Abstract

Joint combined system for insertion of electrical circuits apt to control the movements of a crane and the like, whose control is done at a distance and in particular with respect to mechanical organs for said movements, characterized to include two combiner elements arranged in two superimposed planes and mounted on a frame in a common frame, with their axes orthogonal to each other, with the drum of each combiner on the one hand a maneuvering pinion and on the other hand an exhaust system for each of the working and stopping positions, being controlled the sprockets of said combiners, each by means of a chain that takes the movement of a handle or actuating handle in two perpendicular directions respectively on two sleeves orthogonal to each other and integral each of the shaft bearing the driving wheel of a chain, whose combined double movement handle comprises two distinct and parallel levers, arranged under the action of a spring that tends to move them away, so that the approach of said levers, caused by the pressure of the hand of the operator, determines the closure of a first electric circuit that makes possible, successively, the closure of the circuits that they are controlled by the angular displacement of the handle with respect to the plane perpendicular to the axis of the combiner drums.
