4、 装置驱动：

4. Unit drive:

一旦液压泵发生故障，可按以下紧急驱动步骤进行驱动：

Once the hydraulic pump fails, it can be driven according to the following emergency driving steps:

a、 转被好紧急驱动软管（即应急软管）；

a. Turn the emergency drive hose (i.e. emergency hose);

b、 将故障车（被驱动车）熄火，卸下液压马达上的高压油管接头；

b. Turn off the faulty vehicle (driven vehicle) and remove the high-pressure oil pipe connector on the hydraulic motor;

c、 将故障车（驱动车）熄火，将其液压马达的高压油管接头卸下，并与故障车上液压马达的对应接头软管相连接；

c. Turn off the fault vehicle (drive vehicle), remove the high-pressure oil pipe connector of its hydraulic motor and connect it with the corresponding connector hose of the hydraulic motor on the fault vehicle;

5、操作是注意几个要点

5. Operation is to pay attention to several points

1、在混凝土搅拌车作业前需进行检查，确认转向、制动、灯光、信号系统灵敏有用，搅拌运输车滚筒和溜槽无裂纹和严重损伤，搅拌叶片磨损在正常范围内，底盘和副车架之间的U形螺栓连接良好。

1. Before the operation of the concrete mixer truck, it is necessary to check to confirm that the steering, braking, lighting and signal systems are sensitive and useful, the drum and chute of the mixer truck are free of cracks and serious damage, the wear of the mixing blades is within the normal range, and the U-shaped bolts between the chassis and the subframe are well connected.

2、了解施工要求和现场情况。选择行车路线和停车地点。

2. Understand the construction requirements and site conditions. Select the driving route and parking place.

3、在社会道路上行驶需遵守交通规则。转弯半径应符合使用说明书的要求，时速不大于15km。进站时速不大于5km。

3. Traffic rules shall be observed when driving on social roads. The turning radius shall meet the requirements of the operation manual, and the speed per hour shall not be greater than 15km. The speed at the station shall not be greater than 5km.

4、作业时，严禁用手触摸旋转的滚筒和滚轮。

4. During operation, it is forbidden to touch the rotating drum and roller by hand.

5、在混凝土搅拌车倒车卸料时，需服从指挥，注意周围人员，发现异常立即停车。

5. When reversing the concrete mixer for unloading, obey the command, pay attention to the surrounding personnel, and stop immediately in case of abnormalities.

6、严禁在高压线下进行混凝土搅拌车清洗作业。

6. It is strictly prohibited to clean the concrete mixer under the high-voltage line.

6、日常维护

6. Routine maintenance

由于混凝土会在短时间内凝固成硬块，且对钢材和油漆有一定的腐蚀性，所以每次使用混凝土贮罐后，洗净粘附在混凝土贮罐及进出料口上的混凝土是每日维护需认真进行的工作。其中包括：

Since the concrete will solidify into hard blocks in a short time and have certain corrosivity to steel and paint, cleaning the concrete adhered to the concrete storage tank and the inlet and outlet after each use of the concrete storage tank is a serious work to be carried out in daily maintenance, including:

a．每次装料前用水冲洗进料口，使进料口在装料时保持湿润；

a. Wash the feed port with water before each loading to keep the feed port wet during loading;

b．在装料的同时向随车自带的清洗用水水箱中注满水；

b. Fill the cleaning water tank with water while loading;

c．装料后冲洗进料口，洗净进料口附近残留的混凝土；

c. Wash the inlet after loading and clean the residual concrete near the inlet;

d．到工地卸料后，冲洗出料槽，然后向混凝土贮罐内加清洗用水30—40 L；在车辆回程时保持混凝土贮罐正向慢速转动；

d. After unloading at the construction site, wash the discharge tank, and then add 30-40 l of cleaning water to the concrete storage tank; keep the concrete storage tank rotating forward and slowly when the vehicle returns;

e．下次装料前切记放掉混凝土贮罐内的污水；

e. Remember to discharge the sewage in the concrete storage tank before the next loading;

f．每天收工时全部清洗混凝土贮罐及进出料口周围，保证不粘有水泥及混凝土结块。

f. Clean the concrete storage tank and around the inlet and outlet at the end of each day to ensure that there is no cement and concrete caking.
