Abstract:
A movable apparatus, for mooring or anchoring self-gripping supports in a telecommunication line, in which the mooring or anchor device of self-gripping two-way devices which carry cables, is made integral with a movable structure, which may freely slide a along a sustaining post, said structure comprising an anchor chain (25), allowing lowering of the line to ground level and successive lifting of the line to the operative position at the end of maintenance; said lowering of the line being obtained by exploiting the gravity force acting on the line itself, and the subsequent lifting to the operative position of said mooring or anchor device, being obtained by a traction of said anchor chain exerted by the operator, said apparatus being, characterised in that it is positioned on a post and in that said chain supports an anchor element (21) having an inverted â€œUâ€  configuration, on which there are welded two spacers (22â€², 22â€³) with a flattened elliptical shape, which are hooked by four self-gripping supports; the said chain adapted slides through an upper, shaft bearing ring (27â€²), and through a lower, shaft bearing ring (27â€²), in order to allow the lowering or the lifting of the line, and the said chain being fixed to a first hook and a second hook, wherein said chain is to be locked in a first position to the first hook (28) at about 4.00 meters of height, and in a further, more elevated position, at about 5.00 m, to the second hook, in which said chain is fixed.
