Wherever the KLT boxes have so far been transported manually or with "KLT dollies" as stacks, the Cargo-Liner offers enormous advantages. For example, eight stacks of KLT boxes can be transported simultaneously in the milkrun train, in the case of long travel distances in the material supply, and then separated again in production. The Cargo-Liner is designed in such a way that each stack can be removed or loaded individually and from both sides. Due to the virtual coupling and drawbar system with excellent directional stability, composite transport is possible even in the tightest of spaces.
