When China's major cities impose restrictions on trucks, there is a kind of truck that can freely shuttle through the streets and alleys, that is, mixer trucks (of course, to go through the relevant procedures first). City construction can not do without concrete, and the transport of concrete can not do without mixer, but also created the rapid development of the mixer market. But driving concrete mixer is not a simple thing, I have several years of concrete mixer driving experience, here I would like to give you a brief description of concrete mixer truck, transportation, unloading and other operations experience.

Check iligently to ensure that there is no problem preparation for excipients to prevent condensation.

For the mixer, maintaining the normal operation of the vehicle is the most important thing, because once the vehicle is broken in the middle of the road, the occurrence of stuffy tank incident, two hours after stopping the tank, the concrete inside the tank will be scrapped, will cause great economic losses. Therefore, we should carry out maintenance and repair on time. Before leaving the vehicle, the lighting, oil, lubricants, brakes, engines and other parts should be carefully inspected to ensure that the vehicle can run normally.

Because of the high temperature in summer or other reasons, the concrete may be too dry, no water can not be discharged, which requires checking the water tank before leaving the car, to ensure that there is enough water and water reducer, when discharged to save the concrete can not be stuffy. Before ignition, make sure that the mixing tank is in a stop state, so as not to damage the reducer by the huge force produced by the high-speed rotation of the tank.

Familiar with road turn and slow running road.

Drivers who drive mixers know that mixers have a high center of gravity and are prone to rollover during transportation, especially when turning. I used to drive a mixer when I was in a bend and slowed down the speed of the tank in advance, so the car was more stable.

Familiar with transport conditions, it is best to take appropriate low-grade passage in bad places to avoid risk factors, such as pits, stones, boards and so on. Reduce gears and speed up the tank before going up the slope so that it can climb steadily and keep the concrete from flowing out. Test whether the brakes are normal before downhill and no neutral skid. When the speed limit is high and the width limit is wide, the specific data should be clear ahead of time to ensure the normal traffic of the vehicle.

More attention should be paid to avoid accidents in vehicles.

The final site of concrete belongs to the site, the site road conditions are more complex, the roadbed is soft, various building materials piled up more disorderly, so in and out of the site must first check the road conditions, find a good route. I've seen a lot of stuck tires, overturned cars, collapsed routes, and so on. I can only advise you to be careful and careful. Many construction sites have strict control over the speed of vehicles per hour, slowing down when entering and leaving the site, mainly to ensure safety, but also won't let the site people trouble you.

Site roads are relatively narrow, many times it is impossible to stop in place, to carry out repeated adjustments and movements, this time on the low-grade start, the site soft steering wheel hit too hard but not work, it is suggested that small angle adjustment, more than a few times the vehicle parked in the designated position. It's better to have someone familiar with the road command on the site, which saves a lot of time and ensures safety.

? unloading should not be careless, multi-layer procedures should be in place, heavy load rollover trailers.

Discharge is also a knowledge, first of all, the technical aspects: before discharging, let the mixing tank run at full speed, so that the concrete more uniform; unloading, as far as possible to maintain a smooth vehicle, the hopper chute wet, easy to unload after washing; after discharging, to carefully flush the tank blades. If the site water is sufficient, the tank can be turned several times after adding water, for thorough washing, otherwise long-term past will cause the deposition of concrete in the tank.

In other words, the procedure problem, unloading should be stared at, do not try to save trouble to let go, many of the feeding unions will take advantage of the driver's absence when the random operation of the feeding lever, and then their own stare at the side, can also ensure normal operation, do not cause damage to the tank, reducer, carriage wheel and so on. Do well with the discharge workers, foreman and workers around. After all, acquaintances do well. Finally, don't forget to ask the person in charge to sign. This is very important. If you don't sign, it means you've done nothing.
