How a 20' Flatrack Collapsible is used
A twenty-foot flatrack whose end walls fold flat onto the deck when the unit is empty.
Folded units stack several high in the space one fixed flatrack would take, which cuts the cost of moving empty equipment. Carriers therefore often offer collapsible flatracks ahead of fixed-end units, and they tend to be easier to find.
Usable length and width are a little tighter than the fixed-end equivalent, because the hinge takes room at each end.
Cargo it suits
How the box is made
- A steel deck on a reinforced underframe, rated for a heavy point load rather than a load spread evenly.
- End walls only. They are fixed on a standard unit and hinged on a collapsible one. There are no side walls and no roof.
- Lashing rings sit in the side rails, often with pockets for stanchions.
- Corner castings sit in the standard ISO positions, so the unit handles and stacks like any other container.
- End walls hinge at deck level and lock upright in use. They fold inward so empty units nest for stacking.
- A steel frame with a softwood floor. The end walls are rated for cargo lashings and for stacking loads.
- Lashing rings sit in the side rails, the corner posts and the floor, rated to 2,000 kg on 20 ft units.
- Some 20 ft units have forklift pockets, and stanchions can be fitted where the cargo needs uprights.
Why shippers choose it
- Takes cargo wider and taller than any closed unit can accept.
- The payload rating is high, which suits dense cargo such as steel, stone and machinery.
- Loading can come from the side or from above, so the door opening never limits the piece.
Check these before you book
- Cargo is fully open to weather and spray, and it usually needs wrapping or sheeting.
- Lashing and weight distribution are worked out for each shipment. Over-width or over-height cargo also limits what can be stowed next to it.
