Abstract:
The passenger boarding bridge includes a first tunnel including a first fixed passage on which a passenger walks; and a second tunnel including a second fixed passage on which the passenger walks, the first tunnel being inserted into the second tunnel from one end side of the second tunnel, the second tunnel having another end side connected to a cab, the second fixed passage being fixed to the another end side. The second tunnel includes a movable passage including multiple plate floor members in a chain manner, the movable passage having one end fixed to the second fixed passage of the second tunnel in a pivotable manner. Accordingly, a passenger boarding bridge in which a passage level difference is eliminated at a joint part between an inner tunnel and an outer tunnel can be realized.
Abstract:
A gangway construction 1 for providing access between a vessel 3 and an offshore object 33 comprises a support frame 2 and a movably guided gangway 10. A guiding assembly comprises an upper and lower rotatable pulley wheel 5, 6. A first cable 8 is connected to the frame or the gangway at a forward and backward connecting position 16, 17 and extends in a longitudinal direction between this forward and backward connecting position. With this the first cable 8 extends from its forward connecting position 16 towards the lower pulley wheel 6, is guided in for example a counter clockwise direction along at least part of the circumference of the lower pulley wheel 6 and in for example a clockwise direction over at least part of the circumference of the upper pulley wheel 5, and from the upper pulley wheel 5 extends towards its backward connecting position 17.
Abstract:
A method and apparatus for opening a mechanical bridge, the apparatus including at least two adjacent bridge spans where the first of the bridge spans is removable from its initial position and the second of the bridge spans is at least partially movable into the space originally occupied by the first span so that at least a portion of the second bridge span can be separated from yet a third adjacent span thereby forming an opening between the second and third spans and another method whereby a span is first moved laterally and then longitudinally to open a section of the bridge.
Abstract:
There is disclosed a bridge extendable away from, and retractable back towards, a quay, and including winch means, at least one flexible connection for extending the bridge and at least one flexible connection for retracting the bridge, said flexible connections coupling the winch means to the bridge, one of said flexible connections being wound and the other unwound by the winch means upon operation thereof to extend or retract the bridge, and weights suspended from said flexible connections between the winch means and the bridge. When a boat is secured to the outboard end of the extended bridge, movement of the weights allows the bridge to follow movement of the boat.
