Manually portable structural apparatus comprising a rigid structural element (101) configured to be releasably coupled to at least one other like rigid structural element (301). A bearer element (201) having a substantially planar upper face (202) extends between first and second elongate side beams (204, 205), which each have a first connector arrangement (208) at a first end (209) thereof and a second connector arrangement (210) at the second end (211) thereof; the first and second connector arrangements (208, 210) providing a two-part releasable, mechanical, coupling arrangement. The first and second elongate side beams (204, 205) are configured to provide first and second side walls (216, 601) extending upwardly from the upper face (202) of the bearer element (201). Use of a rigid structural element (101) as part of a short gap crossing and as part of a stretcher. A rigid structural element (101) in which the bearer element (201) defines foot receiving apertures (219, 220) therethrough and use thereof as part of a ladder. A rigid structural element (101) comprising carbon fibre. |
