The temptation to save a few dollars on a non-certified tank is a gamble no responsible operator can afford. The cost of an accident far outweighs any perceived savings.
Tip 2: Inspect Regularly, Even When There’s “Nothing” Wrong. Aluminum may resist rust, but it is not impervious to damage. Develop a routine inspection schedule that includes a thorough visual examination of the tanks surface. Look for signs of dents, cracks, or corrosion around fittings. Pay particular attention to mounting brackets, as these are prone to stress fractures. Early detection of even minor issues can prevent a major failure down the road. Imagine a hairline crack, unnoticed, slowly widening under pressure, until the entire tank gives way at a critical moment. Vigilance is the ultimate safeguard.
Tip 3: Match Tank Size to System Demand, Not Just Available Space. Over- or under-sized tanks can compromise the efficiency and safety of the air system. Consult with a qualified technician to determine the appropriate tank volume based on the specific braking system and auxiliary equipment on the truck. An undersized tank may struggle to maintain adequate air pressure during heavy braking, while an oversized tank can add unnecessary weight and increase compressor cycling. The ideal tank is perfectly balanced to the demands of the system.
Tip 4: Protect Against Galvanic Corrosion, A Silent Threat. When dissimilar metals, such as aluminum and steel, come into contact in the presence of an electrolyte (like road salt), galvanic corrosion can occur. To prevent this, use dielectric isolators between the tank and any steel mounting brackets or fittings. These simple insulators create a barrier, preventing the flow of electrons and minimizing corrosion. Neglecting this step can lead to premature failure of the tank or its connections.
Tip 5: Train Drivers on Proper Air System Management, A Preventative Measure. Educated drivers are the first line of defense against air system problems. Ensure that drivers understand the importance of regularly draining moisture from the air tanks, as excessive moisture can accelerate corrosion and damage internal components. Train them to recognize the signs of air system leaks, such as excessive compressor cycling or reduced braking performance. Empowered drivers are more likely to identify and report potential problems before they escalate into major issues.
