# Industrial Specification: Mobile Crane

## 1. Technical Definition
A self-propelled crane mounted on a wheeled or tracked chassis, capable of lifting and moving heavy loads at construction sites, ports, and industrial facilities.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-350 metric tons lifting capacity, 10-120 meters boom length, 0-30 km/h travel speed**. Failure boundary: **Structural failure at 1.5x rated load (525 metric tons for 350t crane), hydraulic system failure at 350 bar pressure, boom buckling at 0.8x Euler critical load**, Mechanism: **Yield strength exceedance in structural steel (S355 steel yields at 355 MPa), hydraulic fluid compressibility failure at 350 bar, boom column instability due to compressive stress exceeding 280 MPa**.

### 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 |
| :--- | :--- | :--- | :--- |
| Hydraulic fluid contamination exceeding ISO 4406 18/16/13 cleanliness level | 8 | Proportional valve spool seizure causing uncontrolled boom movement | Install 3-micron absolute filtration with 0.5 bar differential pressure monitoring |
| Wind load exceeding 20 m/s (72 km/h) during lifting operation | 8 | Dynamic overturning moment exceeding 1.25x static stability moment | Integrate anemometer with automatic load reduction at 15 m/s wind speed |
