Which type of trailer is designed to load cargo ballers onto cargo or military aircraft?

• A. Rollarized Trailer
• B. Flatbed Trailer
• C. Dry Van
• D. Container Trailer

Answer: (A)

The thing being tested here is which trailer type is built to move palletized cargo into aircraft, using rollers to smooth the transfer onto and off of the aircraft. A rollerized trailer has a bed lined with rollers that spin, allowing pallets to be rolled from the ground onto the trailer and then into the aircraft’s cargo hold. This setup minimizes friction and manual effort, making it practical to handle heavy, standard air-cargo pallets (like MIL-STD 463L pallets) in airlift operations. That rolling capability is what makes it specifically suited for loading cargo onto cargo or military aircraft.

Other trailer types don’t fit this purpose. A flatbed has a smooth deck but no rollers, so pallets can’t roll easily onto the trailer or into the aircraft. A dry van is enclosed, which obstructs direct access to the pallets and isn’t designed for rolling cargo into a aircraft. A container trailer is built to haul intermodal containers, not standard palletized air cargo, and again lacks the rolling surface needed for quick air loading.
