the pallet-like vehicles are merely trailers that are towed/moved with small tractors......this affords the ease of moving the helicopter in and out of a hangar without having to equip them with wheels to roll them in and out, lots easier and quicker.
as for getting it onto the trailer, they simply land the helicopter onto the trailer when returning to its base
