Definitions

  • a hydraulic wedge apparatus comprising a wedge-shaped tool constructed as a main wedge arranged between movable jaws, an auxiliary wedge-shaped means operated by a hydraulic drive means and arranged between thrust members capable of interaction with the main wedge and the movable jaws according to the invention
  • the thrust members are mounted on a rod for movement along the axis thereof, one end of said rod being connected to the main wedge on the side of the crest thereof, at the free end of the rod there are means for stopping the second, as viewed from the wedge, thrust member
  • the auxiliary wedge-shaped means is constructed as an auxiliary wedge mounted for interaction by wedge surfaces thereof with the bearing surfaces of the thrust members while the hydraulic drive means is constructed as a hydraulic cylinder, the cylinder sleeve thereof being connected to the auxiliary wedge while the piston rod being connected to one of the thrust members and extending in parallel with the bearing surface of the thrust member.
