Why Are Concrete Mixer Truck Getting Heavier


Recently, many users of concrete mixer trucks have reported that their tank trucks have become heavier and the same is going uphill. Now they are leaking materials from the mouth of the tank. After weighing, they find that they weigh more than 1 ton than the new trucks. Why does this happen?

The concrete mixer truck is a vehicle for transporting concrete. If the usual cleaning is not in place, it is easy to stick to the tank. Now let's talk about the matters needing attention in the use of concrete mixer trucks.

Preventing concrete from being attached to the tank

First, bring some spare water reducing agents with you

Water reducing agent is a concrete admixture that can reduce the amount of water for mixing under the condition that the slump of the concrete is maintained. It can be carried on the vehicle and can adjust the concrete well. However, when adding water-reducing agent, we must remember that there is a laboratory at Shangye Station, otherwise the quality of concrete is not enough, and the consequences will be serious.

Second,Back to the station to check the amount of water in the water storage tank

Every time you return to the station after unloading the material, check the water amount in the water storage tank. It is best to keep the water in the water tank full at all times for emergency.

Third, Check the concrete quality before leaving the station

May be due to different raw materials, the concrete quality of each car will vary. When leaving the concrete after installation, be sure to check the slump and ease of the concrete in the tank, and pay attention to the early setting of the concrete and the precipitation of the concrete.

Fourth. Minimize concrete mixer truck travel time

The transportation distance of concrete is generally within a radius of 20 kilometers. Plan the driving route and vehicle performance before leaving the vehicle to minimize the travel time of the concrete mixer truck on the road.

Fifth, in special circumstances, in order to reduce losses, discharge first

If you encounter artificial or force majeure factors that prevent unloading for a long time, you should check the concrete condition in the tank at any time. Once the concrete is found to start to set. Unloading should be carried out immediately to prevent the entire tank from being condensed.

Don't be afraid of trouble, try to clean at any time

I. Rinse at any time during the use of the concrete mixer truck

After each unloading, use the tanker to bring the water gun to rinse the mouth, blades, feed inlet, tank body and corner corners to prevent the concrete from accumulating more and more after solidification, resulting in poor cleaning.

2. Wash the concrete mixer truck thoroughly after closing it

After the daily transportation task is over, add more than 1 cubic meter of fresh water to the tank, and quickly rotate the tank for cleaning. Conditioned mixing station can also add stones to the tank, the effect will be better.

Tips for sharing water tank operation steps

First, control the air pressure of the water storage tank and often tighten each pipe joint

How much air pressure should be injected into the tank, this is already set at the factory and does not need to be adjusted by yourself. If it is necessary to adjust in special circumstances, it is recommended to control the pressure at about 3.5Mpa. In addition, in the new car and daily use, the place where the pipeline is connected must be tightened at any time to prevent it from falling off.

Steps for adding water to the tanker

The arrangement of each tanker's water refilling place is very similar. Generally, the water tank is exhausted-filled with water-the water refilling valve is closed; when not in use, it is best to place the lever in the middle.

Drain the remaining water in the water storage tank in winter

In winter, especially the users in the north should drain the water in the water tank and water pipe after collecting the car every day, and blow compressed air into the water pipe to blow out the remaining water in each pipe to prevent the pipe from freezing and cracking due to icing.
