Definitions

  • the earth-moving machines currently used for excavation work and the like are provided with jaws opening and closing around a single axis or, in the best of cases, on two axes with fixed point. Their use and performance is therefore limited to the movements which the above devices allow.
  • the device which is the subject of the present patent application not only makes better and faster work possible, but also offers new possibilities for using the earth-moving machine; as set out in the claims, hence its character of novelty and originality.
  • the device comprises: levers 2 welded to the tubes 10, each being integral with a jaw; main connecting rods 3 connect the axes 8 welded to the fittings 11, to the axes 9 fixed on the levers 2; the double-acting cylinders 4 actuating the levers 2, as well as the main connecting rods 3; the axis of rotation of the jaws is moved laterally, which gives the machine a great grip force; connecting rods 6 connecting the main connecting rods 3 to a frame 5 by which the machine is maintained and guided; levers 7 stabilize the chassis 5 in the center of the device in any angle of opening of the jaws.
  • the machine suitable for the use of the machine described can transmit its force to one or the other of the jaws; this force exerted on the frame 5 in the working direction of the jaws, generates a simultaneous reaction of the two jaws. This therefore results in a new possibility of application.
