# Industrial Specification: Straddle Carrier

## 1. Technical Definition
A specialized vehicle used for lifting and transporting shipping containers in port terminals and intermodal yards.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.8-1.2 MPa hydraulic pressure, 0-25 km/h travel speed, -20°C to +50°C ambient temperature**. Failure boundary: **Hydraulic pressure exceeding 1.5 MPa causes seal rupture, structural deflection exceeding 15 mm at spreader tips causes container drop, wheel slip angle exceeding 8° causes tipping**, Mechanism: **Hydraulic fluid compressibility (bulk modulus 1.4 GPa) causing pressure spikes, Euler buckling in telescopic boom sections (critical load 450 kN), Coulomb friction coefficient (μ=0.6) between tires and pavement determining lateral stability**.

### 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.
