A fall prevention system for guarding a side of a platform, the system having first 5 and second members (5 of fig.2), a rope / cable 12 and a tensioner 6 for tensioning the rope/wire, the system having a deployed state wherein the rope / wire extends between the two members and guards the side of the platform, and a stowed state wherein the elongate member is positioned (preferably lowered) to allow access to the platform side. Ideally the fall prevention system comprises (at least) two posts 5 slotted in brackets 4 on the flat bed of a trailer truck, with the wire extending to and fro between them. The posts preferably have pulleys 16 located in brackets 17 (see fig.6) around which the wire rests loops. The wire is preferably tensioned by a winch 6. An independent claim relates to a retractable ladder 11 adaptable to changes in height as the trailer platform is loaded or unloaded. |
