How To Maintain Trucks For Better Durability When Driving Under Different Road Conditions

How to maintain trucks more durable when driving under different road conditions? The road conditions of overseas freight routes vary greatly, with flat highways, steep slopes in mountainous areas, dirt roads on construction sites, and muddy gravel roads alternating. Different road surfaces cause different parts of damage to trucks. If only one maintenance plan is used, it is easy to cause premature damage to components and increase maintenance costs. Adjusting the driving style and maintenance focus based on road conditions is necessary to maintain the stability of the truck and extend its service life. When driving on highways, the vehicle continues to run at a constant speed for a long time, with stable loads on the engine, tires, and braking system. However, the heat dissipation and tire risks are prominent during high-speed driving. The focus of maintenance is on regularly checking tire wear and dynamic balance, paying attention to wheel hub temperature, and changing oil and filter cartridges on time. Do not brake frequently at high speeds for long periods of time to avoid overheating of the brake drum. After each long-distance trip, check the brake pipeline for aging, clean the cooling air duct, and ensure that the cooling system is working properly. Mountainous areas have many slopes and bends, frequent gear shifting and continuous braking, resulting in the fastest wear and tear of clutches and braking components. When going downhill, it is advisable to use engine braking reasonably to reduce overheating caused by prolonged braking. The daily inspection focuses on the thickness of brake pads, brake fluid and air circuit sealing, whether the clutch pedal travel is normal, and at the same time, pay attention to whether there is oil leakage in the transmission. Regularly check the suspension fastening bolts to prevent loosening due to bumps. Construction sites and gravel roads have high levels of dust and gravel, and the intake system is the first to be affected. The air filter is easily clogged, resulting in insufficient engine intake and increased fuel consumption. For this type of road condition, it is necessary to shorten the air filter cleaning and inspection cycle. Regularly check the chassis, frame, and steel plate springs. Gravel can easily scratch the oil and gas pipes, and tires can also be easily punctured by sharp stones. After running on the construction site, simply wash the sand and gravel on the chassis to avoid long-term accumulation of sediment and wear on components. Muddy and slippery road surfaces make it easy for mud and water to adhere to the chassis, axles, and fasteners, accelerating metal corrosion. After running on muddy roads, clean up the mud and sand on the chassis in a timely manner, check the waterproof condition of circuit joints, and prevent short circuits in the circuit. Also pay attention to the anti-corrosion of bearings and locking components, and take necessary protective measures if necessary. The fleet can flexibly adjust the maintenance plan according to the main route of the vehicle, instead of rigidly following a fixed mileage one size fits all approach. Vehicles that frequently run on harsh road conditions should increase the frequency of inspecting vulnerable parts, and drivers should adjust their operating habits according to the road conditions to reduce the additional losses caused by rough driving. The maintenance concept of adapting to road conditions is to focus on areas with high wear and tear, take preventive measures in advance, avoid mid way failures, reduce overseas fleet maintenance expenses, and ensure vehicle attendance.
