keyed device for the attachment means allowing the lifting of objects, particularly heavy and bulky, in view of their displacement, and objects teams of such a device keyed

摘要

The present invention relates to a locating device for the attachment means allowing the lifting of objects (4), of the type comprising a lug (2), with a hole (6) and welded at the upper part of the body (4) of the object to be lifted, in which engage the means (11) of the lifting of the said object, and means that, characterized in that these latter are formed by a deflector (21) having, viewed from above, in the form of a u whose two wings (8, 9) which extend parallel to the ear, one (8) at least close to the plane (12) perpendicular to the lug passing through the end point of the top of the hole (6), each of the two flanges being separated from the ear of a distance (a) at least equal to the thickness of the means (11), the core (10) of the deflector which connects the wings extending externally to the lug and coming to touch that - ci or being removed by a distance (b) less than the thickness of the means (11), said core (10) being further away from the point (15) of the hole (6) the closest to the body (4) by a distance (c) is greater than the thickness of the means (11). Applicable to the lifting of the handling equipment intended for the sector of the building and public works.
