Truck and trailer tips - How to maintain your truck and semi trailer?
A customer in Ghana bought our flatbed semi trailer
1. Before the new trailer is used for the first time, we should check it according to the "instructions for use" and tighten all external bolts and nuts.
2. Within the first 300 kilometers of a new trailer, its components are in a running state. During this period, the weight of the trailer should not exceed 80% of the rated load, and it should not be driven on muddy roads.
3. After the new trailer runs for 30-50 kilometers, check the wheels and suspension bearings for high heat or noise. If you find any abnormality, find out the cause in time and remove it.
4. After the new trailer travels 300-500 kilometers, you should tighten all bolts and nuts.
5. For the use and maintenance of diesel engines and high pressure oil pumps, please refer to the instructions of the supporting parts.
1. Clean and lubricate according to all parts on the lubrication chart.
2. Check and adjust the gap between the tellurium discs and the brake hub of all wheels.
3. Check the brake system and hydraulic system for leaks and whether the connecting hoses are intact.
4. Inspect the electrical wiring for looseness, damage, or poor insulation.
5. Check the traction frame, bogie parts are intact.
6. Check whether the steering rod joint is loose and whether it affects the linearity of the tire. If necessary, adjust the steering rod system.
7. Check whether the suspension parts are intact.
8. Check all tires for excessive or abnormal wear, whether the tire pressure is sufficient, and whether the valve seats are correct.
9. Thoroughly clean the oil and dirt on all parts of the trailer, and check all parts for paint peeling and rust.
10. Inspect all parts of the power unit, clean the fuel tank and valves and check the oil quality, and change the oil if necessary.
1. Repeat the tasks of "Maintenance every 1200 kilometers".
2. Clean the hub bearings, fill with new oil and adjust the bearing problems.
3. The tire is transposed.
1. Repeat the tasks of "maintenance every 2,000 kilometers".
2. Remove the hub, clean or replace the damaged or worn parts and the hub bearing.
3. Replace the oil cylinder seals and damaged or worn parts.
4. The hydraulic pipeline is drained and cleaned. This work should be performed at least once a year.
5. Clean the suspension shaft and its bearings, and replace with new grease.
6. Clean the brake tellurium and brake tellurium disc shaft, drop 1-2 drops of oil on the brake tellurium disc shaft, and check and adjust the brake clearance.
In addition to observing the contents of the pre vehicle inspection, it must also perform the following maintenance.
1. For high pressure winding hoses in brake hoses and hydraulic systems, we must check whether the two types of hoses are subject to friction, pressure, etc. During the lifting and turning of the cargo platform, especially when the cargo platform is lifting or turning. We must perform the above inspections on the trailer after each shipment, and when found, we must immediately relocate and fix the hoses.
2. For brake hoses and hydraulic hoses, we must always check whether the rubber is aging, and immediately replace it when found.

The following safety inspections must be performed every week or before each shipment (whichever occurs first):
1. Check the tire pressure and adjust it to the level recommended by the tire manufacturer;
2. Check the tightness of the tire screws;
3. Check whether there is air leakage in the braking system and test whether it can be braked;
4. Check the tightness of all nuts, screws, and bolts that are suspended;
5. Check the brake connection of the tractor and semi-trailer;
6. Drain the air cylinder and the air chamber equipped with air suspension;
7. Check all the lamps and lanterns;
8. Check and ensure that the outriggers are working properly;
9. Check the wear of the moving parts.
1. Check the tightness of all suspension components (according to the torque data provided)
2. Check whether there are any breaks in the leaf spring reeds;
3. Check all brake system joints and hoses for damage and hose clips are missing;
4. Check the proper operation of relay valves and other valves;
5. Check the wear of the sleeve of the tension rod;
6. Check the brake drum for cracks or abnormal wear;
7. Check whether the lubricating oil of the axle will leak;
8. Check all fasteners, focusing on the fasteners used for legs, tires, axles, etc. (in any case, nuts, screws and other fasteners should be tightened to the recommended torque parameters);
9. Check the wear of the pull pin;
10. Check whether the brakes are normal;
11. Lubricate the outriggers and the traction plate / traction pin;
12. Check whether there is any open glue at the joints of the side wall panels, door panels and roof panels;
13. Replace worn parts with manufactured or approved parts.
After the vehicle has been in use for 6 months, a comprehensive inspection is performed every 12 months to ensure the performance of the vehicle (including maintenance at the 6th month). The inspection scope is the same as the monthly inspection mentioned above, with the following additional provisions:
1. Remove the brake drum and thoroughly check that the brake shoes have no additional or improper wear;
2. Check the brake shoe return spring, brake bushing, camshaft sleeve, brake shoe drum, etc. for damage;
3. Check the bearing and axle connecting parts;
4. Thoroughly inspect the structure of the vehicle and report it immediately if there is a problem;
5. Replace all worn or damaged parts with replacement parts recommended by TITAN Vehicle.
In order to drive safely and extend the service life of semi-trailers, it is necessary to regularly replenish grease to each lubricating part. Pay attention to the following when replenishing grease:
1. Clean the refueling utensils and oil cups first.
2. When the oil cup cannot be filled with grease, the cause should be checked, and if it is damaged, it should be replaced.
