Mineral development plays an important role in China's economic construction. The huge amount of mining has driven the demand for mining trucks. For a long time, in the field of mining vehicles, imported products are in a dominant position, and local models have not been taken seriously. However, this situation is changing.
FAW Jiefang launched a wide-body mining dump truck with an offset cab, which was not only widely recognized by domestic users, but also exported to Kyrgyzstan in May this year. On June 22, China National Heavy Duty Truck Co., Ltd. offset the production line of the HOVA, the wide body mining dump truck, for the 1,000th vehicle this year. The vehicle's domestic market has now exceeded 2000 vehicles. 
With the continuous expansion of open-pit mines in various parts of the country, many small and medium sized mines use ordinary highway dump trucks. These vehicles have poor adaptability and bring about reliability and safety problems. Ordinary road dump trucks have limited bearing capacity and travel on rough roads. The horizontal swing of the vehicle body is large, causing potential safety hazards. Due to the small tonnage of the tonnage and the large number of vehicles required, when the vehicles are operating, the mining area forms a sea of ​​cars, the vehicle density is very high, and the operation efficiency is low, which increases the security risks.
The biased cab wide-body mining dump trucks launched by FAW Jiefang, China National Heavy Duty Truck, Beiben Heavy Duty Truck and others are developed for the characteristics of mines in China. The domestic wide-body mine dump truck absorbs the advantages of the imported large-scale mining vehicle body and bearing capacity. The biased cab is suitable for operation in the mining area, the strength of various components of the car body, and the air filter oil filter adapts to harsh working conditions and conditions. The price has a competitive advantage, higher cost performance.
After the launch of the offset cab wide body mining dump truck, it was welcomed by domestic users for open pit mining and topsoil stripping operations. This kind of dump truck has the advantages of wide body, stability and safety, and low cost of car purchase for large mining vehicles. Compared with ordinary dump trucks, the carrying capacity and reliability are greatly improved. The increase in the load of bicycles can reduce the number of vehicles purchased, reduce the density of vehicles at the site, and improve the safety and efficiency of transportation. It can be said that the offset cab wide body mining dump trucks produced by these local companies can meet the demand for small and medium mines in China for transport vehicles.
In addition to heavy truck companies such as FAW Jiefang and China National Heavy Duty Truck, some domestic construction machinery companies and refitted car companies are also optimistic about this market and have launched a variety of similar mine dump trucks. From the perspective of future development, enterprises such as FAW Jiefang and China National Heavy Duty Truck, which mainly produce heavy trucks, started late but enjoyed more competitive advantages.
The advantages are mainly reflected in the key assembly, product matching and after-sales service.
In respect of the supply of major assemblies and key components, domestic backbone heavy truck companies have advantages in the production of engines, transmissions, beam presses and in-vehicle control systems, which are not available to construction machinery companies and modified car companies. Especially for key components such as the engine, although the supply of ultra-large displacement engines is still weak, 12-liter or lower displacement engines are already mature products for domestic heavy-duty trucks, and the power exceeds 294 kW, which can fully meet the needs of small and medium-sized mines. Dump truck power needs. Due to the large production volume of backbone heavy truck companies, the advantage of spare parts procurement costs is also unmatched by other companies.
In terms of product matching, the domestic backbone heavy truck companies have accumulated a lot of experience after many rounds of product upgrading. Whether they are tapping existing products or matching various types of outsourcing assemblies, the experience of the backbone heavy truck companies are all competitive. The great advantage. In addition, with strong matching ability and advanced management, backbone heavy truck companies also have obvious advantages in the quality control of product production. With the gradual increase of product volume, the high quality brought by large-scale production means that the product has high integrity. The rate and low maintenance costs are also highly valued by mining companies.
Service is the strength of domestic backbone heavy-duty companies, and not to mention the spare parts database all over the country, it is said that the human and material resources of the service stations cannot be compared with other companies. The after-sales service network all over the country not only enables service personnel to go deep into the mining area, but also can timely allocate spare parts resources in the neighboring areas to provide support in case of problems and provide users with timely maintenance services.
While seeing the advantages of heavy-duty trucks, we must also see their shortcomings. First of all, for heavy-duty truck companies, the current development of mining dump trucks, despite their high profits and similarities with existing products, has involved them in this area. Especially for large-tonnage dump trucks with a mass of 100 tons or more and 200 tons or more, domestic heavy-duty truck companies are still blank, and there is still a long way to go before they can truly enter the lucrative large-tonnage mining vehicle market.
Due to the wide-body mining dump trucks currently produced, although the existing heavy truck platform assembly can be used to a large extent, there is still a big difference between the existing axle trucks and some chassis parts and the existing ordinary heavy trucks. Can only rely on external support to make up for their own deficiencies, which is also a factor restricting the heavy truck companies to further develop mine dump trucks.
