# Industrial Specification: Spreader

## 1. Technical Definition
A specialized lifting attachment for container cranes that securely engages with shipping containers for hoisting and transport operations.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **20-40 bar hydraulic pressure, 0.5-2.0 m/s hoisting speed, -25°C to +50°C ambient temperature**. Failure boundary: **Hydraulic pressure exceeding 45 bar causes seal extrusion, hoisting speed above 2.5 m/s induces container oscillation exceeding 15° angle, temperature below -30°C embrittles structural steel (ASTM A36 yield strength reduction to 200 MPa)**, Mechanism: **Fatigue crack propagation in spreader twistlock pins due to cyclic bending stress exceeding 350 MPa at container corners during dynamic loading, following Paris' law with crack growth rate da/dN = C(ΔK)^m where C=1.5e-11, m=3.2**.

### 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 | Spool valve stiction causing asymmetric twistlock actuation | Install 3 μm absolute filtration with differential pressure monitoring at 0.5 bar threshold |
| Corrosion fatigue at spreader beam weld joints in chloride-rich marine environments | 8 | Crack initiation at heat-affected zones reducing section modulus by 40% | Apply duplex stainless steel (UNS S32205) weld overlay with post-weld heat treatment at 1050°C for 30 minutes |
