Identification of the cause of the trailer fire

Trailer fire cause identification is a process in which qualified appraisers and institutions conduct scientific analysis and judgment on the cause of the fire in accordance with relevant standards and procedures after a trailer fire occurs. This identification usually covers a comprehensive inspection and analysis of the vehicle's structural systems such as mechanical systems, electrical systems, oil systems, and external factors to determine the cause of the fire.
The main causes of trailer fires may include, but are not limited to, brake system failures, wheel hub system problems, tire blowouts, etc. For example, a fault or improper adjustment of the braking system may cause the trailer to brake abnormally and generate high temperatures, causing a fire; if the wheel hub system is not maintained in time or is not standardized, it may cause a fire due to high temperatures due to friction; a flat tire may cause the tire to overheat and burn, which may also cause a fire in the trailer.
In the case of trailer fire cause identification, Zhongke Testing can provide trailer fire cause identification services.

A freight company was driving a newly purchased trailer to transport goods. When it entered the highway entrance, it suddenly caught fire, causing serious damage to the trailer and the goods it carried. It also damaged highway facilities and seriously affected traffic. After investigation, the fire brigade initially determined that the cause of the vehicle fire was spontaneous combustion. As a result, the trucking company sued the car company for compensation.
was entrusted by the court to conduct an appraisal and analysis of "whether there are quality problems" with the trailer involved.
identification and analysis results: The
identification and analysis expert group discussed and conducted comprehensive quality technical analysis on the relevant information and on-site investigation of the trailer involved in the case, and made the following suggestions and conclusions:
The design size deviation of the tires of the trailer involved in the case caused serious wear of the tire pads, causing a reduction in air pressure and damage to the wheels. Abnormal wheel transmission causes the tire rubber and steel wire to become entangled and accumulated between the dust cover and leaf spring, causing abnormal friction, generating high temperatures and causing fires.
