Semi-trailer maintenance knowledge in the rainy season

Semi-trailer maintenance in the rainy season is crucial to avoid faults caused by humidity and rainwater. Here are the key points:

1. Keep the chassis dry: Regularly check the chassis, axles and brake system to prevent rust and corrosion caused by rainwater immersion.
 

2. Check the brake system: Ensure the brake pads and brake fluid are normal, avoid water entering the brake system to prevent failure.
 

3. Protect electrical components: Wrap the wiring and connectors with waterproof tape to avoid short circuits caused by water ingress.
 

4. Inspect tires: Check tire pressure and tread depth regularly, as wet roads easily lead to skidding.
 

Proper maintenance in the rainy season can effectively extend the service life of the semi-trailer and ensure driving safety.
