The most important thing for semi-trailers in summer is the rainy season, in addition to the problem of side slip and having good driving habits and skills. Brake and tire maintenance are also driving safety. There is a lot of rain in summer, so pay attention to the paint on the exterior of the car. The acidic components in rainwater can easily corrode the car paint, and the body can be waxed and sealed. Chassis is rustproof. The chassis is the closest to the ground and is easy to corrode. Therefore, we must pay attention to the cleaning and anti-rust treatment of the chassis.

Brake fluid; The most fear of brake failure when driving, the brake is the most critical part of the car. One of the guarantees for our safe driving, the life of brake fluid is generally two years. We should change the brake fluid at the appropriate time. When changing the brake fluid, be sure to drain the old brake fluid and replace it with a new one, so as not to mix the old and the new. After changing it, try the brakes on both feet in an open field. Let the air in the oil out.
The possible reason for the burnout of the gearbox is; lubrication failure, the gear is not lubricated. It burns when it gets high temperature. There is also the symptom of burning the gearbox if the gear is stuck. Therefore, the transmission oil must also be added carefully. The same is true for steering wheel oil. Sometimes, you will feel that the steering wheel is very heavy. It is best to use semi-synthetic oil.

In the rainy season, pay attention to the wiring of the car, or the intrusion of rainwater. Before driving, be sure to check the car to see if it is normal. Especially car tires, car tires are the most important part, especially the tire on the steering wheel

Whether it is an all-aluminum semi-trailer or a warehouse-type semi-trailer, the engine occupies a dominant position in all large trucks and semi-trailer vehicle parts, so how do drivers and friends usually maintain the engine of the semi-trailer?

Maintenance

Safe driving is the top priority in the trucking career. To prevent problems, the trailer should be inspected on a weekly basis or before each transport. The more complete the inspection, the better.

1. Look at the tires and visually measure the tire pressure
Visually check that there is no lack of air and debris attached, and then look at whether the steel ring is deformed or cracked.

2. Check the tightness of the tire screws
Don't be too troublesome about the details of tightening the screws with the air gun. You should check each screw one by one to see if it is tight. It is a trivial matter to lose a screw on the way, and a tire can be solved with money, but if you run into an accident, you will regret it. Unreachable.

3. Just take a look at the suspension system
Look at the tightness of all nuts, bolts, and U-bolts, which are all related to tire eating.

4. Shake the outriggers to ensure normal
When checking the outrigger, you must shake it up and down a few times, and then check whether there are any cracks in the welding.

5. Touch the wear of moving parts
Check the box board, lock lever and touch the box board hinges, box hooks, stakes, container locks and other small parts to see if there is any crack or breakage.

6. Check all fixtures and reflective pastes
Check the electrical circuit to see if there is any abnormality. Get on the car and turn on the lights to see if there are any broken lights. The reflective signs are not missing. I believe there must be card friends who have been fined for missing reflective signs on the road.

7. Look at the brake connection of the tractor and semi-trailer
After starting the car on the cab dashboard, check if the pressure gauge is enough, and then give the brakes to try the brakes.

8. Listen to the brakes for air leakage
Get out of the car to hear if there is any sound of air leakage, and test whether the brakes work well.

Maintenance common sense

For the maintenance of the semi-trailer in summer, we must first pay attention to the problem of anti-skid driving in the rainy season. In addition to the driver's good driving habits and skills, the maintenance of brakes and tires is also the key to driving safety, so we must pay attention to maintenance in daily use. Maintenance can be carried out as follows.

(1) Body waxing and sealing glaze. The acidic components in rainwater are highly corrosive to automotive coatings. Therefore, in the rainy season, it is better to bring the beauty of the car surface.
(2) The chassis is rust-proof. In addition to paint, the chassis is close to the ground and is easy to corrode, so we must pay attention to the cleaning and anti-rust treatment of the vehicle chassis.
(3) Disinfection of trailers. Clean the interior of the vehicle in the rainy season to avoid the harm of various bacteria to the human body.
(4) Check the circuit in time. During the rainy season, the vehicle electrical system should be checked frequently to avoid leakage failures.
(5) Regular heating. Turn on the heater to bake mold. When the sun is shining, you can stop in the sun to be exposed to the sun and open the windows to allow air convection. Regular maintenance of the semi-trailer can effectively prolong the service life of the semi-trailer, which is necessary for safe driving.
