Modular Fixed Container Carrying Semitrailer, EU rules, for transport of Containers and/or Swap Bodies of various type and measures.
The semitrailer is equipped with a longitudinal sliding system of twist-locks arms that permits always to place the transported units in a perfectly balanced position during the road transport, with a correct distribution of weights over the axles and on hinge-pin.
For the tipping operations, the container slides up to the back end of the chassis (moved by hydraulic cylinder put into action with a self-contained electromotor). At the end of the operations, the container is again replaced in the balanced position for the road transportation.
For the loading/unloading operations, the container slides up to the back end of the chassis (moved by hydraulic cylinder put into action with a self-contained electromotor), so that a direct access to the cargoes is obtained also with a traditional transpallet. At the end of the operations, the container is again replaced in the balanced position for the road transportation.

Comparison between Modular Fixed Container Carrying Semitrailers and "extensible" or "conventional" types.
| Modular | Extensible | Conventional |
|---|---|---|
| It can transport containers of various lengths and permit the loading and unloading operations at rear back end of the semitrailer, with easy access to the inside of containers. | It can transport containers of various lengths and permit the loading and unloading operations at rear back end of the semitrailer, with easy access to the inside of containers. | It can carry containers of various lengths, but the access to shorter containers require extensible platforms as such containers are not positioned on the rear back end of the frame. |
| The road circulation is always in complete safety and in full compliance with the road regulations: no need to travel with unbalanced containers on the back end of the semitrailer. In fact, the shorter containers are placed centrally on the frame and only at the moment of loading and unloading operations they are shifted toward the rear back end of the semitrailer. | Even while carrying a 20' container, the semitrailer run without a proper weight distribution: in fact most of the weight of the container rests directly on to the three axles, while the fifth wheel weight is significantly lower. In other words if you want the proper balance of masses, the total mass of the trailer is reduced and consequently so is the maximum mass transport. | If the access on the rear back end of the semitrailer is required, the shorter containers must be placed with alignment to the rear of the vehicle, causing an imbalance in the distribution of weights that, besides affecting the safety, it is prohibited by the road regulations. |
| The traslation is absolutely autonomous and independent respect the tractor and the operation is fully controlled by an electronic sequence of required actions. Maximum safety and ease of use: the Operator simply by pressing of buttons on a single keyboard move the shifters arms in the correct position depending on the length of the container. That's all. | To extend or short the semitrailer, this must be hooked to the tractor.Also the rear of the semitrailer must be manually extended or retracted and it is still necessary that the Operator positions (by a process of tripping, slipping, introduction and re-coupling) all twist-lock needed depending on the length of the container. | Not Applicable. |
| The tare of the semitrailer is almost similar to that of a comparable conventional semitrailer. | Normally the tare of such semitrailers is about 1000÷1500 Kgs more than the Modular Semitrailers by CHIAVETTA | If the tare is the same, why waive the possibility to carry and shift containers of different lengths? |
| The frame is "one piece", providing both a structural strength of the semitrailer and an increased security. Moreover any laborious steps to adapt the chassis of the semitrailer to the length of the transported containers are eliminated. | Experience teaches that everything that moves, eventually deteriorates or breaks. Moreover, the extensible semitrailer generally requires constant maintenance, especially for the lubrication of parts movingbetween them. | Not Applicable. |
| The tire wear is almost similar to that of a conventional semitrailer. | The average duration of tires is significantly reduced, for two basic reasons, namely: A) When a 20' container is carried, the semitrailer does not have a proper balance of weight. B) Also travelling in a straight line, because of the inevitable "games" that are created between the two spars supporting (or in coupling of the one central spar, depending on the model) the wheels do not maintain the correct alignment (imbalance both the camber and the convergence). | Not Applicable. |
| Operator and road user safety is absolute. There is no the danger of "losing" some piece of the semitrailer because there is nothing to engage or disengage: simply just press the buttons (also in suits....). | Disengages, engages, replace, get out of tractor, testing, back into the tractor, go back, go ahead, take the pins, reinsert the pins ... | Not Applicable. |
With only one vehicle (and therefore with a single investment cost) the needs of transporting containers of various lengths are met Ultimately that is the equation: More Containers = One Semitrailer. One Semitrailer = "Flexible" investment. | Even for extensible semitrailer the concept of flexible investment is applicable. But maintenance costs are the same? And the Drivers are really happy? | Implies the need to equip its fleet of how many units are the lengths of the containers to carry. Ultimately that is the equation: More Containers = More Semitrailers. More Semitrailers = "Rigid" investment. |
