In the 1980s, an elementary school teacher in a certain place made a question: Who is our worst enemy? The students replied: walking the tractor. In the early period of reform and opening up, the hand-held tractors thrived, and the overbearing in towns and villages endangered the safety of life and property of the people, so the above answers were available. If the same question is given to the citizens of Guangzhou, many people's answers are dump trucks.
Late in the night, in Guangzhou, there was always a puddle car that could not be seen passing by. Pedestrian cars couldn't avoid it, and each car was greatly overloaded. Traffic accidents caused by dump trucks were often reported. In order to completely solve the "difficulty" of dump trucks, a few days ago, led by the Guangdong Municipal Urban Management Committee, Guangdong Quality Supervision Bureau, the Public Security Traffic Police Detachment, the Committee and other departments jointly completed the "building waste transport vehicle load and sign and monitoring terminal "Specifications for carriage specifications and containment" (hereinafter referred to as "technical specifications") were approved by experts and passed. This means that the original dump truck that everyone talks about will change with us.
In the latest "Technical Regulations", except that the capacity of the newly admitted dump trucks must not exceed 12.2 cubic meters, the hoisting and lid opening and closing records function, speeding alarm and lid unclosed alarm function are required. Cargo status detection function, self-test and fault alarm function, data storage and transmission functions, and vandal prevention function. Additional auxiliary brake devices such as retarders must also be installed. The author believes that the installation of a retarder on the dump truck will greatly enhance the safety performance of the vehicle and help the dump truck get rid of the “killer on the roadâ€.
In fact, 80% of foreign heavy-duty trucks are equipped with retarders. As early as the 1950s, European and American developed countries have required large trucks with more than 8 tons to force the installation of retarder. Currently, retarders have become a bus in many European and American developed countries. Standard configuration for buses, coaches, medium and heavy goods vehicles. China has also issued a new standard for the "Regulations on the Operational Safety of Motor Vehicles", GB7258. The new standard stipulates: "Trucks and dangerous goods carriers exceeding 12 tons will be forced to install retarders or other auxiliary braking devices." The improvement of the access threshold for dump trucks in Guangdong is a beneficial addition to GB7258, and it is bound to accelerate the speed of popularization of retarders in the field of heavy trucks in China.
It is understood that in order to help China's heavy-duty users understand the retarder, an efficient auxiliary brake product as soon as possible, Tai Lema Automotive Braking System (Shanghai) Co., Ltd. has made many beneficial attempts. The Mercedes ACTROS3343 truck of Master Li of Menglian County, Yunnan Province, installed the Tellomar retarder with a maximum torque of 3300N/m. After using it, Master Li felt very deep. The main vehicle braking system does not need to use the original tank spray method to cool the water. The inspection of brake drums from Kunming to Simao can be done by hand. The temperature is quite low; the service life of brake pads is extended, and now the car has traveled 50,000 kilometers. The brake pads are in good condition and it is estimated that the brakes can be driven to 300,000 kilometers without replacement; the main brake is not used for deceleration, and the main brake can be used to exert the maximum braking force in an emergency. Can easily control the speed of the vehicle; after a set of auxiliary brake systems, the driving car will feel more at ease, increase the safety while the transport efficiency has been greatly improved, ordinary vehicles can only run about 3 months a month This car can run to 5-6 per month.
It can be seen that installing the retarder not only can effectively reduce security risks, but also brings real economic benefits to the user. For a dump truck that used to be a “street killer,†a retarder is undoubtedly a good medicine to save its water and fire.
