A platform for research: civil engineering, architecture and urbanism
A platform ladder apparatus (2) has a transport position and a use position. The apparatus (2) has a ladder (4) and a working platform (20). A proximal side of the platform is pivotally connected at an upper end of the ladder, thus being pivotable towards the ladder (4) to a stowed position. The apparatus further comprising a foldable safety railing (40) which protects a user. The safety railing (40) comprising a pair of proximal posts (42), a pair of distal posts (44), and guard rails (46, 47, 49) extending between the posts (42, 44). The safety railing (40) being foldable into a stowed position in the transport position.Each proximal post (42) has an upper part above the platform (20), and a lower part under the platform (20). The lower part is connected below the platform for pivotal movement about the platform pivot axis (A1). A load transferring rail member (47) extends between the upper parts of the proximal posts (42).
