The segment (2a) has a washing element (3) to treat walls of frame work, and retractable arm (9) and lower and upper main arms (12, 13) mounted on length of the segment in series and articulated with each other to allow the segment to be retracted or deployed. A proximal end is equipped with an assembly unit to assemble the end on a vehicle, where the end is moved along length of the frame work, and a distal end carries the tool. The main arms form a pantograph (1b) whose folding and unfolding movements are controlled by a double-acting cylinder (14) to cause a translation of the tool. An independent claim is also included for a vehicle for treating walls of a framework. |
