# Industrial Specification: Quick Coupler (if equipped)

## 1. Technical Definition
A mechanical attachment device that enables rapid connection and disconnection of loader implements without tools.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **15-35 MPa hydraulic pressure, -40°C to 120°C ambient temperature**. Failure boundary: **Hydraulic pressure exceeding 42 MPa causes permanent seal deformation; tensile stress exceeding 620 MPa in locking pins initiates yield**, Mechanism: **Plastic deformation of sealing surfaces due to Hertzian contact stress exceeding material yield strength (σ_y = 620 MPa for 4140 steel); fatigue crack propagation in locking mechanism from cyclic loading at stress intensity factor ΔK &gt; 20 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 |
