PartialFlatbed—also referred to as LTL Flatbed, shared flatbed load, or oversize LTL freight—is a method of combining multiple shipments onto a single open-deck trailer. It is designed for freight that requires flatbed or step deck equipment but does not utilize the full capacity of a trailer.

This model applies when a shipment only occupies a portion of the trailer’s available load factor. Load factor refers to how much of the trailer is used, either by physical space (deck dimensions) or by allowable weight within legal limits. Instead of moving partially empty, the remaining capacity is utilized by other compatible shipments.

To operate effectively, shipments must be carefully coordinated before transit. This involves aligning several key factors such as routing, timing and compatibility.

Proper planning ensures that all shipments remain within legal load limits while maintaining safe loading practices.

By consolidating multiple partial shipments onto one trailer, this approach reduces unused capacity and creates a more efficient and sustainable way to transport open-deck freight.

From an operational standpoint, a PartialFlatbed shipment moves similarly to a full truckload. A single carrier is assigned to the move, handling pickups and deliveries along a planned route.

The key difference is that the trailer is shared. Two to three shipments are loaded, secured, and transported together, with each shipment occupying a defined portion of the trailer based on its size and weight.
