The necessary summer semi-trailer maintenance strategy for old drivers!

Summer is here, it's safe for trailer drivers! Check everything before driving before you hit the road. According to the needs of the driver's master, the editor now summarizes the summer semi-trailer maintenance strategy for the reference of the trailer driver's master: Xufeng Trailer

look at tires

Visually check the tire pressure, and visually check that there is no lack of air or debris attached, and then check whether the steel rim is deformed or cracked.

Check the tightness of the tire screws

Don't be too troublesome about the details of tightening the screw with the air gun. You should check each screw one by one to see if it is fastened. It is a trivial matter to lose a screw on the way. It can also be solved by money, but if you run into an accident It's a shame to come. To use a sentence is "tire is no small matter", I hope everyone remembers.

Just look at the suspension system

Which car is better

Look at the tightness of all nuts, bolts, and U-bolts, which are all related to tire eating.

Shake the outriggers to ensure normal

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

Feel the wear of moving parts

Check the box board, lock lever, reach out and touch the box board hinges, box hooks, stakes, container locks and other small parts to see if there is any crack or breakage.

Check all fixtures and reflective cursors pasted

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

Check out the tractor and semi-trailer brake connections

On the dashboard of the cab, after starting the car, see if the pressure gauge is enough, and then give the brakes to try the brakes.

Check the brakes for leaks

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