The first two steel plates of small mixer are easy to break. What is the reason for this problem?

小型搅拌机的前钢板由9个部件组成。许多人报告说，搅拌车的块和第二块在使用过程中很容易折断。是什么原因？

The front steel plate of small mixer consists of 9 parts. Many people report that the first and second pieces of the mixer are easily broken during use. What is the reason?

（1）紧急制动器的过度使用。在高山上行驶时，在下坡道路上使用紧急制动可能会导致前面板断裂。由于制动力，搅拌车的大部分负载质量都会被前板簧推动并承受，这很容易造成板簧的疲劳损坏。建议使用排气制动器以减少紧急制动。

(1) Excessive use of emergency brakes. When driving on high mountains, the use of emergency braking on downhill roads may cause the front panel to break. Because of the braking force, most of the load mass of the mixer will be pushed and borne by the front leaf spring, which is easy to cause the fatigue damage of the leaf spring. Exhaust brake is recommended to reduce emergency braking.

（2）前轮制动器调节太紧。如果后轮制动器性能不佳或出现突然问题，则紧急制动器会施加过大的冲击力来破坏前板簧。

(2) Front wheel brake adjustment too tight. If the performance of the rear wheel brake is poor or there is a sudden problem, the emergency brake will exert excessive impact force to destroy the front leaf spring.

（3）路面不良，超载，超速，前板簧承受过大的冲击力，容易造成损坏。

(3) Bad road, overload, overspeed, front leaf spring bear too much impact, easy to cause damage.

（4）前板簧经常长时间过载，弹性和刚度降低，并且疲劳损坏。

(4) The front leaf spring is often overloaded for a long time, its elasticity and stiffness are reduced, and it is fatigued.

（5）更换质量较差的钢板弹簧，叶片弯曲不符合标准。钢板材料不好或热处理不好，导致应力不均和断裂。

(5) The leaf spring with poor quality was replaced, and the blade bending did not meet the standard. The steel plate material is not good or heat treatment is not good, resulting in uneven stress and fracture.

为了防止小型搅拌机的前板簧的块和第二块自动加载，建议采用以下方法：

In order to prevent the automatic loading of the first and second front leaf springs of the small mixer, the following methods are recommended:

（1）检查并保持及时，以确保片簧润滑良好，并正确调整车辆的制动器。

(1) Check and keep in time to ensure that the leaf spring is well lubricated and the brake of the vehicle is adjusted correctly.

（2）少用紧急制动器，多用发动机排气制动器，负荷均匀，无偏差，无过载。

(2) Less use of emergency brake, more use of engine exhaust brake, uniform load, no deviation, no overload.

（3）更换前钢板时，必须使用钢板以确保弯曲度符合要求。使用山东弹簧厂和重庆弹簧厂生产的钢板弹簧。

(3) When replacing the front steel plate, high quality steel plate must be used to ensure that the bending meets the requirements. It is better to use the leaf spring produced by Shandong spring factory and Chongqing Spring Factory.

（4）在崎岖不平的道路上行驶时，在下坡行驶时，应控制小型搅拌机的速度并驱动弯道。转弯不应该太紧急。

(4) When driving on rough roads and downhill, the speed of small mixer should be controlled and the curve should be driven. The turn should not be too urgent.

以上方法是小型搅拌车前面板破损的原因，以及如何防止其破损的方法，希望大家予以关注。

The above methods are the reasons for the damage of the front panel of the small mixer truck, and how to prevent the damage, I hope you will pay attention to them.
