A wheelless steel platform used to transport paper reels on ro-ro forest products. Terminal tractors use lift-trailers to handle it. The 12.2m long cassette has a maximum capacity of 80t, but normally carries 45/60t. Paper reels are pre-lashed at the paper mill onto the cassette eliminating on-board lashings. Cassette can also be used for container handling and two 40-ft units can be carried on top of each other. See also Rolux wheelless cassette system.
