1、 Improper operation by the driver. Why is it that the driver did not operate properly? Mixer is a special vehicle, which has a history of more than ten years in China. Most drivers are novices in driving mixer. Many drivers have been driving trucks for more than ten years, but driving cement mixers is a novice. Concrete mixer truck is different from ordinary truck, because the cement mixing tank rotates constantly during driving. If you don't control the speed and the speed of the tank when turning or the road is bad, it's easy to overturn. This has nothing to do with the quality of the car.
2、 Bad road conditions. Many cement mixers are used on construction sites, and the road conditions on some construction sites are particularly bad. Last time I heard a customer say that more than 1m stones were piled on the ground of a construction site. In some places, the speed was slow, it was easy to sink the car in, and we had to rush through it quickly.
The concrete mixer itself is a low-speed vehicle. If you encounter such a project, you'd rather not take such a job. Before long, the car turns over and loses a lot.
3、 How to avoid rollover. When the cement mixer truck is overloaded, it must be noted that the engine speed is within the range of 1000-1400 rpm to make the engine have the maximum torque. During the transportation of concrete, the speed shall not exceed 40km / h to ensure driving safety. When turning, be sure to slow down on the straight road before turning. (most rollovers occur when turning) when the mixer transports the mixed concrete, the speed of the mixing drum is 2-10 R / min.
During transportation, the rotating speed of the mixing drum on a flat road shall be 2-3 rpm. When driving on a road with a roll gradient greater than 50 or a road with large shaking left and right, the mixing rotation shall be stopped and resumed after the road conditions improve.
