Abstract
An installation including on the one hand trolleys equipped each with a hydraulic jack and roller members and on the other hand parallel supporting-beams which support the boat which is arranged so that its longitudinal axis is perpendicular to these beams which bear upon the jacks of two trolleys running on two parallel tracks, the jacks forming three groups of jacks connected hydraulically so that the resultants of these groups are located at the corners of a triangle, and it is characterized by the fact that it includes at least three parallel tracks upon which the trolleys run which support the supporting-beams which are arranged so as to form at least two lines of beams which are displaced perpendicularly to the longitudinal axis of the boat.
