Semi trailer maintenance matters

　　1. Look at the tires　　Visually check the tire pressure to see if there is any lack of air or debris adhering, and then check for deformation, cracks, and other phenomena on the steel rim.　　2. Check the tightness of the semi-trailer tire screws　　Tighten the screws of the wind cannon. Don't be too troublesome about this detail. You should check each screw one by one to see if it is tight. Running a screw halfway is a small matter, and losing a tire can also be solved with money. However, if an accident occurs, it will be regrettable. To put it simply, "Tires are nothing small." Please remember.　　3. Just take a look at the suspension system　　Check the tightness of all nuts, bolts, and U-bolts, as this is related to whether the tire is being worn.　　4. Shake the legs to ensure normal operation　　The inspection of the supporting legs must be done by shaking and dropping them a few times, and then checking for any cracks in the welding area, especially for those who are currently running, swinging, and hanging. It is important to pay attention to this issue.　　5. Touching the wear and tear of moving parts　　Check the box board, lock rod, reach out and touch the box board hinges, hooks, stakes, container locks and other small components to see if there are any cracks or breakage.　　6. Check all lighting fixtures and reverse cursor pasting　　Check the electrical circuit and feel for any abnormalities. When getting on the car, turn on the lights to see if there are any broken lights and if the reflective signs are missing. It is believed that some cardholders have been fined for missing reflective signs on the road.　　7. Check the braking connections of the tractor and semi-trailer　　On the dashboard in the driver's cab, check if the air pressure gauge is sufficient after starting the car, and then apply the brake pedal to test the brakes.　　8. Listen for any air leaks in the brakes　　Get off the car and listen for any sound of air leakage, test if the brakes are working properly.

What are the reasons for the abnormal increase in fuel consumption of semi-trailers?

　　What are the factors that affect the fuel consumption of semi-trailers? The engine horsepower, cargo capacity, road conditions, driver's driving skills, and the condition of the semi-trailer are all related.　　The horsepower of the semi-trailer front end varies, and the fuel consumption also varies. For example, tractor brands such as Ouman, Shaanxi Automobile, and Steyr have different engines, resulting in different fuel consumption. The cargo capacity is also closely related to fuel consumption, and the heavier the weight, the higher the fuel consumption. But if there is an abnormal increase in fuel consumption, it is necessary to thoroughly investigate the cause.　　1. Tire pressure issue. Regularly check the tire pressure of the semi-trailer to see if it meets the air pressure standards. Generally speaking, insufficient tire pressure will increase fuel consumption.　　2. Tire wear. Regularly check the wear of semi-trailer tires. If the tires of the semi-trailer are severely worn, slippage may occur frequently, increasing fuel consumption.　　3. Check the bearings and brake system. Regularly inspect the semi trailer bearings and brake system for any malfunctions. If the wheels rotate abnormally, it will affect the vehicle speed and increase fuel consumption.
