Determine the working position of handbrake handle of mixer truck

首先，肯定自上料混凝土搅拌罐车手刹手柄的工作位置。普遍来说，当手柄拉到整个行程的四分之三时，手刹系统就应该处于正常的刹车位置。应该先找出这个工作点，这个工作点可以经过数棘轮的响声来肯定，普遍5～7格之间是正常的位置。

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.

检查搅拌车手刹机构的效能

Check the efficiency of hand brake mechanism of mixer truck

检查自上料混凝土搅拌罐车手刹机构的效能，也就是看看手刹是否有效工作。把汽车开到坡度较大、路面状况良好的斜坡上，踩住制动踏板，挂空挡，将手刹手柄拉到刚才肯定的工作点位置。慢慢松开制动踏板，如果自上料混凝土搅拌罐车没有发生滑动，就说明手刹的效能良好。

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.

测试手刹的灵敏度

Test the sensitivity of the handbrake

除了制动效能外，还应该检查搅拌车手刹的灵敏度，这对斜坡起步特别重要。在没有坡度的路面上慢速行驶，缓缓地提拉手刹手柄，感觉一下搅拌车手柄的灵敏度和接合点。这种检查方法会使搅拌车手刹机构磨损，所以检查的次数不宜太多。在检查过程中，如果发现搅拌车手刹的制动效能或灵敏度不理想，通常可以通过调节手刹的操作钢缆来解决。在搅拌车手刹手柄的底部与钢缆的连接处有一个可调的补偿机构，松开锁紧螺帽就可以拉伸刹车钢缆的长度。可有些搅拌车的调节机构设在车底，如果不便调整，应该交由的维修人员来处理。

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.
