Nacelle has the following sorting - directional for any intervention on the framework, in particular metallic

摘要

Of horizontal movement in two perpendicular directions x and y of a boat for cleaning and or paint with a framework, in particular metallic, comprising the tie beams horizontal, such as 11 to 15, parallel and at a distance n of one another, the nacelle being composed essentially of a flat - form 2 suspended by four cables 31, 32, 33, 34, the movements of relaxation and put under tension are controlled by four motors fixed to the flat - form. The displacement of the nacelle on a distance n is done in two operations by means of two rigid rods 41, 42 of the length proper which, by rotation about their anchoring point on the framework, guide the nacelle in the course of a first lateral descending movement followed by a second lateral ascending movement.
