A stopping system for a cab of boarding bridges for accessing aircraft and ships, which boarding bridge comprise a round structure (1) to which the cab (2) is attached with rotational capabilities, having stopping means made up of a cab rotation blocking mechanism, formed by a linearly movable lance (12), and of a coupling part (11) for said lance, that is integral to and rotates with the cab (2). The movement of the lance is controlled by a sensor that detects the operations of the cab drive mechanism. |

1. A stopping system for a cab of boarding bridges for accessing aircraft and ships, which boarding bridges comprise a round structure to which the cab is attached with rotational capabilities, having stopping means to halt the rotation of the cab, and with a operating sensor of the drive mechanism of the cab, wherein the braking means are activated by the operating sensor, when the latter detects the breakdown or failure of the drive system of the cab,
the braking means comprising a cab rotation blocking mechanism, formed by a linearly movable lance, which is attached to the frame that supports the round structure, and of a coupling part for said lance, that is integral to and rotates with the cab; the lance is aligned with the coupling part and to it are associated retention means, which are capable of keeping said lance in an inactive position, separated from the coupling part, and pushing means, in charge of propelling said lance toward an active position, in which said lance fits into the coupling part, blocking it; the retention means can be released by means of the operating sensor when said sensor detects a failure or breakdown of the cab drive system, so as to allow the lance to move up to its active position actuated by the pushing means. |
