A displaceable working scaffold with a vertically adjustable working platform and with legs arranged in pairs and each consisting of two parts movable relative to each other. One of the problems with known working scaffolds of this type is the mounting and dismounting procedures, which are difficult and time-consuming, and to a large extent this is due to the fact that the known scaffolds consist of a relatively great number of parts that must be joined and dismounted each time the known scaffolds are to be set up and taken down, respectively. I.a. to solve this it is suggested according to the present invention that a jack (16) is arranged between the upper and lower parts of the legs (10) in each pair of legs by means of which the working platform (3) is raised and lowered and that detachable staying means (23, 24) for staying the pair of legs are arranged between the working platform (3) and the upper portions (10a) of the legs, a hinge (11, 12) being provided for their connection to the working platform, around which the relative leg (10) can be turned towards the working platform (3) after at last partly loosening said connection. |
