When industrial machinery, such as presses or other heavy equipment, needs to be housed in a container, a standard shipping container is often insufficient. These containers must act not only as enclosures but also as structural foundations, capable of handling dynamic loads, vibrations, and heavy operational stress.
This guide provides detailed technical recommendations, including floor reinforcement, steel specifications, vibration control, and roof/wall layouts, helping engineers and clients make informed decisions.
1. Internal and External Dimensions
All dimensions refer to the usable internal space. External dimensions must respect standard transport limits, e.g., 40’ GP container: 12,192 × 2,438 × 2,896 mm.
| Parameter | Requirement | Notes |
|---|---|---|
| Length | 12.0 m | Internal usable length |
| Width | 3.0 m | Internal usable width |
| Height | 3.20 m | Internal usable height |
| Access | Single door, front wall | Must allow equipment and personnel entry |
| Roof/Walls | Removable/demountable | Facilitates installation and maintenance |
Feasibility Note: If the required internal dimensions exceed transport limitations, manufacturers can propose maximum achievable dimensions.
2. Floor Reinforcement Design
The floor must handle static weight and dynamic operational loads. Proper design ensures safety, reduces wear, and minimizes vibration.
Key Features:
- 28 C-shaped beams as the base frame
- Cross and longitudinal beams added depending on machine weight
- Floor plates 10–15 mm steel for heavy loads
Table: Floor Reinforcement by Machine Weight
| Machine Weight (kg) | Base Frame | Additional Beams | Floor Plate Thickness |
|---|---|---|---|
| <5,000 | 28 beams | None | 10 mm |
| 5,000–10,000 | 28 beams | Cross beams | 12 mm |
| 10,000–20,000 | 28 beams | Cross + longitudinal | 15 mm |
| >20,000 | Custom frame | Multiple reinforcements | 15–20 mm |

Tip: The machine footprint should align with reinforced beams for optimal load distribution.
3. Vibration Control
Machines such as presses generate vibrations that can damage both machinery and the container. Anti-vibration pads are critical.
Parameter Specification Notes
| Parameter | Specification | Notes |
|---|---|---|
| Material | Rubber, Neoprene, Polyurethane | High damping, durable |
| Position | Perimeter + machine mounting points | Exact positions based on machine layout |
| Thickness | 20–50 mm depending on load | Heavier machines require thicker pads |
| Fixing Method | Bolted or welded | Matches machine installation type |
4. Roof and Wall Design
Handling a 12m roof as a single panel is impractical. Segmentation and demountable walls are essential.
Component Recommendation Notes
| Component | Specification | Notes |
|---|---|---|
| Roof Sections | 6m + 6m or 8m + 4m | Easier to lift & install |
| Wall Panels | Removable/demountable | Full access for installation/maintenance |
| Door | Single, front wall | Equipment and personnel entry |
| Roof Material | Steel plate 8–12 mm | Matches container structural strength |
| Fixing | Bolted or welded | Stability and safety during operation |
5. Installation and Fixing Options
Welding: Permanent and strong, ideal for high-vibration machinery.
Bolting: Flexible, allows easy maintenance or replacement.
The fixing method should match the dynamic load profile and maintenance plan.
6. Maximum Machine Weight and Reinforcement Options
| Machine Weight (kg) | Floor Reinforcement | Notes |
|---|---|---|
| < 5,000 | Standard 28-beam base frame | Suitable for light presses |
| 5,000 – 10,000 | Add cross beams & thicker floor plate | Medium presses |
| 10,000 – 20,000 | Cross + longitudinal beams, thicker plates | Heavy presses |
| > 20,000 | Custom reinforced frame + multiple anti-vibration pads | Requires engineering approval |
7. RFP Preparation Checklist
To ensure an accurate quotation, include:
- Internal dimensions (L × W × H)
- Total machine weight
- Machine footprint & fixing positions
- Dynamic load profile
- Roof/wall access requirements
- Transport constraints
- Installation method (bolted/welded)
Tip: Include CAD drawings or photos of the machine for precise planning.
8. Conclusion
A specialized container for industrial machinery requires careful engineering, reinforced flooring, vibration control, and flexible access.
