How to unload a rollover semi-trailer?

Dump truck is a kind of engineering vehicle, its principle is to drive the hydraulic mechanism through the engine, drive the lifting mechanism to complete the tilt to achieve the purpose of unloading, after the completion of unloading reset, greatly saving the unloading time and labor, shorten the transportation cycle, improve production efficiency, in mining, water construction, road construction and other fields of application is more extensive.

From the lifting way of the dump truck, it can be divided into the rear flip type and the side flip type, and today we focus on the side flip type semi-trailer.

In fact, most of the previous dump trucks are backflip, but the height of the backflip semi-trailer for the lifting rod is relatively high, usually the height of the rod is affected by the length of the carriage, and the longer the length of the rod is required. However, the design of the ejector rod is a climbing design, and the finer it is to the top, so the lateral stability of the lift is very unfavorable.

In this case, the rollover semi-trailer came out, and its biggest advantage is that the height of the lifting rod is smaller, even less than half the height of the back rollover rod. The top rod of the rollover semi-trailer is generally distributed evenly at the bottom of the cargo box in a word shape, and the lifting force is large, and the lateral stability is also improved. Especially for semi-trailers with long cargo compartages, rollover dump is more suitable.

In addition, the rollover dump truck is generally equipped with a shift bar in the design, which can help reduce rollover to a certain extent, but it can not be completely avoided, and it needs to be strictly regulated.

1.The unloading site shall be flat. This is the problem that the owner should first pay attention to, be sure to choose the place where the ground is flat to unload, especially the left and right sides can not exist slopes. If the center of gravity shift occurs after the cargo box of the dump truck is raised, it is very easy to cause rollover.

2.The floor for unloading shall be firm. The general weight of the dump truck is relatively large, if the ground is relatively soft, it is easy to lead to the wheel sinking, body shaking or vehicle rollover.

3.The guardrail of the unloading part is converted into a baffle. This is also a method provided by the owner to prevent the buried tire, the guardrail next to the tire is converted into a baffle, pay attention to the height of the ground, so that it is not easy to bury the tire when unloading.

4.Do not lift the pole all at once. It is recommended that the owner pay more attention to observe during the unloading process, observe the vehicle by lifting a section of the rod, and then raise the next section if there is no offset or buried tire.

5.Pay more attention to observation during unloading. During the unloading process, the owner must observe the changes of the carriage from the rear window, such as the sinking of the tire and the tilt of the body, the loading and unloading should be stopped immediately, and it is best to arrange another person outside the car to assist in the observation.

Some owners said that when the rollover semi-trailer is unloaded, it can maintain a certain Angle between the front and the carriage, generally no more than 45°, to maintain the balance of the body.

It is worth noting that due to the lifting mode of the rollover dump truck, the girder and chassis are easy to be stressed unevenly when unloading, so the requirements for the chassis are higher, especially the axle, which is a key part of the chassis load bearing, and is related to the braking, driving and other performance of the vehicle, and must be 100% reliable.
