# Industrial Specification: Gantry Crane

## 1. Technical Definition
A large crane with a horizontal beam supported by two or more legs running on fixed rails or ground tracks.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **10-100 kN lifting capacity, 5-50 m span, 0.1-2.0 m/s hoisting speed, 0.5-3.0 m/s trolley speed**. Failure boundary: **Structural failure at 150% rated load (150 kN for 100 kN crane), rail deflection exceeding 1/500 of span (100 mm for 50 m span), motor thermal overload at 155°C winding temperature**, Mechanism: **Euler buckling in compression members at critical load, plastic hinge formation in main girder at yield stress (typically 235 MPa for S235 steel), bearing seizure due to lubricant breakdown at 120°C**.

### 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 |
| :--- | :--- | :--- |
| q | Uniform Load | Engineering Constant |
| E | Elastic Modulus | Engineering Constant |
| I | Moment of Inertia | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Hoist motor brake solenoid coil insulation breakdown at 500 V dielectric strength | 8 | Uncontrolled load descent at 9.81 m/s² gravitational acceleration | Dual redundant spring-applied brakes with 200% holding torque margin |
| Rail joint misalignment exceeding 3 mm vertical gap | 8 | Wheel flange climb derailment at 0.5 m/s lateral force | Continuous welded rail with 1 mm maximum joint tolerance and laser alignment monitoring |
