Abstract: The suspension and hoisting system for a load support comprises two cable circuits, each comprising a cable (C1, C2) fixed at one of the ends thereof to a fixed point (Pf1, Pf2) and at the other end to a lifting apparatus (T1, T2) and being reeved around deflection pulleys (A1, A2, A3, B1, B2, B3) mounted on two parallel shafts (Ax) located adjacent one and the other end, respectively, of the load support, the lifting apparatus (T1) of one of the two cable circuits being provided above one of the ends of the load support and the lifting apparatus (T2) of the other cable circuit being provided above the other end of the load support.

Abstract: The invention relates to a device for guiding a moving body (1) along a tensioned cable (4) attached at intervals to a building facade (3) and at a given distance therefrom. It comprises a pivoting device (7) formed by a pair of stars (8) parallel, coaxial and integral with one another, the points (9) of which face one another, pivoting about an axis perpendicular to the cable axis (4), the axis of the pair of stars (8) being rotationally integral with the structure of the guided moving body (1).

Abstract: The tractive apparatus has two clamping grippers each comprising a pair of jaws actuated by clamping links connected to an operating lever through connecting links pivotably mounted on this lever on each side of a pivot pin of the lever situated in the extension of a guide bar on which one of the two jaws of each gripper slides, the two grippers moving in opposite directions while being clamped in one of the two directions of movement. The guide jaw of each gripper is formed by a hollow body which serves as housing and bearing point for one of the ends of a pre-clamping spring whose other end exerts its action on a clamping link actuating the other jaw of the same gripper.

Abstract: An apparatus for clamping and longitudinally moving an elongate tension or traction means such as a wire rope relative to a casing of a lifting apparatus is provided with two pairs clamping jaws operated by clamping levers. Pairs of clamping jaws are alternately closed against the rope to move the rope in the direction of traction. In order to avoid subjecting the rope to compressive loads in the longitudinal direction during clamping, the clamping jaws are interconnected so that they are immovable in relation to one another in the longitudinal direction of the wire rope. Clamping keys for generating the clamping pressure are irrotationally connected to the clamping levers and pivotally mounted in circular apertures of one of the clamping jaws. These clamping keys slidably press onto the other clamping jaw directly or indirectly such that they cannot apply a compressive force in the longitudinal direction of the wire rope to the clamping jaw.
