Which self-unloading semi-trailers can still be used in compliance?
Flat-bed dump trucks are more common in the transportation of high-density bulk cargo such as sand and gravel. When they go to the household, they are only in the form of a flatbed. After the household is installed, a cargo compartment is added to increase the cargo loading capacity.
Compared with ordinary standard dump trucks, flat-bed dump trucks have a larger loading capacity, so they have become "one of the main models for overloaded transportation".
After the modification of GB7258, it is stipulated that the flat plate of flat-bed trucks should not be designed with pile insertion structures, grooves, container locks and other devices, and the loading parts of flat-bed trucks and warehouse-grid trucks should not have lifting functions Or adopt self-unloading structure.
That is to say, after the flatbed truck is registered, it is not allowed to install locks or install a hydraulic lifting mechanism without permission. The flatbed truck is a flatbed truck, and the dump truck is a dump truck. Otherwise, a fine will be imposed upon discovery.
What are the compliant self-unloading semi-trailers?
1. Self-unloading container semi-trailer
This type of vehicle is mainly used to transport containers, and its appearance is almost exactly the same as that of a flat-bed dump truck. In fact, the flat-bed dump truck is developed from this type of vehicle.
The difference is that the chassis of the container semi-trailer is a skeleton structure, while the flat-bed dump truck is a flat structure. Since the regulations only restrict flat-bed dump trucks, container dump trucks are still in compliance.
2. Standard rear tipping semi-trailer
The total length of this type of vehicle is generally about 8-10m, the inner diameter width is about 2.45m, and the outer diameter width can be up to 2.55m, but the height of the fence is only 0.6m, so the maximum volume of the cargo compartment can reach about 14.5 square meters.
For car owners who are used to flat-bed dumpers, the loading capacity of this model is indeed much smaller, but this model can be used on the road in compliance with the regulations, and it will not face the risk of being investigated and dealt with like flat-bed dumpers. In addition, for standard-load transportation, tractors with lower horsepower can be selected, which can reduce the overall cost of vehicles to a certain extent.
3. Standard rollover dump semi-trailer
When the side-turning model is unloading, the lifting height of the compartment is lower than that of the rear-turning type, so it can be up to 13m in length, 2.55m in outer width, and 0.6m in height of the railing, compared with the standard rear-turning type , its transportation volume will obviously be larger. In addition, the lift height is low, and the stability when unloading will be better.
It is worth noting that in order to meet the market demand, some manufacturers cut off the top of the tank body of the lift-type powder transport semi-trailer and refit the tail into the style of a dump truck. Such models are also illegal, no matter from the perspective of regulations, From the perspective of safety or the general environment of the industry, compliant transportation is the general trend, and car owners must pay attention to following the general laws of industry development when choosing.
The working conditions of the tipper semi-trailer are complex, and its design, materials, craftsmanship, and accessories must be safe and reliable. For example, the trailer axle, as the key component of the dump truck’s load-bearing, should try to choose those that have independent factories and have the ability to customize Brands with production capacity should have entered the market for a long enough time and have been fully verified by the market. Only such brands are more reliable to use.
