There must be an omen before the wheel of the mixer falls off. As long as daily inspection is done and abnormal conditions such as broken wheel bolts of the mixer are found regularly, do not continue driving. If the tire needs to be replaced during driving, and the incorrect operation during tire replacement may cause the wheel to fall off and cause a major traffic accident. When changing tires, the wheel bolts and nuts must be used correctly for inspection. The wheel falling off accident of the mixer truck can be avoided.
The driver can also conduct self inspection, and visually check whether the bolts and nuts of the wheels of the mixer truck are complete, rusted, cracked or damaged. Check whether the wheel bolts of the mixer truck can start from whether the protruding dimensions of the wheel nuts are consistent. If there are uneven conditions, it may cause the nuts to loosen or the bolts to break.
The falling off of mixer tire is mainly caused by bolts and nuts, but the tire carcass should also be paid attention to. At ordinary times, the driver should check whether the tires have cracks, damages and abnormal wear, check the depth of tire grooves, and measure whether the tire pressure is within the specified range.
If you drive under the condition of abnormal tire pressure of the mixer truck, it may cause the tire of the mixer truck to explode or burst, which will also pose a certain danger. Driving when the tire pressure of the mixer truck is very low or continuing to drive after shooting will increase the pressure of the wheel bolts of the mixer truck, which may lead to bolt breakage and tire falling off accident of the mixer truck.
In addition, on weekdays, pay attention to regularly check whether the mixer tires are pricked, scratched, and whether there are protrusions caused by broken wires. Change the position of the vehicle tires or replace them according to the situation; Tyres should be replaced after three years or 80000 or 90000 kilometers. Frequently check the tire pressure of the mixer truck to keep it within the standard range. In addition, filling nitrogen into the mixer tire can keep the tire pressure stable and reduce the probability of tire burst.
Do not deflate or splash water on the tire to dissipate heat, which will cause the tire tread and sidewall rubber layer of the mixer truck to burst due to uneven shrinkage. When the temperature of the mixer truck tire rises, the mixer truck should be parked in a cool place to cool the tire naturally.
When the concrete mixer has a flat tire on the highway, don't panic, don't step on the brake violently, control the steering wheel with both hands, don't turn the direction sharply, let the mixer continue to drive a short distance along the original driving direction, and then gently brake; When the speed naturally slows down, turn gently and stop in the emergency lane; Turn on the double flashing light and place the warning sign 150 meters behind the mixer.
