Determine the working position of handbrake handle of mixer truck

首先，肯定自上料混凝土攪拌罐車手剎手柄的工作位置。普遍來說，當手柄拉到整個行程的四分之三時，手剎系統就應該處于正常的剎車位置。應該先找出這個工作點，這個工作點可以經過數棘輪的響聲來肯定，普遍5～7格之間是正常的位置。

First of all, confirm the working position of the handbrake handle of the concrete mixer. Generally speaking, when the handle is pulled to three-quarters of the whole stroke, the handbrake system should be in the normal braking position. The working point should be found out first. The working point can be confirmed by the sound of ratchets. Generally, the normal position is between 5 and 7 grids.

檢查攪拌車手剎機構的效能

Check the efficiency of hand brake mechanism of mixer truck

檢查自上料混凝土攪拌罐車手剎機構的效能，也就是看看手剎是否有效工作。把汽車開到坡度較大、路面狀況良好的斜坡上，踩住制動踏板，掛空擋，將手剎手柄拉到剛才肯定的工作點位置。慢慢松開制動踏板，如果自上料混凝土攪拌罐車沒有發生滑動，就說明手剎的效能良好。

Check the efficiency of the hand brake mechanism of the concrete mixer, that is to see whether the hand brake works effectively. Drive the car to the slope with large slope and good road condition, step on the brake pedal, shift to neutral gear, and pull the handbrake handle to the working point position confirmed just now. Slowly release the brake pedal, if the concrete mixer does not slide, it shows that the hand brake has good performance.

測試手剎的靈敏度

Test the sensitivity of the handbrake

除了制動效能外，還應該檢查攪拌車手剎的靈敏度，這對斜坡起步特別重要。在沒有坡度的路面上慢速行駛，緩緩地提拉手剎手柄，感覺一下攪拌車手柄的靈敏度和接合點。這種檢查方法會使攪拌車手剎機構磨損，所以檢查的次數不宜太多。在檢查過程中，如果發現攪拌車手剎的制動效能或靈敏度不理想，通常可以通過調節手剎的操作鋼纜來解決。在攪拌車手剎手柄的底部與鋼纜的連接處有一個可調的補償機構，松開鎖緊螺帽就可以拉伸剎車鋼纜的長度。可有些攪拌車的調節機構設在車底，如果不便調整，應該交由的維修人員來處理。

In addition to the braking efficiency, the sensitivity of the hand brake of the mixer should also be checked, which is particularly important for starting on a slope. Drive slowly on the road without slope, slowly pull the handbrake handle to feel the sensitivity and joint point of the mixer handle. This inspection method will make the mixer hand brake mechanism wear, so the frequency of inspection should not be too much. In the process of inspection, if it is found that the braking efficiency or sensitivity of the hand brake of the mixer is not ideal, it can be solved by adjusting the operation cable of the hand brake. There is an adjustable compensation mechanism at the connection between the bottom of the handbrake handle and the steel cable, and the length of the brake cable can be stretched by loosening the locking nut. The adjustment mechanism of some mixers is set at the bottom of the truck. If it is inconvenient to adjust, it should be handled by professional maintenance personnel.
