A platform for research: civil engineering, architecture and urbanism
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.
