Abstract

The rectractable telescopic boom has a lateral 'U' profile when deployed. The top arm (5) cantilevers from a lorry (14). It retracts and folds up into a compact transportable size on the lorry. It is an access way cum working platform for bridge maintenance, and permits access to e.g. a highway bridge soffit from the bridge deck. The lorry supports a prim. longitudinal box beam (2) which contains sec. (3) and third beams (4) of a similar form. Side hung gate beams (5) with wheel mounted (9) movable props (8), pivot about the ends of the lorry substructure to form a track by which the prim. beam (2) moves into an offset parallel position. The sec. beam (3) pivots about a transverse axis to obtain a vertical suspended position. The third beam (4) pivots to adopt a horizontal cantilevered, position parallel to the gate beams (5).
