Container transport trailers require quick inspections of critical components before and after every trip. These checks cover the connection between the kingpin and the fifth wheel, tire wear and inflation pressure, potential air leaks in the braking system, and the proper functioning of lighting and electrical systems. Special attention must also be paid to the container locking mechanisms to ensure they are neither loose nor deformed, thereby preventing safety hazards during transport.
Systematic maintenance should be performed regularly on the braking system, suspension system, and axles. For the braking system, accumulated water in the air reservoirs must be drained periodically, and brake pads should be inspected for wear and replaced promptly. Suspension components-whether leaf springs or air suspension systems-require checks for cracks, air leaks, or deformation. Bearings should be lubricated at scheduled intervals to minimize operational wear and extend service life. These maintenance tasks are typically carried out according to standardized schedules based on mileage or duration of use.
Anti-corrosion care for the chassis and maintenance of the overall structure are equally important. Prolonged use can lead to rust on the trailer's surface caused by friction, rain, or exposure to salt spray; regular cleaning, touch-up painting, or anti-corrosion treatments are necessary to preserve structural integrity. For trailers that remain parked for extended periods, rust-prevention measures should be implemented, and the trailer should be moved periodically while unloaded to prevent tire deformation and component seizure. Systematic and periodic maintenance significantly enhances both the safety and the service life of the trailer.
