Definitions

  • Sheet metal clamps for sheet metal transport in accordance with DIN 1502, Par.1.5 are generally known and can be seen in the attached brochure, see also Occupational Safety Report by Helmut Zurstrassen, Mannheim, address of the author: conhandels- und Lagerei-Berufsartenschaft in Mannheim, in the magazine BG 760 , December 1984 edition, further report by Dipl.-Ing. R. Süchting, Hamburg, in the magazine “Tiefbau” from Erich-Schmidt-Verlag, Kunststoff, December 1989.
  • the clamps are mainly used for the erection of lying sheets - vertical transport and horizontal storage.
  • the clamps are manufactured for a load capacity of 200 kg and gripping range 1 - 15 mm, but also for a load capacity of 30 to and gripping range up to 500 mm.
  • the vertical force is redirected into a horizontal force by a lever mechanism. This holding force decreases when touching down or bumping.
  • the invention is based, to reduce the risk of accidents when gripping and transporting sheets. According to the article of the civil engineering professional association, such a clamp is not yet known.
  • the advantages are clear to see.
  • the invention can be used for a large number of the previously known types of clamps. It can be used for all load capacities and for various applications.
  • the main advantage is occupational safety, as is urgently required by all professional associations.
