Abstract

A mobile working platform suitable for overhead work, with the platform suspended from a jib, has an actuator cylinder (3) mounted on the base of the jib (20) by means of which the jib is raised and lowered, and has an identical cylinder (13) mounted at the other end of the jib to control the swing of the platform (2). The triangles formed by the pivot points of each cylinder arrangement are identical, and the hydraulic chambers of the two cylinders are interconnected by lines so that the larger chamber of one is always connected to the smaller chamber of the other.
