# Industrial Specification: Reach Stacker

## 1. Technical Definition
A specialized container handling vehicle used in ports and terminals for stacking and transporting shipping containers.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.8-1.2 MPa hydraulic pressure, 0-25 km/h travel speed, -20°C to +50°C ambient temperature**. Failure boundary: **Hydraulic pressure exceeding 1.5 MPa causes seal rupture, structural deformation at 1.8 MPa yield strength, thermal shutdown at 85°C hydraulic fluid temperature**, Mechanism: **Hydraulic fluid viscosity breakdown at 85°C (ASTM D445), seal material (NBR) glass transition at -40°C, steel fatigue at 10^6 cycles (S-N curve for ASTM A36)**.

### 2.1 Analytical Physics Model
Governed by the **Frame Structural Deflection Analysis**:

> **Primary Equation**: $\delta = \frac{5 q L^4}{384 E I}$  
> **Engineering Impact**: Ensures structural stability for multi-stage machines.

| Symbol | Variable Definition | Localized Reference |

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

### Q: What is the typical lifting capacity of a reach stacker?
**A**: Reach stackers typically have lifting capacities ranging from 30 to 50 tons, with some heavy-duty models capable of handling up to 100 tons, depending on the specific model and configuration.

### Q: How does the telescopic boom system work in a reach stacker?
**A**: The telescopic boom uses hydraulic cylinders to extend and retract, allowing the reach stacker to handle containers at various distances without moving the entire vehicle, improving efficiency in crowded port environments.

### Q: What maintenance is required for the hydraulic system?
**A**: Regular hydraulic system maintenance includes checking fluid levels, inspecting hoses and connections for leaks, replacing filters as recommended by the manufacturer, and monitoring system pressure to ensure optimal performance and prevent downtime.
