Summer is here, and for trailer drivers, safety comes first! Only after checking that everything is OK before driving can you hit the road. Based on the needs of the driver masters, the editor has now summarized a comprehensive guide to summer semi-trailer maintenance for the reference of trailer master masters:
Look at the tires
Visually check the tire pressure to see if there is no lack of air or debris attached, and then check whether the steel rims are deformed, cracked, etc.
Check the tightness of tire screws
Don’t bother with the details of tightening the screws with the wind cannon. You should check each screw one by one to see if it is tight. A screw missing halfway is a trivial matter, and a tire missing can be solved with money, but if there is an accident, you will regret it. Out of reach. To paraphrase a sentence, "tires are no small matter", I hope everyone will remember this.
Just take a look at the suspension system.
Check the tightness of all nuts, bolts, and U-bolts. This is all related to whether the tire will be damaged.
Shake the legs to make sure they are normal
When inspecting the outriggers, be sure to shake them up and down a few times to see if there are any cracks in the welding joints. Especially for those who are now racing and driving, they must pay attention to this problem.
Feel for wear and tear on moving parts
Check the box board, lock rod, reach out and touch the box board hinges, box hooks, stakes, container locks and other small parts to see if there are any cracks or breaks.
Check all light fixtures and reflective stickers
Just check the electrical circuit and see if there is any abnormality. Get in the car and turn on the lights to see if there are any broken lights and whether the reflective signs are missing. I believe there must be drivers who have been fined for missing reflective signs on the road.
Take a look at tractor and semi-trailer brake connections
On the dashboard of the cab, after starting the car, check whether the air pressure gauge is sufficient, and then apply the brake to see if it is sufficient.
Listen for brake leaks
Get out of the car and listen to see if there is any sound of air leakage, and test whether the brakes are working properly.
