A jalousi wall assembly for a passenger bridge, which jalousi wall assembly including a first jalousi wall in turn having a first end and a second end, which first end is arranged to be wound up on, and off from, a first roll with a first vertical rotation axis (A2), and which second end is arranged to be fastened to the passenger bridge, wherein the first roll is arranged to be fastened to the frame of a movable opening of the passenger bridge and to follow horizontal movements of the frame by the first jalousi wall being wound up on, or off from, the first roll, whereby a horizontal length of the first jalousi wall, between the first end and the second end, is adjusted in response to a horizontal movement of the frame. The application relates to a jalousi wall assembly further including a wire having a first and a second end, which first end is wound about the first vertical rotation axis (A2) such that the first jalousi wall is wound up on the first roll when the wire is pulled at its second end, and in that the jalousi wall assembly further includes a wire tension device including a gas spring arranged to maintain a tension in the wire while the frame moves.

A portable, height-adjustable gangway includes a lower tower structure comprising a lower landing and a lower movement assembly comprising a first set of wheels permitting the lower tower structure to travel over ground, an upper tower structure comprising an upper landing, an upper movement assembly comprising a second set of wheels permitting the upper tower structure to travel over ground, and an extending tower support connecting the upper movement assembly and the upper landing and comprising expandable struts configured to move the upper landing towards and away from the upper movement assembly, and a travellator pivotally connected to the lower tower structure and pivotally connected to the upper tower structure such that, when the expandable struts of the tower support extend at least one of towards and away from the upper movement assembly, the escalator tilts. The escalator can be a continuous set of stairs, a gondola-like trolley, or both.

The invention discloses a multi-bar linkage mechanism based conveyor, comprising a gantry system, a multi-bar linkage mechanism based conveyor boom, a boom support, a two-drum winch, a roller unit and an automatic control system. The gantry system, the two-drum winch and the boom support are mounted on a deck of a hull. The conveyor boom is formed of multi-bar linkage mechanisms, the movement of which can be changed. Rollers are mounted on the conveyor boom. The rear segment of the conveyor boom is articulated with the boom support. The two-drum winch is connected to the multi-bar linkage mechanism based conveyor boom via a steel wire rope and by a set of gantry pulleys. A hydraulic device and a control device are arranged between adjacent multi-bar linkage mechanisms. A tension sensor is arranged at an end of the steel wire rope. The whole conveyor is controlled by the automatic control system.

The present invention discloses a method for operating a multi-bar linkage mechanism based conveyor. Stretching the mechanism based conveyor comprises: an automatic control system is started to control a first two-drum winch, a second two-drum winch, and hydraulic cylinders in a multi-bar linkage mechanism based conveyor boom to operate together until the mechanism enters an operating state, and the first two-drum winch, the second two-drum winch, and the hydraulic cylinders in the multi-bar linkage mechanism based conveyor boom stop operating. Then, the angle of the multi-bar linkage mechanism based conveyor boom can be adjusted by controlling the operation of the second two-drum winch. Retracting the mechanism based conveyor comprises: the automatic control system is started to control the first two-drum winch, the second two-drum winch, and the hydraulic cylinders in the multi-bar linkage mechanism based conveyor boom to operate together until the mechanism enters a non-operating state.

Disclosed is a boarding bridge having a transparent display. The boarding bridge includes a first tunnel connected to a terminal gate, a second tunnel connected to be capable of overlapping with the first tunnel, and a control unit. The first tunnel and the second tunnel each have a plurality of transparent displays, and include at least one overlap detecting sensor unit. Through the overlap detecting sensor unit which detects whether a transparent display of the first tunnel and a transparent display of the second tunnel overlap, the controller can selectively control the playback of images on the transparent displays of the first and second tunnels.

Present teachings relate to a gangway comprising a distal end on which an end effector unit is attached. The end effector unit has an outer surface at least a certain portion of which is adapted to be in contact with an installation, wherein a movement of a rotatable element in the end effector unit corresponds to a movement of the distal end with respect to a reference point on the installation when the end effector unit is in contact with the installation, the movement of the distal end being at least along one of the axes related to the installation. The present teachings also relate to a method for repositioning a gangway to a desired position on an installation or a target structure. The present teachings also relate to: a vessel or a watercraft comprising the gangway; and an installation comprising the gangway. The present teachings further relate to a computer software product implementing any of the method steps herein disclosed.
