# Industrial Specification: Tower Crane

## 1. Technical Definition
A tall, fixed crane used for lifting and moving heavy materials on construction sites.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.8-1.2 MPa hydraulic pressure, 380-415 V AC supply voltage, -20°C to +40°C ambient temperature**. Failure boundary: **Structural failure occurs at 1.8 MPa hydraulic pressure (180% of nominal), electrical failure at 480 V AC (126% of nominal), mechanical failure at -30°C (brittle fracture threshold)**, Mechanism: **Yield strength exceedance in structural steel (S355 grade, 355 MPa yield) at 1.8 MPa hydraulic pressure, insulation breakdown in motor windings at 480 V AC due to dielectric strength limits, ductile-to-brittle transition in steel at -30°C**.

### 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.

- **Caution**: 
- **Caution**: 

### Q: What is the maximum lifting capacity of this tower crane?
**A**: The maximum lifting capacity varies by model but typically ranges from 5 to over 50 metric tons, depending on jib length and configuration.

### Q: How is the tower crane powered on construction sites?
**A**: Our tower cranes typically operate on standard industrial power supplies (380-480 volts, 3-phase) with options for diesel generators in remote locations.

### Q: What safety features are included in the operator's cab?
**A**: The operator's cab includes ergonomic controls, panoramic visibility, load moment indicators, anti-collision systems, and emergency stop functions for safe operation.
