# Industrial Specification: Gantry Frame

## 1. Technical Definition
The primary structural framework of a gantry crane that supports the hoist and trolley system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-150 MPa compressive stress, 0-80 MPa tensile stress, 0-50 MPa shear stress**. Failure boundary: **Yield strength of ASTM A572 Grade 50 steel at 345 MPa tensile stress, 250 MPa compressive stress, or 200 MPa shear stress**, Mechanism: **Plastic deformation due to von Mises stress exceeding yield criterion under combined loading from hoist capacity (e.g., 50-ton load) and dynamic factors (1.25-1.5)**.

### 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.
