Component Specifications

Definition
The floor is the primary load-bearing surface of a dump body, designed to withstand the weight and impact of bulk materials during loading, transport, and controlled discharge. It forms the bottom enclosure of the container and must resist abrasion, corrosion, and deformation under cyclic loading conditions typical in mining, construction, and material handling applications.
Working Principle
The floor provides a continuous, rigid surface that distributes payload weight evenly across the dump body's structural framework. During dumping operations, it facilitates material flow through controlled geometry and surface properties, while maintaining structural integrity through welded or bolted connections to sidewalls, hoppers, and reinforcement members.
Materials
High-strength abrasion-resistant steel (AR400 or AR500 grade), typically 6-12mm thickness. Alternative materials include Hardox wear plates or aluminum alloys for weight reduction in specific applications.
Technical Parameters
  • Thickness 8-10mm standard
  • Material Grade AR450
  • Standard Width 2400-3000mm
  • Surface Hardness 400-500 HBW
  • Tensile Strength 1400-1800 MPa
  • Connection Method Continuous weld with reinforcement plates
Standards
ISO 5817, DIN EN 10025, ASTM A514

Frequently Asked Questions

What is the typical lifespan of a dump body floor?

With proper AR450 steel construction, a dump body floor typically lasts 3-5 years in severe mining applications or 5-8 years in general construction, depending on material abrasiveness and maintenance.

Can dump body floors be repaired or replaced?

Yes, worn sections can be patched with weld-on wear plates, but complete replacement is recommended when wear exceeds 50% of original thickness or when multiple repairs compromise structural integrity.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
