# Industrial Specification: Dump Body

## 1. Technical Definition
The main cargo-carrying container of a dump truck that tilts to unload materials.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-70° tilt angle, 0-50 MPa hydraulic pressure, -40°C to 120°C ambient temperature**. Failure boundary: **Material yield strength exceedance at 550 MPa for structural steel, 60° tilt angle causing center of gravity shift beyond wheelbase, hydraulic cylinder pressure exceeding 55 MPa**, Mechanism: **High-cycle fatigue from cyclic loading at stress concentrations near hinge points, plastic deformation from overloading beyond yield strength, stress corrosion cracking in weld zones from chloride exposure**.

### 2.1 Analytical Physics Model
Governed by the **Frame Structural Deflection Analysis**:

> **Primary Equation**: $\delta = \frac{5 q L^4}{384 E I}$  
> **Engineering Impact**: Ensures structural stability for multi-stage machines.

| Symbol | Variable Definition | Localized Reference |

- **Caution**: 

### Q: What materials are used in dump body construction?
**A**: Our dump bodies are constructed from high-strength steel for maximum durability and load-bearing capacity in demanding industrial applications.

### Q: What are the main components of a dump body?
**A**: Key components include the floor, headboard, side walls, tailgate, hinge pins &amp; brackets, and hoist cylinder mounting brackets for complete functionality.

### Q: How does a dump body unload materials?
**A**: The dump body tilts hydraulically using the hoist cylinder system, allowing for efficient unloading of bulk materials like gravel, sand, and construction debris.
