China's construction of concrete mixers for the first time equipped with retarder
In the past, concrete mixers in our country did not come equipped with retarders. However, this is about to change. Recently, Shenzhen Terjia Technology Co., Ltd. successfully tested its M7-35 eddy current retarder on a concrete mixer produced by Sany Heavy Industry Group. The results were impressive, with the retarder demonstrating excellent braking performance and significantly improving safety during downhill driving. This marks a milestone, as it is the first time that a local concrete mixer has been fitted with an eddy current retarder.
According to a project manager from Sany Heavy Industry Group, the frequent and prolonged braking required by concrete mixer trucks—especially under heavy loads—often leads to brake failure. Additionally, these vehicles typically operate in challenging road conditions, which demands extra caution from drivers. Historically, factors such as cost and limited awareness made it uncommon to install retarders on local mixers.
However, the M7-35 eddy current retarder, developed specifically for heavy-duty vehicles over 30 tons, offers a practical solution. As reported by Terjia’s representative, the device not only enhances vehicle safety but also reduces the physical strain on drivers, making long trips more manageable and safer.
This development represents a significant step forward in improving the efficiency and safety of construction equipment. With growing emphasis on driver well-being and operational reliability, the adoption of advanced technologies like eddy current retarders is expected to become more widespread in the coming years.
