A displaceable working apparatus provided with a platform having an extensible boom and being displaced on a guide rail is disclosed. The apparatus has a main frame secured to a main support which is movably secured to the guide rail and a main stabilizing mechanism for immovably securing the main frame to the adjacent roof surface. An extensible boom having a working free end which is equipped with a working element and is pivotally secured to a rotating support base positioned under the main frame. The boom is rotatable on the rotating support base and is angularly positionable with respect to the rotating support base. A drive is mounted on the frame to displace the platform along the guide rail.

Displaceable working apparatus with extensible boom

A displaceable working platform comprising a main frame having stabilizing extension posts secured thereto for immovably securing the main frame to surrounding surfaces. A displaceable platform is slidingly secured to the main frame. The platform is displaceable on the main frame from a storage position to a working position. An extensible boom is secured on a rotating support base which is secured to the displaceable platform. The boom has a working free end at which a working element is secured. The rotating support base is rotatable by a motor and a boom is extensible by an hydraulic system which is also provided to regulate the angular position of the boom by controlling hydraulic pistons connected between the boom telescopic sections, and the rotating support base.
