How to avoid dumping of dump truck trailers

Recently, there were a few posts about dump semi trailers overturning when unloading on the Forum of Truck House. In addition to everyone’s regrets, more enthusiastic truck drivers have shared their experience of driving dump truck trailers and unloading with everyone. Now, we will make a simple integration of your suggestions to facilitate everyone to check and let more truck drivers avoid this. 

1. The unloading ground should be in same level

This is mentioned in the reminders of almost all truck drivers. This is also the first issue that dump truck trailers drivers should pay attention to. The ground at the dump site must be in same level, especially the left and right sides.

If the center of gravity shifts after the dump trailer cargo boxes are gathered together, a large center offset will occur, which is very prone to overturning.

2. The ground should be strong to prevent the dump trailer from getting stuck

There is another possibility on a flat road. The dump semi trailer is heavy and the ground is soft. After lifting, the rear wheel is stressed and one side of the tire is sunken.

In response to this situation, the suggestions given by dump truck drivers are more to pay more attention when unloading the dump trailers. When the bucket is halfway, pay attention to check whether the tires on both sides of the car are stuck. It is best to have someone outside the dump semi trailer to help and watch. Whether the hydraulic cylinder is tilted or not, if it is tilted, use a slow gear to lower the top and change to a stable place to lift.

QUEST VEHICLE customer’s driver feedback experience:

First find a stable place (must be stable!) Open the rear baffle and slowly raise the top! When you reach the first section, you must get out of the dump truck to check whether the stones behind it are blocked. If it is not blocked, you can continue to rise to the second section. At this time, pay attention. Since all the weight is behind, the rear axle tires will bear Increase the weight, check whether the tires on both sides have collapsed, if there is collapse, drop the top, let the dump trailer go to a stable place to lift! If there is no collapse, you can walk forward slowly, and then lift. When lifting, always keep the body stable! Note: When you bring forward, you must walk slowly and brake slowly. Otherwise, the dump trailer body shakes a lot and it is easy to cause rollover!

3. The rear bucket door has to be opened

The unloading location is selected correctly, and the driver also needs to pay attention to the operation. The first step is to open the rear bucket. It seems very simple and does not require common sense to remind, but in the previous accidents, there was a rollover due to this situation. condition. If you forget to open it, the center of gravity of the entire vehicle will rise after the body is raised, and the road will be uneven, which will cause serious consequences!

4. Avoid breaking the car door

Now that there are more dump truck trailers loaded, the unloading volume is also large. When unloading, the driver should also pay attention to avoid pushing the door onto the cargo.

The specific driving method:

QUEST VEHICLE talked about my most common method, which is to pull on the air-stop brake and lift the bucket. When I was more than halfway up, I felt that the dump semi trailer was struggling because the tail of the cargo box hit the unloaded cargo. At this time, the air-stop brake must be released. If the top strength is strong, the dump semi trailer will usually move forward by itself. If not, just slide forward by yourself, don't walk too much at once, or the unloaded goods will be pulled by you for a long time. Then it's easy to repeat. A friend of mine likes to pull the air-stop brake to his head. As a result, the back door was deformed many times. The bucket was not closed tightly after falling down. The back door of the school was troublesome.

● For different goods, the unloading methods are different

Different goods and different unloading environments have different driving methods for drivers. The following is the experience given by several netizens:

QUEST suggestions:

1. Rock coal, you can't lift it up all at once, otherwise your handbrake will not be able to hold it, and you will rush forward. The rock coal should be unloaded a little bit shallower by itself.

2. Stone powder. The first four and the last eight should be made of plastic film, which makes it easier to unload. If you can’t lift it up, you can wait for a while, or put the car back a little bit.

3. Ron powder. This kind of thing depends on the dressing. If it’s dry, it’s easy to unload. If it’s wet, you have to be careful. The key is that the density of this thing is high, the front is lighter, and the back is a little more focused, so it’s easier to unload
