The wear-resistant steel used in the mining truck industry is the NM series quenched and tempered special wear-resistant plate, produced according to national standards. It is specifically designed and developed for heavy-duty, high-impact wear conditions in mines. The main components of a mining truck body are: front panel, rear door, floor panel, side panels, and welded parts.
Advantages: High strength, high wear resistance, lightweight body, and excellent wear resistance.
Mainly used in open-pit coal mines and non-ferrous metal mines for crushing stone and earthwork, and large-scale stone quarries with mixed soil and stone.
Product Parameters
The NM400, NM450, and BHG700 models cover all working conditions for mining trucks, including light, medium, and heavy-duty applications.

Frequently Asked Questions
Q: How does the wear resistance of a car body made of ordinary steel plate material compare to that of ordinary steel plate materials in actual use?
A: It has superior wear resistance, significantly extending the service life of the car body. Under the same working conditions, its wear resistance is more than 5 times that of ordinary steel plate materials. This effectively reduces the need for car body repair or replacement.
Q: What are the significant advantages of a car body made of ordinary steel plate material under high impact conditions compared to ordinary steel plate materials?
A: The wear-resistant steel used in the car body, such as wear-resistant 400 material, has a yield strength of over 1000 MPa and a Brinell hardness of over HB350. These properties are more than 3 times that of ordinary steel plate materials, effectively resisting the impact deformation of large rocks and ores.
Q: What are the economic advantages compared to ordinary steel car bodies?
A: Various car body designs combined with high-strength wear-resistant steel can reduce weight by 30%-50% while maintaining strength, achieving higher load efficiency. Although the initial cost is higher than that of ordinary steel car bodies, the later maintenance frequency is lower, the replacement cycle is longer, the attendance rate is higher, and the total life cycle cost is lower.
Q: How does the welding and processing performance compare to that of ordinary material car bodies?
A: The high hardness necessitates more demanding cutting, drilling, welding, and bending processes, requiring specialized equipment and technology.
Q: Are wear-resistant truck bodies suitable for all scenarios?
A: They are primarily used in high-wear, heavy-load environments such as mine dumping, ore, sand and gravel transport, mine spoil backfilling, and off-highway extremely cold regions. They are not recommended for transporting materials such as coal, lightweight particles, short-distance urban transport, or dry, non-wear-resistant, corrosive materials.
