The Jobridge is a portable bridge that is used to cross over grade beams or other obstacles on a construction site. It is constructed of 6061 aluminum to allow it to be lifted and moved with light machinery or equipment. It is coated with a non-slip coating that is safety yellow. The Jobridge is rated for a maximum weight load of 12,000 lbs. To cross the Jobridge the equipment must be 12,000 lbs or less and the tracks must be 8 ft wide or less. Obstacles that are traversed must be less than 30 inches wide and less than 13 inches tall in the center. The Jobridge is more suited for crossing buried, or partially buried, obstacles or narrow trenches like grade beams. The intent is to prevent damage to the grade beam side wall (obstacle) or steel reinforcements that may protrude from the grade beam.

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.

A ramp system which may include first and second components. The first component may include horizontal and vertical portions, and a hook. The horizontal portion may be supported by a lip of a structure, and may have a width equivalent to a length of the lip. The vertical portion may be coupled with, and hang downward from, the horizontal portion, and may have the same width as the horizontal portion. The hook may be coupled with the vertical portion, and may have the same width as the horizontal portion. The second component may include a protrusion and channel. The protrusion may have a width equal or less than the width of the horizontal portion, and be supported by the hook. The channel may be coupled with the protrusion, and have the same width. The channel may receive a planar component which forms a sloped surface of a ramp.

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.
