The usage rate of the hand brake of the self feeding mixer truck is very high, but the effect of the hand brake will decrease with the increase of usage times. Due to improper maintenance in daily life, sometimes the handbrake of the self feeding mixer truck is already applied, but it cannot truly brake. This is also a major safety hazard for the vehicle. Therefore, regular maintenance and upkeep should be carried out on the handbrake of the self feeding mixer truck.

①进行自上料搅拌车手刹工作点位置确认

① Confirm the position of the hand brake working point of the self feeding mixer truck

一般来说当自上料搅拌车手刹手柄拉到整个行程的70%时，自上料搅拌车手刹系统就应该处于正常的刹车位置。我们在日常使用中，应该先找出这个刹车工作点，可以通过数棘轮的响声数量来确定，一般5格到8格之间是正常的刹车位置。

Generally speaking, when the hand brake handle of the self loading mixer truck is pulled to 70% of the entire stroke, the hand brake system of the self loading mixer truck should be in the normal braking position. In daily use, we should first identify the working point of the brake, which can be determined by counting the number of rattling sounds. Generally, the normal braking position is between 5 and 8 squares.

②进行刹车效果确认

② Confirm the braking effect

把自上料搅拌车开到坡度比较大、路面状况比较好的斜坡上，踩住车辆刹车，挂空挡，将自上料搅拌车手刹手柄拉到工作点位置。慢慢松开脚刹（注意一定要慢，保证），如果更终自上料搅拌车没有发生滑动，就说明自上料搅拌车手刹的效能良好。

Drive the self loading mixer truck to a slope with a relatively large slope and good road conditions, apply the vehicle's brake, shift to neutral, and pull the hand brake handle of the self loading mixer truck to the working point position. Slowly release the foot brake (be sure to slow down to ensure safety). If the self loading mixer truck does not slip in the end, it indicates that the self loading mixer truck's handbrake is effective.

③进行自上料搅拌车手刹的灵敏度测试

③ Perform sensitivity testing on the hand brake of the self loading mixer truck

选一段平坦的路面，在路面上慢速行驶，轻轻地提拉手刹手柄，感觉一下自上料搅拌车手柄的灵敏度和接合点。如果发现自上料搅拌车手刹的制动效能或灵敏度不够理想，有经验的司机可以自行调节手刹的刹车线，也可以将自上料搅拌车开到就近的维修站，让维修人员帮忙调整。

Select a flat road surface and drive slowly on the road. Gently lift and pull the handbrake handle to feel the sensitivity and engagement point of the self loading mixer handle. If it is found that the braking efficiency or sensitivity of the hand brake of the self loading mixer truck is not ideal, experienced drivers can adjust the brake line of the hand brake themselves, or drive the self loading mixer truck to the nearest maintenance station for maintenance personnel to help adjust.
