搅拌车车轮在脱落之前，必定有预兆。只要做好日常检查和定期发现搅拌车的车轮螺栓折断等异常情况，不要继续行驶。如果行车途中需要更换轮胎，而更换轮胎时不正确的操作等，都有可能引起车轮脱落、导致重大交通事故。更换轮胎时，必须正确使用车轮螺栓、螺母检查，搅拌车的车轮脱落事故是可以避免的。

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.

司机也可以进行自检，可以目测检查搅拌车的车轮的螺栓、螺母是否齐全、生锈，或者龟裂或破损。检查搅拌车的车轮螺栓可从车轮螺母处突出的尺度是否一致开始，如果出现参差不齐的情况，则有可能造成螺母松动或螺栓折断。

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.

搅拌车轮胎脱落主要是螺栓和螺母的问题，但轮胎胎体也要注意。平时司机要检查轮胎是否存在龟裂、破损及异常磨损，检查轮胎花纹沟的深度，同时测量轮胎气压是否在规定范围之内。

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.

如果在搅拌车轮胎气压异常的情况下行驶，则有可能导致搅拌车轮胎放炮或爆胎，这也都会出现一定的危险。在搅拌车轮胎气压很低的情况下行驶或放炮后继续行驶，会增大搅拌车的车轮螺栓的压力，就可能导致螺栓折断、发生搅拌车轮胎脱落事故。

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.

此外平日注意要经常检查搅拌车轮胎是否有扎伤、划伤，是否有因断线造成的突起，视情况调换车辆轮胎位置或更换；轮胎一般使用三年或八、九万就应该更换。经常检查搅拌车轮胎气压，使其保持在标准范围内。此外，为搅拌车轮胎充氮气能保持胎压稳定，减少爆胎几率。

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.

切忌采用给轮胎放气或泼水的方法给轮胎散热，这样做会造成搅拌车轮胎胎面和胎侧胶层因收缩不均而导致爆裂。当搅拌车轮胎气温升高时，应将搅拌车停在阴凉处，使轮胎自然冷却。

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.

当混凝土搅拌机在高速公路上发生爆胎时，千万不要惊慌，不要猛踩刹车，双手应全力控制方向盘，切忌急转方向，让搅拌车沿原行驶方向继续行驶一小段，而后轻点刹车；待车速自然慢下后，轻转方向停靠应急车道；打开双闪提示灯，并将警告标志放置于搅拌车后方150米外。

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.
