Recently，China Machinery Industry Federation and CNASMechanical Professional Committee/China Automobile and Motorcycle Inspection and Certification Alliance decided to carry out the research“Operating truck(Train)Interlaboratory comparison of steering stability”It's in full swing，Automobile testing institutions from all over the country carry out project competition at Xiangyang Automobile Test Site。

And in this laboratory comparison,，There is a 13-meter warehouse semi-trailer trailer, but it is particularly prominent.，It is from Shandong Changlong Automobile Manufacturing Co., Ltd.（Hereinafter referred to as Changlong Trailer）。

Semi-trailer as the only laboratory comparison test，Changlong trailer under full load is subjected to various tests of operating stability under extreme road conditions.，Excellent product quality has been highly recognized by engineers of many national automobile testing institutions.。

Test sample vehicle of national testing institution

This time“Operating truck(Train)Interlaboratory comparisons of handling and stability are conducted by China Machinery Industry Federation and CNASMechanical Professional Committee/In order to improve the technical ability of handling and stability test of various testing institutions in the automotive industry, China Automobile and Motorcycle Testing and Certification Alliance，Strengthen the process control of test and inspection quality，To ensure the effectiveness and consistency of the test results of the handling and stability test of operating vehicles.，All the participants in the laboratory comparison are national automobile quality inspection and inspection centers.。

As the quality of domestic automobile products,“Touchstone”，Each national automobile quality inspection center needs to complete the operation of trucks within the prescribed time.(Train)Comparison of two items of handling stability and gyroscope。

Among，Handling and stability mainly tests the rear amplification factor of lateral acceleration in lateral stability test.；Average yaw rate at base speed for hunting test。The gyroscope project mainly tests the roll angle.、Pitch Angle、 Yaw rate、Test of roll angular velocity, etc.。

Focus on high-performance semi-trailer for 35 years

In fact，This is not the first time that Changlong trailer has appeared on the stage of authoritative laboratory comparison as a competition vehicle.。

As early as October 27, 2022—The 29th，Changlong Trailer as“2022 Sichuan-Chongqing Road Freight Vehicle Driver Professional Skills Competition”The only designated race semi-trailer。

Why do Changlong trailers frequently board the designated vehicles in national and regional competitions?？The key is quality.。

Changlong Trailer is a member of the Trailer Sub-Standard Committee of the National Automobile Standardization Committee.，Focus on high-performance semi-trailer for 35 years，Since its inception，Changlong Trailer Industry First Launched Trailer“Customization Center”，By“Leader in China's Special Purpose Vehicle Industry”Sun Fusen, chairman of Changlong Trailer, personally led the way.。

“All these years，Changlong trailer goes all out，Repeatedly study the latest standards and regulations，United Universities、Scientific research institutes devote themselves to studying technology，Go deep into all kinds of bad working conditions，Listen to the opinions of card friends，Continuous targeted improvement of the vehicles produced，Better solve the problem of short service life of the semi-trailer、Cracking、Brake failure and other problems。”Sun Fusen, chairman of Changlong Trailer, said.，Changlong trailer“Customization Center”It can tailor a more suitable trailer for card friends.，So that customers can use peace of mind，Buy at ease。This time, it has become the only designated trailer for laboratory comparison by the national testing agency.，It is not only highly recognized by the relevant state authorities in the field of Changlong deep ploughing trailer customization.，It is also the trust of Changlong trailer focusing on high efficiency semi-trailer for 35 years.。
