Small mixer has become an indispensable tool and equipment in the construction industry. In order to ensure the safety of the agitator, all components must be inspected daily. If any damage is found, it shall be handled in time. Among them, the brake pads are very important, which will endanger life and safety. To reach the service life in time, I'll give you a detailed introduction.

　　1. 小型搅拌车的日常检查

　　1. Daily inspection of small mixer

　　1. 预热前检查发动机

　　1. Check the engine before preheating

　　检查液压油的容量(检查油位的存储),检查减速机的润滑油是否漏水,检查液压系统的液压油是否漏水,检查是否有漏接头,检查控制装置的控制手柄是否被放置在停止位置,并检查连接紧固件不应松动。

　　Check the capacity of the hydraulic oil (check the storage of the oil level), check whether the lubricating oil of the reducer leaks, check whether the hydraulic oil of the hydraulic system leaks, check whether there is a leaking joint, check whether the control handle of the control device is placed in the stop position, and check that the connecting fasteners should not be loose.

　　2. 发动机预热时的检查现场

　　2. Inspection site during engine preheating

　　检查油泵是否有异常声音，液压马达是否有异常声音，减速器是否有异常声音，泵是否正常转动，搅拌缸进料转动是否正常运转及转动。

　　Check whether there is abnormal sound in oil pump, hydraulic motor, reducer, pump and mixing cylinder.

　　3.检查辅助出料槽的锁紧卡环、出料槽的锁紧手柄、防旋转手柄是否锁紧。

　　3. Check whether the locking snap ring, locking handle and anti rotation handle of the auxiliary discharge chute are locked.

　　4. 搅拌车各连接螺栓拧紧力矩检查

　　4. Inspection for tightening torque of connecting bolts of mixer truck

　　副车架与主副梁、减速机与罐体等之间的连接采用高强度螺栓，必须定期拧紧。时间更长不得超过两个月。下表为不同螺栓的拧紧力矩值

　　The connection between the subframe and the main and auxiliary beams, reducer and tank body, etc. adopts high-strength bolts, which must be tightened regularly. The maximum time shall not exceed two months. The following table shows the tightening torque values of different bolts

　　二、小混车刹车片保养小贴士

　　2、 Tips for maintaining the brake pads of small hybrid cars

　　1. 检查刹车片的小搅拌器每5000在正常驾驶情况下,不仅检查剩余的厚度,而且检查鞋子的穿着状态的小型搅拌机,两边的磨损程度是否相同,是否返回位置是的,等等。任何异常情况必须立即处理。

　　1. Check the small mixer of the brake pad every 5000 km under normal driving conditions, not only check the remaining thickness, but also check the wearing condition of the shoes, whether the wear degree of both sides is the same, whether the return position is free, etc. Any exceptions must be handled immediately.\

　　2、小型搅拌车、刹车蹄片一般都是由铁衬板和摩擦材料两部分组成，千万不要等到摩擦材料零件都磨损了才更换蹄片。例如，一辆小型混合车的前制动蹄片在新膜中厚度为14毫米，而更换后的厚度为7毫米，其中包括超过3毫米的铁衬厚度和近4毫米的摩擦材料厚度。

　　2. Small mixer and brake shoes are generally composed of iron lining plate and friction material. Do not replace shoes until the friction material parts are worn. For example, the front brake shoes of a small hybrid car have a thickness of 14 mm in the new film, while the replaced shoes have a thickness of 7 mm, including a thickness of more than 3 mm of iron lining and a thickness of nearly 4 mm of friction material.

　　有些小型搅拌器具有制动蹄片报警功能，一旦磨损达到，该仪器就会报警提示更换蹄片。要达到使用极限，必须更换蹄铁，即使使用一段时间，也会降低制动效果，影响小型混合车的。

　　Some small agitators have the brake shoe alarm function. Once the wear is reached, the instrument will give an alarm and prompt to replace the shoe. To reach the use limit, the shoe must be replaced. Even if it is used for a period of time, the braking effect will be reduced and the safety of small hybrid vehicles will be affected.

　　3.更换时应更换原厂提供的小型搅拌器的刹车片。只有这样才能提高小搅拌器的刹车片与刹车片之间的制动效果，减少磨损。

　　3. Replace the brake pads of the small mixer provided by the original manufacturer. Only in this way can the braking effect between the brake pad and the brake pad of the small agitator be improved and the wear is reduced.

　　4. 更换闸瓦时，必须使用专用工具推动制动副泵。不要用其他的撬棍往回压，否则会导致刹车片夹紧导螺杆弯曲而堵塞刹车片。

　　4. When replacing the brake shoe, special tools must be used to push the brake auxiliary pump. Do not press back with other crowbars, otherwise the brake pad clamping guide screw will be bent and the brake pad will be blocked.

　　5、更换后，必须踩几脚刹车，以小车上的小混蹄与刹车盘的间隙，导致没有刹车，容易发生事故。

　　5. After replacement, several foot brakes must be applied to eliminate the gap between the small mixed shoes on the car and the brake disc, resulting in no brake and prone to accidents.

　　6. 更换小搅拌器的制动蹄后，应调整200，以达到良好的制动效果。新更换的小搅拌器的鞋应小心驱动。

　　6. After replacing the brake shoe of the small mixer, it should be adjusted to 200 km to achieve good braking effect. The shoes of the new small mixer should be driven carefully.
