Maintenance of Trailers 1. Daily maintenance (1) After each operation, the trailer body and chassis should be cleaned in a timely manner. (2) Check if all safety devices and light pens are reliable.

(4) Check the inflation condition of the tires and inflate them according to regulations, with an error not exceeding ± 0.5kg/cm ². In addition, check the tightness of the nuts on each wheel.

2. Trailers should undergo the following maintenance every 600 to 800 kilometers traveled: (1) Check the steel plate springs, bushings, and pins. If the wear of the steel plate spring pin exceeds 1.5mm, the gap between the pin and the bushing is too large and should be replaced.

When driving a trailer for 3000-4000 kilometers, in addition to the above maintenance, the following maintenance should also be carried out: (1) Clean and adjust the hub bearings, and add lubricating grease; Clean and inspect the wear of the spring steel plate, and make necessary repairs or replacements; To adjust the bearing clearance, first tighten the adjusting nut to the end, then retract it by 1/6 turn, and then tighten it.
