# Industrial Specification: Hoist Winch System

## 1. Technical Definition
A mechanical system on a floating crane designed for lifting and lowering heavy loads through controlled cable winding and unwinding.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **15-300 kN cable tension, 0.1-2.0 m/s lifting speed, -20°C to +50°C ambient temperature**. Failure boundary: **Cable tension exceeding 350 kN (70% of cable breaking strength), drum rotation exceeding 25 rpm (gear train resonance frequency), brake lining temperature exceeding 250°C (fade point)**, Mechanism: **Cable yield strength limit (ASTM A586 Grade 270 steel, 1860 MPa ultimate tensile strength), gear train torsional resonance at 25 Hz, brake lining coefficient of friction reduction above 250°C**.

### 2.1 Analytical Physics Model
Governed by the **L10 Bearing Life & Fatigue Model**:

> **Primary Equation**: $L_{10} = (\frac{C}{P})^p$  
> **Engineering Impact**: Predicts mechanical lifecycle before component fatigue.
