The stabilized platform 3 is suspended from upper support means 4. Support means 4 include traction means such as an electric motor rotating main wheel 42, with auxiliary wheel 43, for pulling or releasing part of the cable 41, thus moving the platform 3 up or down, in the direction 22 (z axis).
Furthermore, support means 4 may move laterally, in the direction 21 (x axis) for example along lateral movement tracks 44 mounted there. The vertical and lateral movements can bring the suspended platform 3 to a desired location on the wall of the building 1.
Additionally, the platform 3 includes means for self-propulsion using one or more propellers or ventilators 31, three such units being mounted in the embodiment as illustrated.
The ventilators may exert a force and/or cause a movement in directions 23, 24, 25 as illustrated.
Furthermore, each ventilator may be mounted on a base with means for changing its direction, for example in elevation and/or azimuth, as detailed elsewhere in the present disclosure.
Thus, the direction of the force applied by each ventilator can be controlled and adjusted as desired.
For example, ventilators may be activated to bring the platform 3 closer to the building or even inside it to a limited extent. This may be desirable when applying a brush to forcibly clean the wall.
In another application, winds may move the platform away from the desired location. The ventilators may apply a counter-thrust to keep the platform in place.
In yet another application, the platform may start a pendulous movement, for example after a lateral movement of unit 4. The ventilators may be so activated as to dampen, or stop, such undesired movements or oscillations.
Usually, unit 4 will be used for large movements, while the ventilators in platform 3 will be used for fine lateral movements and stabilization.
A platform cable 41 includes mechanical support cable, as well as conduits for electric power, communications, water, pneumatic pressure and/or detergents.
Platform 3 may be equipped with means for holding various accessories to perform a desired task, for example a device for cleaning windows and building facades using brushes or sand blasting.
The goal: performing various tasks at high locations, such as the side of a building, without endangering workers, using a platform which is movable in space.

313, for the elevation angle adjustment. The ventilator frame 313 can also be rotated in azimuth using a second stepper motor 314, which is mounted on frame 313 and with its axis connected to the support rod 315.
Fig. 5 details a platform 3 with means for stabilizing it located in a box 6 under the platform. This is another preferred embodiment of the device of Fig. 2, for example.
The stabilized platform 3 is suspended from a cable 41 which may include a mechanical support cable, electric power, control signals, pneumatic pressure, water, etc. Movement of the device
The device includes a plurality of propellers 31 and 32 as illustrated, and preferably also a propeller on the lateral wall of the box 6 opposite that with the propeller 31. These propellers may be used to move the platform 3 in a generally horizontal plane, under operator's control.
Usually these are small movements and/or forces applied to counter wind forces.
The cable 41 may be used to move the device vertically and for large horizontal movements. This allows the device a tri-dimensional movement in space.
The propellers 31, 32, etc. preferably are mounted on axes to allow their rotation about horizontal and vertical axes as illustrated, so as to direct the thrust (the force activated to stabilize the platform 3) in the desired direction. A two axis positioner may be used for each propeller.
