Mason's adjustable chimney-platform arrangement

An articulable, shape-changeable, elevatable platform assembly comprising a generally “H” shaped structure being attachable distal end of an articulable support arm of a transport vehicle, the platform assembly being arranged to adjustably surround an elevated structure on at least three sides thereof, the platform assembly comprising:

• an elongated bridging member attachable at a midpoint thereof to the articulable support arm of a transport vehicle, the elongated bridging member having a 1st end and a 2nd end, wherein an elongated 1st side platform is controllably and slidably attached to the 1st end of the elongated bridging member;
• and wherein an elongated 2nd side platform is independently controllably and independently slidably attached to the 2nd end of the elongated bridging member so as to adjustably adapt to size variations of an adjacent and/or parallel sides of a surrounded elevated structure by the platform assembly;
• and wherein at least one of the elongated side platforms is curved in its elongated direction;
• and wherein at least one elongated side platform is connected to the elongated bridging member by a supportive rotary unit to permit the at least one side platform to be swivelably moved angularly into close non-orthogonal proximity towards and away from a vertical structure.
