As a special vehicle with a large market share, the dump semi-trailer is widely used in the transportation of loose goods such as sand, gravel, soil, and coal. Its loading compartment can automatically tip over at a certain angle during unloading, which greatly saves unloading time. And labor, shorten the transportation cycle, improve production efficiency.
At present, the self-unloading semi-trailers on the market are mainly divided into two types: rear-turning self-unloading and side-turning self-unloading. Which one is more safe for cargo transportation?
The main difference between a rear-turning semi-trailer and a side-turning semi-trailer:
- Site requirements: In general, side dump trucks require the unloading site to be large, wide, and flat, while rear dump trucks do not have too many requirements for the width of the site. It only needs to be flat and unobstructed, which is relatively free Some.
- Model requirements: side dump trucks are generally used for heavy-duty vehicles or trailers with a cargo compartment length greater than 9.6 meters, while rear dump trucks are more commonly used for standard load or short wheelbase vehicles.
- Lifting form: The lifting height of the side-turning dump truck is low, so the center of gravity of the body is relatively low when unloading, but also because of its lifting method, the beam is prone to uneven force when unloading; The lifting height of the tipper dump truck is relatively large, and the center of gravity of the vehicle tends to be biased towards the rear when unloading, causing head tilt, especially when unloading from uphill to downhill.
Both types of self-unloading semi-trailers are prone to instability if they are not well controlled when unloading. However, the rollover dump truck is generally equipped with a shift lever, so this kind of rollover accident can be reduced to a certain extent, but it cannot be completely avoided, and strict and standardized operation is required.
In general, the dump truck semi-trailer transports heavy goods, so the requirements for the vehicle chassis are higher. Especially the axle assembly, which is not only the key component of the chassis load bearing, but also related to the braking and driving performance of the vehicle, must be 100% reliable. There are many axle brands on the market, which one is worth buying?
