1、Brake system malfunction
Brake system failure is one of the common faults in semi-trailers, mainly manifested as brake failure or reduced braking force. At this point, it is necessary to check the brake circuit for damage, brake pad wear, and brake cylinder operation in a timely manner, and replace accessories if necessary.
2、Bearing failure
Semi trailers that frequently transport heavy objects are also prone to bearing problems, mainly manifested as increased noise or severe shaking. The solution is to replace the damaged bearings or reassemble the entire bearing components.
3、Electrical system malfunction
The electrical system of a semi-trailer mainly includes the light system, power supply system, etc., which are also common places where faults occur. The fault manifests as the car lights not turning on or the power supply being unstable. At this time, it is necessary to check whether the car light circuit is damaged, whether the power system is normal, and replace the circuit and power system components if necessary.
4、Air pressure system malfunction
The air pressure system of a semi-trailer mainly includes the braking air circuit, suspension air circuit, air pressure gauge, etc. When the air pressure system malfunctions, it can lead to brake failure or unstable suspension. Learning to use a pressure gauge correctly, checking and replacing damaged components in a timely manner, can reduce the occurrence of pressure system failures.
5、Chassis malfunction
The chassis is the main part of a semi-trailer, and over time, it may experience fatigue damage, corrosion, and other issues, mainly manifested as unstable suspension or unstable vehicle stability. Timely inspection of chassis components and replacement of damaged parts can prevent chassis malfunctions from occurring.
