For the concrete mixer truck, it is important to keep the normal operation of the vehicle, because once the vehicle breaks down on the road and the tank is closed for two hours, the concrete in the tank will be scrapped, which will cause great economic losses. An old driver knows to prepare accessories in advance to prevent cement slurry from setting.

由于夏季的到来温度比较高的原因，可能会导致混凝土太干了，没有水放不出料，这就要求搅拌车司机在出车之前检查水箱，以保证足够多的水和减水剂。

Due to the high temperature in summer, the concrete may be too dry to discharge without water, which requires the mixer driver to check the water tank before leaving the truck to ensure enough water and water reducing agent.

老司机提醒必须熟悉路况，转弯慢行。

The old driver reminds us to be familiar with the road conditions and turn slowly.

只要了解搅拌车的朋友都知道，搅拌车比较高，运输过程中容易发生侧翻，尤其是在转弯的时候。遇到拐弯的地方提前减速，慢行过弯。在之前就熟悉路况，避让容易发生危险的因素，比如：大坑、石子、木板等。

As long as you know the mixer truck friends know, the truck center of gravity is relatively high, prone to rollover during transportation, especially when turning. Slow down the corner ahead of time. It is better to be familiar with the road conditions in advance and avoid the dangerous factors, such as pits, stones, planks, etc.

上坡前提前减档、加快罐子的转速，这样才能稳步爬坡并且保证混凝土不流出。下坡前测试刹车是否正常，禁止空挡滑行。在限速限高限宽路段，提前清楚具体数据，保证车辆正常通行。

Before going up the slope, reduce the gear in advance and speed up the rotation speed of the tank, so as to steadily climb the slope and ensure that the concrete does not flow out. Before downhill, test whether the brake is normal, and do not slide in neutral gear. In the section of speed limit, height limit and width limit, the specific data shall be clear in advance to ensure the normal passage of vehicles.
