Flat Rack Containers are specialized types of shipping containers designed for transporting heavy or oversized cargo that doesn’t fit in standard enclosed containers.
These containers have a rigid frame structure without solid walls, allowing for easier loading, unloading, and securing of irregularly shaped items like machinery, vehicles, pipes, or construction materials.
Key Features of Frame Containers:
1. Open Frame Structure: Unlike traditional containers, frame boxes don’t have side walls, a roof, or sometimes even a floor, depending on the design. This open structure allows for the easy handling of large and irregularly shaped goods.
2. Heavy-Duty Build: These containers are built with a strong steel frame that can handle heavy loads and withstand harsh environmental conditions during transportation.
3. Multiple Sizes: Frame containers are available in standard shipping container sizes, such as 20 feet, 40 feet, and sometimes larger, allowing them to be used in combination with regular containers for intermodal transport.
Here’s a table with the dimensions of different sizes of Flat Rack Containers.
| Flat Rack Container Size | Internal Length (mm) | Internal Width (mm) | Internal Height (mm) | Max Gross Weight (kg) | Tare Weight (kg) | Max Payload (kg) |
|---|---|---|---|---|---|---|
| 20ft Flat Rack | 5,940 | 2,350 | 2,330 | 34,000 | 2,700 | 31,300 |
| 40ft Flat Rack | 11,720 | 2,440 | 1,955 | 45,000 | 5,920 | 39,080 |
| 40ft High Cube Flat Rack | 11,650 | 2,400 | 2,120 | 45,000 | 5,920 | 39,080 |
4. Easy Loading/Unloading:
Due to the open nature of the frame container, cranes or other heavy-duty equipment can easily load and unload oversized items without obstruction.
5. Applications:
– Transporting large industrial machinery
– Shipping vehicles, trucks, or buses
– Construction materials like steel beams or precast concrete
– Pipes, cables, or other large structural components
6. Flexible Securing: Since these containers have no solid walls, cargo can be secured using chains, straps, or specialized braces attached directly to the frame to prevent movement during transit.
Frame containers are widely used in industries like construction, mining, and oil and gas, where bulky or heavy equipment and materials need to be moved across long distances.
