A flat rack is a container with a floor and end walls but no roof or side walls, used for cargo that cannot fit or load through a standard box: machinery, vehicles, steel, project pieces. Cargo is lifted or rolled on, then lashed and secured to the rack.
Flat racks keep awkward cargo inside container logistics: the rack locks into cells, stacks, and cranes like any box, while the cargo can exceed the sides or roofline as out-of-gauge, with stowage planned around the overhang. Collapsible end walls let empties fold and stack for repositioning.
Securing is the craft: lashing points, dunnage, and calculations against ship motion. Carriers require securing to standard, and surveyors are commonly involved for heavy pieces.
Flat-rack shipments track by container number like any unit, but their bookings behave differently: special-equipment supply is thin, so confirmation, repositioning, and rollover risk deserve closer watching. In TrackingMCP the equipment code identifies the rack, and the same load, discharge, and gate events mark its journey; OOG pieces add stowage-driven schedule sensitivity.

Open top suits cargo that fits the box footprint but must load by crane from above; flat racks suit width or shape that no closed box accommodates. Overheight alone can go open top; overwidth generally means flat rack.
The shipper is responsible for adequate securing (often via specialist packers), and the carrier can reject insufficient lashing. Requirements follow cargo-securing standards and the carrier’s rules.
