One light: when the self loading concrete mixer works, the heel is close to the road surface of the cab, the sole plate and the accelerator are kept flat, and the oil pedal is gently pressed.
Two stable: since the feeding type concrete mixer in the work, the throttle has to be stable. Under normal working conditions, the throttle opening should be around 70%.
Three separation: when the self loading concrete mixer is working, the sole plate should be separated from the brake pedal, and should be placed flat on the road of the cab instead of stepping on the brake pedal. The self loading concrete mixer often works on uneven construction sites. If the foot is always on the brake pedal, the body will move up and down, which will cause the driver to step on the brake pedal carelessly. In general, the way of adjusting the throttle speed down is used to control the engine condition and shift. The utility model provides a quick braking system for the concrete mixing truck, which is convenient for the concrete mixing truck to accelerate.
Si Qin: when the self loading concrete mixer is working, especially when the shovel is working, the bucket shall be filled with materials by the way of rotating the lifting and rotary bucket control lever of the circulating system under the condition of stable accelerator. The circulation system of lifting and rotating bucket control lever is called "diligence". This process is very critical and has a great impact on fuel consumption.
Five coordination: coordination is the ingenious cooperation between lifting and bucket control lever. The general shoveling process of self loading concrete mixer is to put the bucket flat on the road and drive steadily to the material pile. When the bucket is flat and there is resistance when shoveling to the material pile, the standard of lifting the arm first and then retracting the bucket should be followed. In this way, the resistance at the bottom of the bucket can be reasonably prevented, and the larger digging force can be fully used.
Six prohibitions: the first is to prohibit tire deviation. When the self loading concrete mixer works, when it encounters resistance and gives the accelerator fiercely, the tire will generally deviate. This kind of situation is generally caused by the improper operation of the driver, which not only increases the fuel consumption, but also damages the tire. In addition, it is forbidden to turn up the rear wheels. Because of the great digging force of the self loading concrete mixer, the driver is usually in the process of digging solid original soil and stone hill. If the actual operation is not good, it is very easy to cause the two rear wheels to tilt up and leave the ground.
