1. Vehicle maintenance specification2. Weekly or routine inspection before each transportation (operated by the user) The following safety inspections must be carried out every week or before each transportation:A Check the tyre pressure and adjust it to the level recommended by the tyre manufacturer;B Check the tightness of tire screws;C Check the brake system for air leakage and test whether it can brake; D Check the tightness of all nuts, screws and bolts for suspension; E Check the braking connection of tractor and semi-trailer; F Drain the air reservoir and a

First of all, the semi-trailer should do a systematic test during the running-in period to see whether the connection with the host is correct and safe and reliable, check whether there is any problem with the braking system, whether the tire pressure of the semi-trailer meets the standard, and check whether the various parts of the semi-trailer are loose, cracked and deformed.Subsequently, the load of the semi-trailer during the running-in period cannot exceed 80% of the rated load weight; During medium-speed driving, pay attention to the temperature of bearings and hubs.

When there is an electrical fault in the oil tank trailer, it is an important prerequisite for maintenance to quickly and accurately judge the fault. After a lot of practice and research for a long time, the maintenance engineers have realized that the following methods are very practical in electrical diagnosis.Observation methodIf the starter of the ofuel tanker trailer cannot be started, turn on the headlight first, observe its brightness, and judge whether the fault is caused by poor contact of the power line or battery power loss.

Everyone has different habits when driving, and generally adjusts their rearview mirrors based on their feelings. In fact, there are certain rules for rearview mirror adjustment. Attention should be paid to the following issues during adjustment: For interior rear-view mirrors, adjust the left and right positions so that the left edge of the mirror surface is just cut to the right earline of your image in the mirror.

1. ChassisThe frame is mainly composed of girder - welded I-beam, support beam, connection beam, side beam, lock, traction pin connection device, panel, etc.The side beams are generally channel steel or bending pieces. At present, most trailers use channel steel. There will be more side beams for bending pieces with light body, because the requirements for strength are not too large.The supporting beam is the crossing beam, and now most of them are W beams. 2.  Upper bodyFor side wall trailers, the bodywork part refers to railings, gantries, etc.

Fence semi trailer is a relatively common means of cargo transportation, with a wide range of types and uses.According to the regulations, the height of the fence truck trailer shall not exceed 4.2 meters. According to the regulations, the loading height of heavy and medium-sized trucks and semi-trailers shall not exceed 4 meters from the ground, and the vehicle carrying containers shall not exceed 4.2 meters. Semi trailers are mostly 3 axles trailers, which are connected with semi-trailers through front traction pins.

1. Early wear of the central part of the tire.The main reason is that the tire inflation volume is too large, which not only affects the shock absorption performance of the tire, but also causes excessive deformation of the tire.2. Both sides of the tire are worn too much.The main reason: insufficient inflation of the tire or long-term overload driving, so that the contact surface between the tire and the ground is large, causing the two sides of the tire to contact the ground and form early wear.3.

Here are the basic steps to adjust brakes on a semi trailer:First, park the trailer on a level surface and chock the wheels to prevent movement.Remove the dust cap from the brake drum.Use a brake adjusting tool to reach inside the drum and turn the adjusting star wheel in a clockwise direction to tighten the brake shoes against the drum.Tighten the shoes until you feel resistance from the brake drum.Then, turn the star wheel back 10-15 times counterclockwise to provide proper clearance between the brake shoes and the drum.Put the dust cap back on the brake drum to protect it from debris and mo

The length of a semi-trailer can vary depending on the specific model, configuration, and applicable regulations. However, in most cases, the length of a semi-trailer ranges from 48 to 53 feet (14.6 to 16.2 meters). These trailers typically have a cargo box that is about 8-8.5 feet (2.4-2.6 meters) in width and 8-9 feet (2.4-2.7 meters) in height.
