Due to its application in the engineering field, there are various types of dump trucks, which can be classified according to the type of bucket, dumping method, and form of lifting mechanism. Let's talk about the classification of heavy-duty dump trucks according to their working conditions.
● Grading of load capacity of dump trucks, the main force of infrastructure and mining
The road dump trucks are classified according to the maximum total mass, and can be divided into light, medium and heavy duty. Among them, heavy duty dump trucks are generally models with rear double axles (6X4 and 8X4), which are commonly used in urban muck, engineering construction, and mining. The main model of transportation, etc.
For highway heavy-duty dump trucks, it can be subdivided according to the working conditions of the vehicle, because under different working conditions, the configuration of the vehicle, especially the load-bearing system, will be different.
The higher the load level, the higher the configuration of the vehicle power system and load-bearing system. In terms of power, it goes without saying that the power generation is naturally more important, and the transmission system is more important. The large speed ratio of the gearbox and rear axle is matched, and even the use of wheel reduction axles is the key to heavy-duty transportation. Materials and structures, such as multi-layer composites and bolted connections, the number of suspension leaf springs and riding bolts, etc., are relatively basic methods of discrimination.
● The naming of heavy dump can determine the working condition level
If this does not give you a clear understanding of vehicle positioning, you can look at how manufacturers are segmented. The naming of heavy-duty dump trucks according to the working conditions can refer to the following figure (due to the lack of a unified standard, the naming methods of various manufacturers will be different, but they are also similar).
6X4 is mainly affected by road conditions, and is divided into mining engineering type, urban construction slag type, and road transportation type according to road conditions;
8X4 is mainly affected by the load, and is divided into heavy-duty type, compound type and standard type according to the load.
6X4 Urban Construction Muck Dump Truck
The road heavy-duty dump truck has a large weight, so it has higher requirements on the bearing capacity of the frame, suspension and rear axle. The road conditions of loading and unloading locations are bad, such as mines, construction sites, etc., and the vehicles are heavily loaded on uneven roads, which is a great test for the reliability of the axles and frames.

● Choose a car according to road conditions 6X4 also has high bearing capacity
Generally speaking, the more axles of the vehicle, the greater the bearing capacity. However, like mining engineering, although the demand for vehicle bearing capacity is relatively high, under severe road conditions, 8X4 vehicles are not flexible, so more 6X4 vehicles are used. After the suspension, it is no less than a normal 8X4 vehicle in terms of carrying capacity.
