Definitions

  • the drive unit comprises at least one pressure cylinder, the ends of which are coupled by means of two at least more or less U-shaped coupling members to two respective pairs of transmission arms, each connected to a jaw.
  • the active ends of the pressure cylinder transmit the force generated thereby onto the transmission arms at an axial distance relative to the pivot centre line. The tensile and pressure forces occurring can be absorbed easily using simple mechanical constructions.
  • the pincer grab 1 will be further apparent without explanation.
  • the jaws 6, 7 can pivot around the shafts 4, 5 between the closed position shown particularly clearly in fig. 1 in which they together form a grab and a desired open position.
