# Industrial Specification: Vertical Column

## 1. Technical Definition
The vertical structural support component of a treatment couch that provides height adjustment and stability.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.8-1.2 m vertical travel, 150-250 kg static load capacity, 0.05-0.15 mm/m straightness tolerance**. Failure boundary: **Buckling failure at 300 kg compressive load (Euler critical load), yield failure at 350 MPa stress (AISI 304 stainless steel), 0.25 mm/m permanent deflection**, Mechanism: **Euler buckling instability under compressive loading (critical load P_cr = π²EI/L²), plastic yielding at σ_y = 350 MPa, fatigue crack propagation at stress intensity factor K_I &gt; 30 MPa√m**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.

| Symbol | Variable Definition | Localized Reference |

**Downstream Applications**: Medical Treatment Couch, Physical Therapy Table, Diagnostic Imaging Bed  

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are available for the vertical column?
**A**: Our vertical columns are manufactured using either 304 stainless steel for maximum corrosion resistance or lightweight aluminum alloy for applications requiring reduced weight while maintaining structural integrity.

### Q: How does the vertical column provide height adjustment?
**A**: The column utilizes a precision lead screw mechanism working in conjunction with linear guide rails, allowing smooth, controlled vertical movement with locking positions for secure patient positioning.

### Q: What components are included in the vertical column assembly?
**A**: Each vertical column assembly includes guide rails for smooth movement, a lead screw for precise height adjustment, and a mounting bracket for secure attachment to the treatment couch frame.
