Definitions

  • This invention has for object a universal hooking system for the lifting of concrete products.
  • the sidewalls have the form of tilted shoulders and do not contribute to supporting the hooking ring to maintain it upright.
  • the lateral tooth solution is better than the central tooth one, but presents the drawback that the lateral tooth can be easily burred, that is deformed on the outer side, not having other support than that of the concrete edge that fixes it immediately under the surface.
  • the aim of the present invention is to obviate the above-mentioned drawbacks.
  • the ring must remain necessarily upright at least on the side of the stop on the respective shoulder, while it may be rotated in the opposite direction.
  • said latch may be rotated passing through the hole of the anchor bolt (22), thereby hooking it.
  • sheath (120) has a toroidal upper semi-ring narrower on the upper side (1201) that for 180° can allow the free rotation of the second ring (11) that will be able to be hooked by a crane over the concrete surface of the product.
  • the anchor bolt illustrated in Fig. 3 is shown with the tooth, but it is obvious that according to the present invention, the fundamental characteristic is the presence of shoulder shaped orthogonal stop endings (20), and the tooth (21) can be also totally absent.
