Abstract: 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.

Abstract: A crane includes a pedestal having a circular periphery, a base supported with respect to the pedestal so as to be rotatable along a substantially vertical axis, a boom fitted to the base so as to be rotatable along a horizontal axis and adjustment elements for adjusting the angle of inclination of the boom. The base is provided with a series of rolling elements which each have a substantially vertical axis, which series of rolling elements can be rolled over the circular periphery of the pedestal and which is always situated on the pedestal facing the boom. As a result, the series of rolling elements is subjected to a tensile load on account of the torque exerted on the pedestal by the boom and is held against the circular periphery of the pedestal. In order to simplify the construction, the base is designed as having a strip-shaped pulling element.

Abstract: A hold crane (6) for elongate elements (4), such as a pipe hold crane for a pipefeeder vessel (1), includes a main frame (7) and support elements (9-12) supporting the main frame above a hold which is carried out for containing the elongate elements. The support elements allow displacement of the main frame in a longitudinal direction of the hold. Hoisting members are provided which are carried by the main frame for lifting an elongate element from the hold vice versa, the hoisting members including at least two hoisting elements spaced apart in the longitudinal direction of the hold. The hoisting elements are suspended from the main frame and are provided coupling elements for coupling onto an elongate element. Stabilizing elements, which cooperate with the hoisting elements, prevent movement of the coupling elements in transverse direction with respect to the main frame while allowing vertical movement of the coupling elements.

Abstract: A crane includes a base (1, 2), an articulated jib (3, 4) which is supported by the base, as well as hoisting elements (5, 9) which are guided from the base via the jib, such as a hoisting cable. The jib includes jib parts (3, 4) which are rotatably supported with respect to each other and with respect to the base (1, 2), as well as respective jib part drives (10-12) for varying the angular position of jib parts with respect to the base or with respect to another jib part. One of the jib part drives has series-connected linear actuators (11, 12), one of which is connected to one of the jib parts and the other of which is connected to a jib part adjoining the jib part and which linear drives cooperate with each other via a guide (13) on the jib.
