The Caps are designed aerodynamical and can be loaded with two euro-pallets each according to CCG 1. Trailing wheels take on the function of bearing, lateral guide rollers keep the Caps on track.
The drive is provided electrically by the wheels. In this connection three-phase asynchronous motors supplied by frequency converters come into operation. This concept is marked by a robust construction, low energy consumption, low initial costs as well as a long life with a low need for maintenance. In addition the chosen drive concept provides optimum traction in connection with high operation security.
If the demand for transport increases (scheme 1) the single Caps group into collectives running close to each other.
In connection with the individual control of the capsules the small distance of 2 m requires a novel branching system which makes it possible to discharge the single Caps out of a collective without speed reduction. Thus a constant flow of transport is ensured.
In this connection the vehicle steers the process of turning off. The swithes themselves are complete passive elements. The driving direction is chosen by the vehicle before entering the branching area according to the final destination programmed inside the on-board computer.
Operating safety
An elementary criterion of CargoCap represents the operating safety. The Caps possess, beneath the electric service breaking device, a second independent brake unit. The equipment with several engines ensures that in case of a defect the way can be continued with reduced performance at least to the next station. In addition the fronts of the Caps are equipped with collision units which allow to push broken down vehicles out of the transportation pipe.
Sustainability
During the construction of the mechanic as well as the electric components it was emphasized that inevitable wear and tear always occurs on the vehicle but not on the track. So wearing parts can be replaced easier, faster and cheaper.
One of the remarkable features of the CargoCap-concept is its frankness towards technical innovations.
Control technique
An essential aspect of CargoCap is the fully automated operation management. This applies to the control of the tracks, vehicles, shunting and load turnover as well as the various safety controls. The operational control system is integrated into a superior logistic structure, so the customer is able to follow the movement of the goods at any time.
The concept of control and the information processing shows a distributed architecture. It includes specific computers together with sensor technology, actuators and communication interfaces for various tasks.
The interaction of all components requires a safe exchange of information. For that CargoCap possesses a partly cable-based and a partly radio-based communication network.
