The industry standard "Dump Semitrailer" was formally drafted, and the industry will be further standardized.

October 18, 2022

Recently,In order to standardize the design and production of dump semi-trailer in China,Improve the performance, quality and safety level of dump semi-trailer products,Meet the needs of production enterprises and transportation services,Perfecting the Trailer Standard System,Highway Science Research Institute of the Ministry of Transport、Shandong Changlong Automobile Manufacturing Co., Ltd.,Anhui Huaxing Vehicle Co., Ltd.、Henan Juntong Vehicle Co., Ltd.、Yangzhou CIMC Tonghua Special Vehicle Co., Ltd.、Tongya Automobile Manufacturing Co., Ltd.、Hayward Machinery(China)The first standard drafting meeting was held in Mengyin, Shandong Province.。

It is reported that,《Dump semi-trailer》The first standard drafting meeting mainly discussed《Dump semi-trailer》Standard drafting principles、Standard framework and main technical contents of the standard,Formed a more mature、Draft of the refined standard,It also clarifies the main work contents and division of labor in the next step.。

Purpose of standard drafting

For the last two years,With the rapid development of dump semi-trailer in China and the sharp increase in the number of dump semi-trailer.,Production of dump semi-trailer in China、Used earlier though,However, the production and sales volume is low.、The product quality is not high.、Not widely used。There is no uniform product standard in the industry as a support.,Safety accidents and quality disputes caused by various reasons continue.。

So,Form a stable、Widely used industry standard for dump semi-trailer,Design of Self-discharging Semi-trailer in China、Production and manufacturing,And that product quality is improve,The safety of the dump semi-trailer under various operation States can be realized,Achieve security、Efficient transportation,It is of great significance to promote the healthy development of related industries.。

Principles of standard revision

The technical unit of this standard is the National Automobile Standardization Technical Committee.(SAC/TC114),Recommended Automotive Industry Standard,It belongs to the product standard。It's from vehicle performance.、Start with configuration,The invention solves the problems of the design and the application of the dump semi-trailer,、Manufacture、Outstanding problems in the process of testing.,Ensure the specification design of the dump semi-trailer、Manufacture、Tests, etc,Safe、Environmental protection、Energy-efficient operation。In order to make the standard consistent with domestic standards,、Consistency and coordination of laws and regulations,At the same time, raise the dump semi-trailer.

Vehicle configuration performance and standardization,The principles for the revision of the standard are defined as follows::

One is to make the standards formulated consistent and coordinated.,That is to say, when drafting the standard, we should combine the relevant countries that have been revised in recent years.、Technical contents of industry standards and relevant management requirements of the industry,It can not produce cross and contradiction;

The second is to make the standard forward-looking.,When determining standard specifications,It should be advanced in the country or industry.,Through several years of implementation, it does not lag behind the actual indicators of the industry.;

The third is to make the standard operable and implementable.,Since the revised standard is the industry standard available to manufacturing enterprises,,In terms of standard content, it is more important to reflect the convenience of standard use.,And relevant technical requirement and tests can be realize.;
The four is to combine the security of our country.、Environmental protection、Requirements for energy conservation,The technical content of the standard shall refer to the relevant requirements of the country.,Combined with international standards, this standard has the level of internationalization and universality.。

Main contents of the standard

Dump semi-trailer is a special vehicle which combines dump function with general freight semi-trailer.。The carriage carrying the goods can automatically turn over at a certain angle for unloading.,Thereby saving the unloading time and labor force.,Shorten the transportation cycle,And that production efficiency is improve,Reduce transportation costs and many other comprehensive advantages.。

The standard drafting project team is based on the above principles.,Research work on standard formulation and drafting。The standard specifies the technical requirements for dump semi-trailers.、Inspection method、Inspection rules、Identification、Onboard documents、Transportation, storage and delivery requirements;This standard applies to dump semi-trailers used on roads.。

The main contents of the standard are as follows::Range、Normative references、Terms and definitions、Technical requirements、Test method、Inspection rules、Identification、Onboard documents、Seven chapters of transportation, storage and delivery requirements。

Among,Technical requirements are one of the core contents of the standard.,In order to facilitate the understanding and mastery of the technical requirements of this standard,,This chapter is composed according to the structure of dump semi-trailer.、Manufacturing process and main performance are divided into complete vehicles、Frame、Carriage、Hydraulic system、Preparation of processing technology and others。Which provides that,The dump semi-trailer shall be manufactured in accordance with the drawings and technical documents approved by the specified procedures.;Overall dimensions of dump semi-trailer、Axle load and mass limits and associated operational safety requirements shall be metGB 1589、GB 7258 andJT/T 1178.2 requirements, etc.。

Dump semi-trailer is a special vehicle that combines dump function with general freight semi-trailer.,It has many advantages,Therefore, the industry standard is formulated.,It has a positive significance for the standardized development of the industry.。
