Access equipment for overhanging or convexly curved walls

摘要

The present invention relates to an access equipment for overhanging or convexly curved walls with– a superstructure (18) which, at the upper edge of the wall (k) can be mounted movable,– a working platform (11), which at the upper carriage (18) is suspended and,– an extension arm (19) with two extension arms (21), which on the working platform (11) at a distance from each other and to be pivotable about a common shaft and are held in each case a ballast - weight (20), via support cables (25) on the revolving superstructure (18) and fixed by means of the support cables (25) associated actuating means (24) with respect to the working platform (11) are pivotable. The ballast - weights (20) are provided on the extension arms (21) to be movably guided in the longitudinal direction and there are drive means are provided, in order to enable the ballast - weights (20) along the auslagerarme (21) to the method.
