1. The first thing is to adjust the center rearview mirror. Adjust the left and right position of the cab to the left edge of the mirror and cut it to the right ear of the image in the mirror. This means that in general, you can't see yourself from the central rearview mirror, but the upper and lower positions are to place the distant horizon in the center of the mirror.
2. Adjust the left rear-view mirror. When processing the upper and lower positions, place the far ground line in the center, and adjust the left and right positions until the car body occupies 1 / 4 of the mirror area
3. Adjust the rear rearview mirror. Because the driver's seat is on the left side, it is not easy for the driver to master the situation on the right side of the vehicle. In addition, when adjusting the up and down positions of the right side rear-view mirror, the ground area should be larger, accounting for about 2 / 3 of the mirror surface. As for the left and right positions, the car body should also be adjusted to account for 1 / 4 of the mirror area.
4. Since the loading mixer, how to eliminate the dead angle of sight as far as possible, many people think that to eliminate the blind angle of sight, they should try to adjust the left and right rear-view mirrors outward or downward. In addition, studies have shown that many people have to adjust the central rearview mirror to see themselves. In fact, this is a wrong practice. Under normal circumstances. When the driver only turns his eyes without turning back, he can see about 200 degrees left and right in front of him. In other words, he can not see about 160 degrees. In fact, the left and right rear-view mirrors, together with the central rear-view mirror, can only provide an additional visibility of about 60 degrees. The remaining 100 degrees are invisible. We must pay more attention to it, especially when turning.
It is not only the concrete mixer truck, truck mounted crane transport vehicle, road obstacle removal vehicle, but also other vehicles should pay attention to the visual blind area in the driving process, otherwise it is easy to cause accidents.
