40' Flat Rack Container Specifications
| Specification | Value |
|---|---|
| Inside Length | 11.832 m |
| Inside Width | 2.228 m |
| Inside Height | 1.981 m |
| Door Width | Not applicable |
| Door Height | Not applicable |
| Enclosed Cubic Capacity | Not applicable |
| Tare Weight | 4,200 kg |
| Maximum Cargo Weight | 40,800 kg |
Door dimensions and enclosed cubic capacity are not applicable because a flat rack has no conventional container doors, full side walls, or enclosed cargo space. Specifications and permitted payloads can vary by equipment manufacturer, carrier, terminal, route, and local transport regulations.
Typical Project Cargo Applications
A 40' flat rack container may be used for steel structures, long industrial machinery, construction equipment, plant components, large vehicles, pipes, cable reels, fabricated units, and heavy cargo that exceeds standard container dimensions. These shipments often form part of a broader project cargo and OOG transport plan involving equipment selection, route review, permits, terminal handling, and inland delivery.
Flat rack movements may also be coordinated through sea freight services and, where specialized inland movement is required, suitable road freight arrangements.
40' Flat Rack vs 20' Flat Rack
The main distinction between a 40' flat rack and a 20' flat rack container is usable floor length and cargo profile. The 20ft version may be more practical for compact and concentrated heavy loads, while the 40ft version provides more space for long machinery, steel structures, fabricated components, and larger project cargo.
The larger unit should not be selected solely because it has more space. Cargo weight distribution, centre of gravity, lifting method, inland road limits, and carrier approval must also be reviewed.
Flat Rack vs Platform Container
A flat rack includes end walls, while a 40' platform container consists only of a reinforced floor structure. Platform equipment offers unrestricted access from the sides and ends, but does not provide the end-wall structure available on a flat rack. The correct choice depends on cargo dimensions, support points, securing design, and loading method.
If the cargo mainly requires loading from above but can remain within a container body, a 40' open top container may be a more suitable option.
Loading, Lashing and Handling Notes
Before booking a 40' flat rack, the cargo length, width, height, gross weight, centre of gravity, lifting points, support locations, and lashing plan should be confirmed. Out-of-gauge cargo may require shipping line approval, additional vessel space, special terminal handling, permits, escorts, or specialized inland trailers.
For equipment selection and project shipment planning, you can contact SASCO or request a shipping quotation by sharing the cargo drawings, dimensions, gross weight, lifting points, origin, destination, and delivery conditions.
Frequently Asked Questions
What cargo is suitable for a 40' flat rack container?
It is suitable for long, heavy, overheight, or overwidth cargo such as industrial machinery, steel structures, plant components, construction equipment, and large vehicles.
When should a 40' flat rack be used instead of a 20' flat rack?
It should be considered when the cargo requires more floor length or consists of long industrial units that cannot be supported properly on a 20ft flat rack.
Is a flat rack suitable for overwidth cargo?
Yes. Its open sides make it suitable for certain overwidth shipments, subject to technical review, securing requirements, carrier approval, and route limitations.
How is cargo secured on a flat rack?
Cargo is secured using an engineered arrangement of suitable lashing, blocking, bracing, and support materials based on its weight, dimensions, centre of gravity, and transport conditions.
