What should the semi-trailer pay attention to during the running-in period?

First of all, the semi-trailer should do a systematic test during the running-in period to see whether the connection with the host is correct and safe and reliable, check whether there is any problem with the braking system, whether the tire pressure of the semi-trailer meets the standard, and check whether the various parts of the semi-trailer are loose, cracked and deformed.

Subsequently, the load of the semi-trailer during the running-in period cannot exceed 80% of the rated load weight; During medium-speed driving, pay attention to the temperature of bearings and hubs. After driving about 40 kilometers, fasteners such as leaf springs and wheels are tightened once, and they can be started normally after three tightenings.

Then, during the trailer driving, carefully check whether the brake is hot, whether there is an abnormal smell, whether the trailer running device is offset, etc., if there is any abnormal phenomenon, stop to check and exclude.

Fourth, when loading sharp and heavy items, you need to pay attention to avoid damage to the carriage body.

Fifth, you need to pay attention to smooth driving, predict the braking distance in advance, and try to avoid emergency stops.

Sixth, regularly check the tire bearing clearance. When checking, lift the carriage and turn the wheels to see if there is any noticeable shaking; If there is significant shaking, adjust it.
