Why is my 6m3 concrete mixer truck getting heavier

I received a call last week in which a friend told me about his concrete mixer truck getting heavier. He bought a 6m3 concrete mixer truck from us a year ago. Recently he found that it weighs much heavier than before. What’s worse, concrete falls off once the truck climbs a slope. This is a typical problem that many new drivers of concrete mixer trucks may be confronted with? What’s wrong with the truck, then? The reason lies in adhesion stick of concrete.

As known to all, concrete solidifies quickly once kept still. That’s why a concrete mixer truck has a mixing tank rotating continuously during delivery of concrete. Cleaning work of a mixer truck must be carried out fully and regularly, or else the concrete would get stuck to the mixer tank and other parts of the truck. As a result, the truck gets heavier and heavier. Among leading concrete mixer truck manufacturers, Haomei would like to introduce the key solution to the problem: swift loading and unloading.

To realized swift loading and unloading of a concrete mixer truck, here are five tips. First, keep water reducer at hand. The water reducer is an admixture reducing water demand of concrete while maintaining the original slump degree. But the reducer should not be applied unless people from the concrete station lab permits, otherwise a driver may not be able to control the feeding amount and make the concrete strength weaker than as required. Second, check the water amount every time after delivery. The truck driver should checker the amount of water in the water tank every time after he drives back to the concrete batching plant station, making sure that the tank is always full. In this way you can add water to the concrete in case of solidification. Third, check the concrete quality before delivery. Owing to variation in raw materials, concrete may also vary, so you need to check its quality every time after loading a truck, making sure the concrete will not solidify in advance and fall apart unexpectedly. Fourth, reduce delivery time. The best delivery distance diameter is within 30km, and you’d better schedule the route in advance, trying to get the concrete delivered in the shortest period of time. Fifth, unload in case of emergencies. Sometimes you may get stuck in the traffic or other insolvable conditions, when you have to keep the truck unloaded for a long time. You should inspect the concrete inside the tank from time to time, and unload the truck once the concrete begins to solidify after contacting your manager. Once the concrete get solidified completely, the whole truck will become a punch of metal waste.
