Abstract (en)
[origin: US4718563A] The instant invention concerns a transportable overhead gantry for spanning a roadway having two supports linked in an articulated manner to a cross-member. The cross-member is adjustable for height, for example using a winch operable to move the cross-member along the supports and, being made up of three or four parts, can be telescopically retracted. The supports can be folded towards each other in a plane defined by the cross-member so that the entire overhead gantry can be transported on a conventional truck. The overhead gantry can be erected at any point along a multi-lane expressway without special machinery or equipment and is thus suitable for the rapid and temporary display of traffic signs.
