The materials of dump trucks mainly include the following:
Aluminum alloy: Aluminum alloy materials are widely used in the manufacture of dump truck compartments, mainly in the form of cast alloys or deformed aluminum alloys. Deformed aluminum alloys include aluminum alloy plates and strips, extruded profiles and forged profiles. Aluminum alloy materials are lightweight and high-strength, suitable for application scenarios where the weight of the vehicle needs to be reduced.
Steel: Steel is another common raw material for dump truck compartments, especially Q345B grade steel, which has a relatively low price and high strength and load-bearing capacity, suitable for dump truck compartments that need to carry heavier items. However, steel has poor corrosion resistance and requires regular maintenance.
In addition, high-strength steel is also widely used in lightweight solutions, which can achieve lightweight goals while ensuring vehicle reliability and safety.
Fiberglass (glass fiber reinforced plastic FRP): Dump truck compartments made of fiberglass are lightweight, high-strength, durable and easy to maintain, and are often used in chemical and food fields. But its cost is high and the processing technology is complicated.
Stainless steel: Stainless steel dump trucks are mainly used to transport corrosive goods, such as sea salt, sea sand and certain chemical materials. Stainless steel has high strength and corrosion resistance. Key components such as bottom plates, columns, side beams and box plates are made of stainless steel, while other parts are made of traditional steel to balance performance and cost.
High-strength wear-resistant steel: Such as Lian Steel NM450 material and LG700XL material. These materials have high strength and wear resistance and are widely used in large plates and rib structures of dump truck compartments, which can improve the strength and durability of the compartment.
