... 12 NCFRP Report 20 | Guidebook for Assessing Evolving International Container Chassis Supply Models | 12 Chassis Supply Chain Operations Key Messages The terminal storage function can be "grounded," which requires stacking containers, or "wheeled" with containers stored on chassis. Wh eeled operations, more typical at inland rail terminals, usually transfer containers to draymen with one lift, but require a larger fleet of chassis, more land to store chassis, and containers on chassis.

With respect to the mo vement of containerized imports and exports, Figure 2-1 highlights the transportation moves in which the chassis is involved (orange arrows)

... 14 NCFRP Report 20 | Guidebook for Assessing Evolving International Container Chassis Supply Model s | 14 2.2 Chassis Operations at Terminals Conventionally, the ocean carrier chassis supply model required the pickup/drop off of a ch assis or chassis container for every import container transported, in-gate inspections upon the motor carrier returning the chassis, and the storage, maintenance, and repair of chassis within the terminal gate. As with the evol ution of chassis supply models, this is no longer always the ca se.

For example, a large marine terminal may unload 3,000 containers onto chassis from each of the three vessels calling in a week, while a large rail terminal unloads 240 containers to chassis for each of the ten inbound trains a day.
