An aircraft boarding apparatus has a passenger bridge that has a confinement structure coupled to the second passenger bridge. The confinement structure exerts a ground-anchoring effect on the second passenger bridge to offset the ultralight configuration of the passenger bridge.

Repurpose decommissioned elevated highways, decommissioned elevated railways, decommissioned bridges, viaducts, and causeways and or new construction of elevated spans by making provision for providing energy from non-fossil fuel sources, such as solar, wind, geothermal and/or hydrothermal, to provide the energy needs of habitable structures and facilities built upon such decommissioned elevated bridges, elevated railways or bridges. Such is done to provide energy independence for such spans that are to be free of fossil-fuel motor vehicle traffic (or trains).

A dock leveler includes a frame. A deck plate is rotationally coupled to the frame at a deck hinge. A lip plate defines a lip plate lower surface and an edge. A lip hinge is coupled to the lip plate and a connection plate to provide relative pivotal movement of the lip plate and the deck plate. The connection plate is positioned below the deck plate. A support link extends from the lip plate to the connection plate. The support link is rotationally operable with respect to the lip plate and slidably operable with respect to the connection plate.

An apparatus comprising a gangway having a proximal end and a distal end. A cage assembly is connected to the distal end of the gangway. The apparatus further comprises a container spotting system including a camera mounted such that its field of view will show a hatch cover of a container when the hatch cover is in a predetermined location. Video electronics are in electrical communication with the camera. The container spotting system further includes a display device in electrical communication with the video electronics, the display device being operative to show at least a selected portion of the field of view of the camera. The camera may comprise an outdoor dome camera mounted to an underside of the gangway.

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.

Apparatus (100) and method for providing active motion compensation control of an articulated gangway (200) which comprises at least one fixed part fixedly mounted on a sea going vessel, a movable part being movable relative to the fixed part, and at least one actuator for moving the movable part relative to the fixed part. A first position reference device provides position and attitude information (m) of the vessel referenced to earth. A second position reference device provides position and attitude information (y) of the movable part referenced to the gangway. An actuator driver generates an actuator control output in response to a regulator signal (R). An active motion compensation controller device receives the position and attitude information m and y, an operator control input (J), and the velocity information (y{dot over (y)}) of the movable part. A differential kinematic (DiffKin) device compute and outputs a current position (p) and velocity (v) of the gangway endpoint from m and y. An active motion compensation (AMC) device computes and outputs a reference position (pp) and velocity (vv) of the gangway endpoint from J, p and v computed by the DiffKin, An inverse kinematic (Inv) device computes and outputs a position reference () and velocity reference (i) of the gangway endpoint from p and vv computed by the AMC. A regulator (Regulator) device computes and outputs said regulating signal (R) in response to inputs of said a position reference () and velocity reference ({dot over ()}) computed by the AMC.
