Daily Inspection Items for Semi-trailer
Safe driving is of utmost importance in the career of semi-trailers. To prevent any potential accidents, routine checks should be conducted before each week or each transport. The more items checked, the better. Below, Ultraton will guide you through eight major aspects to help supplement and improve your pre-driving inspection.
Start by examining the semi-trailer's tires
Check tire pressure: visually inspect for any signs of lack of air or debris, and look for any deformation or cracks in the steel rims.
Next, check the tightness of the semi-trailer tire screws
Secure valve screws: do not overlook this detail. Check each screw one by one for tightness. Losing a screw on the road may seem like a small matter, and losing a tire can be solved with money, but if an accident occurs, it will be too late to regret. As the saying goes, "there is no small matter when it comes to tires."
Look at the semi-trailer's suspension system
Check the tightness of all nuts, bolts, and U-bolts, as they all affect tire wear.
Ensure that the semi-trailer's stabilizer legs are functioning normally
When checking the legs, be sure to shake them a few times to ensure they are stable, and check for cracks in the welding area. Especially for those friends who run with loose trailers, please pay attention to this issue.
Check the wear of the semi-trailer's moving parts
Check the box plate, lock rods: Reach out and touch the small parts such as the hinge, container hook, plug connection and container locks to see if there are any cracks or damage.
Check all of the lights and reflector stickers on the semi-trailer
Observe and feel for abnormalities. Turn on the lights and check for any broken ones, and check to see if the reflectors are missing. We believe that there are certainly friends who have been fined for missing reflectors while on the road.
Look at the braking connection between the tractor and the semi-trailer
After starting the car, check if the air pressure is sufficient, and then press on the brakes to see if they are working properly.
Listen for air leaks from the semi-trailer's braking system
Listen for any signs of air leaks while getting out of the car, and test to see if the brakes work.
Only travel after confirming that everything is okay. Personal safety is paramount, and Ultraton sincerely hopes that all friends have a safe journey.
