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.

An access module for a modular access structure has a longitudinally and vertically extending first frame and a longitudinally and vertically extending second frame. The second frame laterally opposes the first frame. A deformable lower support structure laterally extends between the first and second frames. The lower support structure includes a deck spanning a longitudinal length of the access module. A deformable upper support structure laterally extends between the first and second frames. The upper support structure is spaced above the deck. The access module is configurable by deformation of the lower and upper support structures between an extended configuration in which the first and second frames are spaced apart a first distance and the deck is generally horizontal and a collapsed configuration in which a distance between the first and second frames is less than the first distance. The access module is adapted to be fastened end to end to a second access module.

A modular system for constructing an elevated pathway includes a first pathway segment comprising a first elevated platform portion; first edge supports to bare a load of the first elevated platform portion, wherein the first edge supports contact a ground surface and create a grade separation between the ground surface and a bottom side of the first elevated platform portion; and a first joint. The modular system also includes a second pathway segment comprising: a second elevated platform portion; second edge supports to bare a load of the second elevated platform portion, wherein the second edge supports contact the ground surface and create a grade separation between the ground surface and a bottom side of the second elevated platform portion; and a second joint to attach to the first joint to limit a motion of the second pathway segment relative to the first pathway segment.

An aircraft boarding apparatus has a passenger bridge that has a confinement structure coupled to a 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.

A deployable truss with modified primary orthogonal joints. The construction of these joints causes the center-hinged primary chords on opposite sides of a truss bay to fold inward in a plane orthogonal to the folding planes of the side diagonals while the two secondary chords fold in planes orthogonal to the plane of the in-folding primary chords. This provides for stiffness and stability during deploy and retract. The unique joint configuration permits the truss to deploy one bay at a time in a stable manner while having lateral bending stiffness, and the truss thus can extend and retract in a sequential manner. It can deploy integral flat panels nested between the secondary folding chords, or use cross bracing in lieu of panels. The truss can be triangular, square or rectangular in cross-section. A powered support frame may be used in conjunction with the truss.

The pneumatic support according to the invention has pneumatic bodies 61 to 63 which can be placed under pressure and which operationally keep a compression member 51 and a tension member 52 at a distance apart, resulting in a pneumatic support with high loadability but also, disadvantageously, with high operating deformation. The connection elements 57, 58 extending in a zigzag shape between the compression member 51 and the tension member 52 over the length of the support 50 are preferably diagonal struts formed as flexible tension members and reinforce the support 50 with respect to the pneumatic supports of the prior art in such a way that the deformation of said support in the case of an asymmetrical load, as is the case with a bridge over which vehicles travel, is for example still 10%.

A transportable foldable bridge that has a folded transport state and an unfolded installation state. The bridge includes a first ramp element, a second ramp element and an intermediate element with two opposing ends. A first end of the intermediate element is connected to the first ramp element and the other end of the intermediate element is connected to the second ramp element. An articulating connection is provided between the first ramp element and the intermediate element. In the transport state, the first ramp element and the intermediate element are folded and the second ramp element constitutes an extension of the intermediate element.

A crossing device aids in crossing from a near side to a far side of an obstacle. It comprises a lead assembly that is projected to the far side of the obstacle and that includes an anchor assembly and a pulley. The anchor assembly has a base, a launch tube that is secured to the base, a spike that is housed within the launch tube, and a propellant charge. The anchor assembly is anchored on the far side of the obstacle by remotely initiating the propellant charge. The explosion force drives the spike through the launch tube and the base, into a landing surface. A bridge is connected to the pulley and is pulled to span across the obstacle. The bridge, lead assembly, and anchor may be collected on the far side for additional uses.
