1、 The temperature decreases greatly in winter, the viscosity of engine oil becomes thicker in summer, the circulating resistance of crankshaft becomes larger, and the fluidity of engine oil is poor, resulting in increased wear of piston and cylinder liner of concrete mixer. Therefore, use winter engine oil with low grade and good fluidity. It is recommended by the concrete mixer manufacturer to replace the engine oil of 10W-30 or 5W-30. The former can start at minus 15 degrees and the latter can start at minus 25 degrees.

二、检查防冻液

2、 Check antifreeze

加注防冻液前一定要对混凝土搅拌车发动机冷却系统进行一次认真的清洗。应使用10%的烧碱水溶液浸泡水箱一个小时，再将冲洗液排放，然后用软化水反复冲洗23次，以混凝土搅拌车发动机冷却系统中原积存的水垢，冲洗完后才能加注防冻液。

Before adding antifreeze, the engine cooling system of concrete mixer must be carefully cleaned. The water tank shall be soaked with 10% caustic soda aqueous solution for one hour, then the flushing solution shall be discharged, and then it shall be repeatedly flushed with demineralized water for 2 to 3 times to remove the scale accumulated in the engine cooling system of concrete mixer truck. Antifreeze can be filled after flushing.

同时，在加注防冻液前要检查混凝土搅拌车发动机冷却系统有无渗漏现象，并应及时排除后才能使用防冻液。防冻液使用中要实行定期检查。防冻液的有效期一般2年，为了减少浪费，防冻液加注后不要随意更换。

At the same time, before filling antifreeze, check whether there is leakage in the engine cooling system of concrete mixer, and remove it in time before using antifreeze. Regular inspection shall be carried out during the use of antifreeze. The validity period of antifreeze is generally 2 years. In order to reduce waste, do not replace the antifreeze after filling.

但是，应对使用中的防冻液实行定期定项检查，如发现比重增大、防冻液变稠、冰点上升，以及防冻液变浊、变质、变味、发泡等应及时更换。要选择低于车使用地区温度10度左右并具备冬季防冻、夏季防沸、防腐、防水垢的长效型的防冻液。

However, the antifreeze in use shall be inspected regularly. If the specific gravity increases, the antifreeze thickens, the freezing point rises, and the antifreeze becomes turbid, deteriorated, tastes and foamed, it shall be replaced in time. Choose a long-term antifreeze that is about 10 degrees lower than the minimum temperature in the area where the vehicle is used and has antifreeze in winter, anti boiling, anti-corrosion and waterproof scale in summer.

三、要检查电瓶

3、 Check the battery

混凝土搅拌车蓄电池怕低温，在冬季来临之前，须补充蓄电池的电解液，并检查存电情况，温暖天气时使用正常的蓄电池，在寒冷的气温下经常失效，故蓄电池的保养应引起司机朋友的特别重视。要看是否需添加蒸馏水，同时察看清洁电瓶的极柱，并检测电瓶液的比重。对启动无力、使用时间超过两年的电瓶换掉。

The battery of concrete mixer truck is most afraid of low temperature. Before winter, it is necessary to supplement the electrolyte of the battery and check the power storage. The normal battery is used in warm weather and often fails in cold temperature. Therefore, the maintenance of the battery should be paid special attention to by the driver's friends. To see whether distilled water needs to be added, check the pole of the clean battery and check the specific gravity of the battery liquid. It's best to replace the battery with weak start and used for more than two years.

四、混凝土搅拌车检查刹车和轮胎

4、 Check the brakes and tires of the concrete mixer

冬季雨雪天较多地面比较湿滑，所以要检查刹车和轮胎。要查看一下刹车油壶液面的高低，检验刹车会不会跑偏，混凝土搅拌车制动效果是否良好。对于轮胎的检查一是要看胎压是不是符合标准，二是要看混凝土搅拌车轮胎的磨损情况，如果轮胎花纹已磨光，轮胎有裂痕或破损的情况，应急时更换。

There are many rainy and snowy days in winter, and the ground is wet and slippery, so check the brakes and tires. Check the liquid level of the brake oil pot, check whether the brake will deviate and whether the braking effect of the concrete mixer is good. The inspection of tires depends on whether the tire pressure meets the standard and the wear of concrete mixer tires. If the tire pattern has been polished and the tire is cracked or damaged, replace it in case of emergency.

五、此外，有可能的话，在清洁玻璃的喷水壶里加入酒精来降低冰点，保证水壶里的水不会结冰，随时可以清洁挡风玻璃，保持良好的视线。另外，冬天橡胶会发硬收缩，所以混凝土搅拌车风扇皮带、空调皮带张力不要太紧，否则对混凝土搅拌车发电机的轴承有损伤，还会拉断皮带。

5、 In addition, if possible, add alcohol to the water spray kettle for cleaning the glass to reduce the freezing point and ensure that the water in the kettle will not freeze. The windshield can be cleaned at any time to maintain a good line of sight. In addition, the rubber will harden and shrink in winter, so the tension of fan belt and air conditioning belt of concrete mixer shall not be too tight, otherwise the bearing of concrete mixer generator will be damaged and the belt will be broken.
