Pay Attention To These Points in Daily Trailer Operation To Ensure More Stable Cargo Handling

Pay attention to these points in the daily operation of trailers, as they are more stable in handling goods. Many fleets focus on the maintenance of trailers and often ignore them. In fact, trailer failures are also a high incidence of breakdowns and transportation delays, especially in complex overseas road conditions and scattered maintenance outlets. Conducting daily inspections of trailers can significantly reduce operational risks and unnecessary losses. The first thing is to closely monitor the tires and wheel ends. Before driving, wrap around the car to check whether the tire pressure is uniform, whether there are any nails, bulges, or cracks on the tire surface. At the same time, check whether the wheel rim bolts are loose and whether the wheel hub temperature is abnormal. If the tire pressure is too high, it is easy to blow out the tire. If the tire pressure is too low, it will accelerate wear and increase fuel consumption. Under long-term heavy load, if there is a lack of oil at the wheel end, the bearing will overheat and lock up. After each long-distance run, you can simply touch the wheel hub temperature and promptly repair if there is abnormal heating. The second key point is to inspect the brake and air system. The risk of trailer brake failure is high. It is necessary to check whether the air pipe joint is aging, leaking, bulging, or cracking, test whether the brake returns smoothly, and regularly check the degree of brake pad wear. ABS line joints should avoid water ingress and corrosion. Many drivers only discover brake deviation or weak braking after getting on the road, mostly caused by air leakage or brake component jamming. In dusty and rainy areas, water accumulation in the air circuit can accelerate valve damage. Remember to drain the water on time. Thirdly, pay attention to the traction connection and support legs. The traction pin and traction lock buckle must be confirmed to be locked in place, and the connection position should be regularly lubricated with butter to avoid increased wear and clearance, and to prevent tail shaking during high-speed driving. The lifting and lowering of the support legs should be smooth, and gears that lack lubrication are prone to tooth breakage. When parking the trailer, try to use the support legs to bear the force, and do not rely on the tires for a long time to prevent deformation of the frame. The fourth check is the suspension, frame, and fixed position of the cargo. Leaf springs, bushings, and balance beams are large load-bearing components that are prone to wear and tear on bushings and cracking of welds when driving on bumpy roads. Pay attention to any abnormal noises or misalignment in daily life. After loading, tighten the straps and locks tightly. If the cargo deviates, it will cause uneven force on the trailer, leading to the risk of uneven wear and overturning. Reflective signs, taillights, and clearance lights should also be inspected. Cross border driving lights that are not up to standard may face punishment. Trailer maintenance does not have a high threshold, the key is persistence. There is no need to wait for faults to occur before repairing. Integrating several basic inspections into the process of driving and receiving the vehicle, timely handling of small problems can not only ensure the safety of drivers, but also extend the service life of trailers, making cross-border long-distance freight transportation more stable and worry free.
