Definitions

  • Raising clips for carriers are well known, e.g. in our brochure, see article by Dipl.-Ing. R. Süchting, Hamburg, in the magazine “Tiefbau”, Issue Dec. 89, from the Erich-Schmidt-Verlag, Kunststoff. Opening a clamp from below with a rope is already known, but without a stepping mechanism. There are shackles that are opened with a stepping mechanism. However, this requires that the erected parts receive a corresponding hole.
  • the vertical holding force is converted into a horizontal clamping force.
  • the load hanging in the crane hook causes the load (carrier) to be held in place, as is also the case with normal scissors tongs.
  • the holding force is reduced when touching or bumping.
  • the invention has for its object to make the release of the clamp safe from a distance when erecting beams, and also operations such as lowering loads in water or pits or the holding of silo containers can be designed safely.
  • the achievement of the object is ensured according to the invention.
  • the clamp can only be released from the load in two steps. Unintentional loosening by rear hooks or incorrect operation is not possible, at the same time visual control of the step switch.
  • Figure 3 shows the individual workflows.
  • flag 8 is at the bottom
  • lever 6 is at the top (Fig. 1).
  • locking pin 5 automatically engages in drive plate 12.
  • Spring 7 now (after loosening the rope) brings lever 6 and flag 8 into a horizontal position (Fig. 3).
  • the clamp is now opened, removed from the load and is ready for a new use.
  • the advantage of the invention is significant for occupational safety when erecting beams and long components. It can be used successfully in various clamp and plier designs. The trade association regards the invention as a significant improvement in occupational safety.
