There is disclosed a ladder platform apparatus (2), comprising a ladder (4), a working platform (20), and a foldable safety railing (40). Locking devices (100; 200) are arranged to lock railing posts (44) of the safety railing (40) in their raised position of use. Each locking device (100; 200) has a locking member (102; 202) movable between a non-locking position in which an associated railing post (44) is free to rotate in relation to the working platform (20), and a locking position in which the locking member (102; 202) is in engagement with a front side and a rear side, respectively, of the railing post (44), and in which the locking member (102; 202) is prevented from rotating in relation to the working platform (20), thereby preventing the railing post (44) from rotating away from its locked raised position.

A platform ladder apparatus (2) has a transport position and a use position in which the apparatus is arranged to lean against a wall (W) for performing work at an elevated level. 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 such that it may be pivoted towards the ladder (4) to a stowed position essentially parallel to the ladder (4). The apparatus further comprises a pair of wall support arms (80) for stabilizing the apparatus in the use position in relation to the wall. The wall support arms (80) are connected to the platform (20) for movement between a stowed arm position in which the arms (80) project out from a distal side (24) of the platform (20) thereby preventing use of the apparatus, and a stabilizing arm position in which the arms (80) project sideways from the platform (20) in opposite lateral directions, respectively, for stabilizing the apparatus (2) in relation to the wall (W).
