# Industrial Specification: Trolley Frame

## 1. Technical Definition
The structural framework that forms the main body of a trolley, providing support and shape.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-1500 kg load capacity, -40°C to 80°C temperature range, 0-2.5 m/s velocity**. Failure boundary: **Yield stress of 250 MPa for structural steel, 1.5 mm permanent deformation threshold, 10⁷ fatigue cycles at 500 MPa stress amplitude**, Mechanism: **High-cycle fatigue from cyclic bending stresses exceeding S-N curve endurance limit, Euler buckling instability at critical load of 2000 kg for 2m unsupported length**.

### 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.

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

### Q: What materials are best for trolley frames in corrosive environments?
**A**: Stainless steel is ideal for corrosive environments due to its rust resistance. Aluminum alloy also offers good corrosion resistance with lighter weight, while steel frames require protective coatings for similar conditions.

### Q: How do I choose between steel and aluminum alloy trolley frames?
**A**: Choose steel for maximum strength and load capacity at lower cost; opt for aluminum alloy when weight reduction is critical, as it's lighter while still durable. Consider your load requirements and mobility needs.

### Q: Can trolley frames be customized for specific industrial applications?
**A**: Yes, trolley frames can be customized in dimensions, material thickness, and BOM components like cross members, uprights, and wheel brackets to match exact load capacities, space constraints, and usage environments.
