# Industrial Specification: Safety Hook

## 1. Technical Definition
A safety-critical attachment device for securing loads on jib cranes.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **2.5-25 kN working load limit, -40°C to +120°C temperature range**. Failure boundary: **Material yield strength threshold at 355 MPa (S355 structural steel), latch engagement force below 150 N**, Mechanism: **Plastic deformation due to stress concentration at hook throat radius (minimum 3:1 D/d ratio violation), fatigue crack propagation from cyclic loading exceeding 1×10⁶ cycles at 0.7×WLL**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Corrosion-induced material thinning exceeding 10% cross-sectional area loss | 8 | Hook bending failure under dynamic loading at 1.5×WLL | Hot-dip galvanizing to 85μm minimum coating thickness with ASTM A123 compliance |
| Latch spring relaxation below 60% original preload after 5000 actuation cycles | 8 | Unintentional latch disengagement during load swing at 15° deflection angle | Double-spring redundant latch mechanism with 316 stainless steel springs meeting EN 1677-1 standards |
