avoids regulatory penalties linked to unsafe equipment on the road.
Common Tanker Trailer Fail Points
While tanker trailers are designed for durability, they are not immune to the stresses of regular use. Here are the 10 most common fail points and how they can jeopardize trailer performance and safety.
1. Brake System Failures
Braking systems are essential for the safe operation of tanker trailers, particularly since these vehicles transport heavy, shifting loads. Standard brake system issues include worn brake pads, malfunctioning air lines, or improper adjustments. These failures can significantly reduce brake efficiency, increasing stopping distances, which may endanger the driver and others on the road.
2. Corroded Tank Surface
Tanker trailers are frequently exposed to harsh chemicals, rain, and rough road conditions, all of which can cause corrosion on the tankโs exterior and interior surfaces. Corrosion compromises structural integrity, leading to weakened tanks and potential leaks. This corrosion poses even more significant risks for chemical tankers as it may result in exposure to hazardous materials.
3. Valve Leaks
Valves are crucial for controlling the flow of liquids during loading and unloading. Over time, they can deteriorate or wear out, causing leaks. Leaks result in product loss and can cause environmental damage, regulatory issues, or hazardous exposure for employees.
4. Damaged Hose Connections
Frequent use and exposure to corrosive substances can lead to cracked, kinked, or worn hoses. Damaged hose connections can cause inefficiencies during loading and unloading and the risk of fuel or chemical spills.
5. Suspension Issues
The suspension system absorbs impacts from the road while carrying the heavy weight of the tank and its cargo. Over time, components like springs and shock absorbers can fail, leading to unstable handling, uneven weight distribution, and excessive wear on other parts.
6. Internal Tank Lining Damage
Internal tank linings are essential for trailers that transport corrosive or specialized liquids. However, these linings can degrade or peel over time, particularly if they are improperly maintained. A damaged tank lining makes the tanker unsuitable for some cargo and increases the likelihood of contamination or leaks.
7. Lighting and Electrical Problems
Lighting and electrical systems, such as brake lights, turn signals, and wiring, ensure visibility and safety for tanker trailer operations. Faulty wiring, bulb failures, and short circuits are common issues that may lead to accidents, citations, or operational hazards.
8. Tire Wear and Blowouts
The heavy loads carried by tanker trailers place immense pressure on tires. Excessive tire wear can lead to dangerous blowouts without routine inspection and maintenance. Blowouts are a safety concern and can cause delays and unexpected expenses.
9. Manhole Cover Failures
The manhole cover provides essential access to the tank while maintaining a secure seal. Over time, faulty gaskets, warped covers, or improper fittings can cause leaks and compromise the tankโs airtightness, increasing the risk of spills and contamination.
10. Overfill Protection System Failures
The overfill protection system is designed to prevent tanks from being filled beyond capacity. Malfunctions in this system can lead to unsafe operations during loading, increasing the danger of spills or operator injury.
How To Address Fail Points
Girard can help with Valve Leaks and manhole cover failures; many other companies specialize in these areas. However, proactive and regular maintenance is the best way to address these common failing points for any product found on a tanker trailer. Ignoring maintenance can lead to costly repairs or replacements when equipment fails unexpectedly.
Conduct Routine Inspections
Create a schedule for regular tanker trailer inspections. Consider critical components like brakes, suspension, valves, and hoses. Look for early signs of wear, such as rust, cracks, improper seals, or excessive tire degradation.
Follow Manufacturer Guidelines
Always adhere to the manufacturerโs recommendations for maintenance procedures. Specific hoses or valves may have lifespan guidelines, and maintaining them could prevent leaks or failures.
