One light: when the automatic feeding concrete mixer works, the heel of the truck should be close to the floor of the cab, the foot board should be parallel to the accelerator pedal, and the fuel pedal should be gently stepped down.
Two stable: in the operation of automatic feeding concrete mixer, the throttle valve should always be stable. Generally speaking, the throttle opening is about 70%.
Three separation: when the automatic feeding concrete mixer works, the pedal shall be separated from the brake pedal and placed on the floor of the cab. Do not depress the brake pedal. Mixer truck often works on the construction site with uneven road surface. If the foot is always on the brake pedal, the body will move up and down, which will cause the driver to accidentally press the brake pedal. Generally speaking, we should control the engine condition and shift by controlling the throttle deceleration. This not only avoids the overheat of the brake system caused by frequent braking, but also brings convenience to the rapid speed up of the automatic feeding concrete mixer.
Fourth duty: especially in shovel digging, when the throttle is stable, the bucket is filled with materials in a cycle by pulling the lifting and rotating control lever. The cyclic pull of the lift and bucket rotation levers is called diligence. This process is very important and has a great impact on fuel consumption.
Five coordination: coordination is the coordination of lifting and bucket control lever. The general shovel excavation process of automatic feeding concrete mixer is to place the bucket on the ground and drive into the pile body smoothly. When the bucket is parallel to the material pile, the principle of lifting the arm first and then retracting the bucket should be followed. This can reasonably avoid the resistance at the bottom of the bucket, so as to give full play to the larger excavation force.
Six prohibitions: first of all, it is strictly forbidden to skid the tires. When the truck is working, the tire slip often occurs at the door of the filler when it encounters resistance and violence. This phenomenon is usually caused by improper operation of the driver, which increases fuel consumption and damages the tires. Second, the rear wheels are strictly forbidden to warping. Because of the high excavation force of the automatic loading concrete mixer, drivers usually dig hard raw soil and stone mountain. If the operation is not correct, the two rear wheels are easy to rise and leave the ground.
