Description

TECHNICAL FIELD

The present invention relates to a system for the transportation of loads and/or persons at height.

BACKGROUND ART

Several systems are known to be used for the transportation of loads and/or persons at height along routes that are generally difficult to cover using conventional motorised means of transport or on foot.
Generally, these types of system make use of cable transport means, such as cableways, where one or more cars are attached along a cable that runs suspended along a predefined route, e.g. along the slope of a mountain.
Specifically, this type of system carries cars of known type along a closed route between two arrival/departure stations, where the system's users can get in and out of the car.
This way, the systems of known type allow for easy transportation of loads and/or persons along routes that are difficult to cover between the arrival/departure stations.
This type of system is however susceptible to improvements related to their functionality and convenience of use.
In fact, the cars used by the known type of systems are bound to the cable of the corresponding means of transport, from which they are released only to perform maintenance and/or replacement operations of the car itself and/or of the system.
Therefore, the cars are substantially unusable when released from the system's cable. In addition, after being released, the cars are difficult to move, as they are particularly bulky.
In addition, the arrival/departure stations of the systems are not always easily reachable by the users, for example because of the morphological characteristics of the area where the system is installed and/or the weather conditions.
These drawbacks limit the functionality of the systems of known type, making them inconvenient and complicated to use.

DESCRIPTION OF THE INVENTION

The main aim of the present invention is to devise a system and a related car which allow increasing the functionality and the way of use of the same compared to the systems and cars of known type.
Another object of the present invention is to devise a system and a related car which allow overcoming the above mentioned drawbacks of the prior art within a simple, rational, easy, effective to use and low cost solution.
The objects set out above are achieved by the present system having the characteristics of claim 1.
The objects set out above are achieved by the present car having the characteristics of claim 12.
