# Industrial Specification: Heavy Forklift

## 1. Technical Definition
A heavy-duty industrial vehicle designed for lifting, moving, and stacking large loads in manufacturing, warehousing, and construction environments.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **2.5-4.5 MPa hydraulic pressure, 0-15° grade incline, -20°C to 50°C ambient temperature**. Failure boundary: **Hydraulic pressure exceeding 5.2 MPa causes seal extrusion, mast deflection exceeding 0.15% of height causes structural buckling, continuous operation at 55°C ambient causes thermal runaway in power electronics**, Mechanism: **Hydraulic seal failure occurs via extrusion when pressure differential exceeds seal material yield strength (EPDM rubber: 10-15 MPa tensile), mast buckling follows Euler's column formula with effective length factor K=2.0 for cantilever loading, power electronics thermal failure follows Arrhenius equation with activation energy 0.7 eV for silicon devices**.

### 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.
