A movable and dynamic work after construction linking two points separated by a natural or man-made obstacle, allows the permanent crossing of this obstacle. The work includes a deformable apron (1) which extends between said two points. The work comprises a set of elongated elements (2, 3). An assembly of several pairs of elements (2, 3) is disposed along the apron (1). The work comprises drive means (8) disposed at one end or at both ends of said work for adjusting the apron (1) lengthwise. The drive means (8) are arranged so that, when the means (8) are actuated, they drive the assembly of the pairs of elements (2, 3), so as to bulge the central portion of the apron (1) when the means (8) are actuated.

The present invention relates to a telescopic access bridge (2), a unit provided therewith, and method there for. The bridge comprises: a base unit (4); an elevating unit (8) having a first end with a first hinged connection to the base unit and a second end; a bridge (28) comprising a main bridge part (30) and a telescopic bridge part (32), the bridge having one end with a second hinged connection to the second end of the elevating unit.

A walkway installation comprising a base (1) intended to be fastened to a support construction, such as to the deck (5) of a ship (6), as well as a base bridge part (2) that is connected at one end so it can be rotated around an upright base axis of rotation (11) with the base. Furthermore, a main bridge part (4) is provided on the other end of the base bridge part (1) as well as a hinge construction between the base bridge part (1) and the main bridge part (2). The hinge construction has an upright main axis of rotation (12) and an auxiliary axis of rotation (13) aligned transversely to the upright main axis of rotation and transversely to the main bridge part. By rotating the gangplank parts, the installation may be adjusted in a reliable and quick way in relation to a fixed object or another vessel.

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.

A movable passenger bridge to embark and disembark passenger to/from a ship is provided. The passenger bridge is movable and includes one or several telescopic sections, where the passenger bridge is arranged to connect to an opening in the hull of the ship. The section of the passenger bridge that is arranged closest to the ship has the largest cross section area. The passenger bridge is arranged so that the passengers can walk through the sections of the passenger bridge to a connection section, in the shape of a cabin, arranged to be connected to the mentioned opening in the hull of the ship or to an opening in the rail at deck of the ship. The passenger bridge is supported by a stand which is movable on the port quay, and that the passenger bridge is height-adjustable by means of the stand.
