<p>The elevator in form of a scissor has a self propelled chassis (2) to be placed on the ground by linking units (3a, 3b). A set of articulated bars (51) supports a platform in such a way that the elevation of the platform with respect to the chassis is variable and controllable by the bars. The chassis is equipped with dividers (70-77) at its periphery to detect presence of any obstacle in a neighboring zone of the chassis. An independent claim is also included for a process to control elevation movements and lowering movements of a platform of the nacelle elevator.</p> |
