Concrete mixer truck's new rules

• This year's initial, China vehicle service centers issued a "specification for concrete mixer truck of the announcement of the management requirements of the notice" requirement to curb unhealthy development of the concrete mixer truck market at present. In recent years, domestic manufacturers producing tank capacity is growing in volume, in today's market, the 6x4 chassis do 12 Parties have fairly widespread; 8x4 chassis has 16 or even more be done, the overload of the concrete mixer truck driving in the city every day, concrete tanks have increased the height of Center of gravity of the vehicle, truck rollover caused casualties of traffic accidents occur frequently.Various automobile manufacturers and testing bodies in order to further standardize the management of the announcement of concrete mixer truck, through research, and agreed to consult the Ministry of industrial policy Division, now the concrete mixer truck management requires notification of the announcement are as follows: 1. in the regulatory requirements, technical requirements for truck-mounted concrete mixer, add the following three points:(1) concrete mixer truck should conform to the requirements in the following table: two-axle tank car volume cannot be greater than 8, three-axle vehicle tank compartments shall not exceed 12 square, four-axle cars of tank volume cannot be greater than 16.(2) the concrete mixer truck's mixing drum fill rate should be not less than 51.5% (fill rate definition: mixing stirring volume and geometric volume ratio, expressed as a percentage). (3) the stirring capacity of concrete mixer truck shall meet the following requirements: stirring capacity Max load (kg)/density of the concrete (kg/m3) x110% Note: the concrete density recommended by GB/t 26408-2011 of the truck-mounted concrete mixer 2400kg/M3. 2. to declare the administrative requirements of parameters: (1) the original notice in the parameters bar of "volume" parameter is corrected to "stirring volume" parameter, stirring capacity according to the definition of the truck-mounted concrete mixer GB/T 26408-2011. (2) in record parameter in the increased tank body geometry capacity, and tank body installation dip parameter, and stirred capacity and tank body structure diagrams, diagrams content should including tank body size (as tank total length, and tank body maximum od, and into material mouth diameter,), and tank body material (refers to contact media of material, including aluminum, and stainless steel, and carbon steel, and non-metallic,), and tank body wall thick, and tank body stirred capacity calculation process. 3. starting from 269 batches of notices, should the relevant manufacturers and testing bodies in accordance with the requirements for reporting and testing of new products. 4. in the notice does not comply with the technical requirements of the relevant product, the relevant manufacturer should be on notice of the rectification before July 1, 2015, will suspend fails to meet the requirements of the product announcement.From the data listed in the table above you can clearly see that if the new rules were to be implemented, then mainstream large concrete mixer truck on the market today will be the end, overload will be contained. But the current situation of domestic policy measures on, want to truck mixer market back to norm, also takes a long time to remedy.
