Definitions

  • the invention relates to means for counterbalancing the eanhworking implement carried by a rotary turret of a mechanical excavator or like machine the invention consisting in mounting a counterweight on said turret so as to be rotatable about an axis parallel with and spaced from the turret axis and providing means for locking said counterweight against rotation.
  • counterbalancing means comprising a counterweight mounted so as to be rotatable around an axis parallel to and spaced from the axis about which the turret is rotated and means for locking said counterweight against rotation.
  • F IG. 1 is a side elevational view
  • FIG. 2 is a side elevation of an earthworking machine provided with counterbalancing means according to the invention shown in section;
  • FIG. 3 is a plan view of a counterweight of the counterbalancing means.
  • an excavating or other earthworking machine comprises a chassis I mounted on road wheels and a turret 3 mounted for rotation on the chassis l of the machine by means of a turntable 2 and carrying an earthworking implement 5 mounted on a jib 4 carried on the turret which also carries a fixed counterweight 6.
  • an auxiliary counterbalancing means comprising a counterweight 7 rotatably mounted on a vertical shaft fixed on the turret 3 parallel with the axis x-x about which the turret 3 rotates and radially spaced from said axis x-x.
  • the counterweight is substantially sickle or C-shaped and is rotatably mounted on the shaft 10 at one of its ends so as to be rotatable from the position shown in full lines to the position shown in broken lines in FIG. 3.
  • Means are provided for locking said counterweight 7 against rotation about shaft 10, said means comprising locking pins 8 carried on a suitable fixed part of the turretand insertable in suitably positioned holes 9 in the counterweight 7.
  • the counterweight 7 sickle or C-shaped and rotatable about axis 10 it can be rotated about said axis into an operative position, that is the position shown in full lines in FIG. 3, and locked in that position by a locking pin 8 so that it counterbalances the weight of the earthworking implement 5 to the supporting jib 4 during operation of the earthworking machine.
  • the counterweight can be rotated about axis 10 into an inoperative position shown in broken lines in FIG. 3 and locked in that position by locking pin 8.
  • the counterweight in its inoperative position substantially surrounds the axis of the turntable 2 of the turret and thus is positioned symmetrically relative to the turret and the road wheels whereby the weight distribution is more suitable for transportation of the machine, i.e. is more evenly distributed between the front and rear wheels of the machine.
  • the locking pins 8 carried by the turret and the holes in the counterweight are so located as to enable the counterweight to be locked in two different positions, that is an operative and an inoperative position shown in full and broken lines respectively in FIG. 3, the
  • counterweight may be provided with a series of spaced inreceiving holes whereby the counterweight can be locke in other positions relative to the axis of the turret turntable 2 where working conditions require such positioning of the counterweight.
  • a mechanical earthworking machine comprising a wheeled chassis, a turret rotatably mounted on said chassis and earthworking implement carried by said turret and means for counterbalancing said implement said counterbalancing means comprising a weight mounted for rotation about an axis parallel to and spaced from the axis about which said turret rotates and means forlocking said weight against rotation relative to said turret or said chassis.
  • a mechanical earthworking machine wherein said counterweight is'rotatably mounted on a shaft fixed on said turret 3.
  • said locking means comprises locking pins carried by a fixed part of said turret and holes in said counterweight for receiving said pins to lock said counterweight against rotation relative to said turret.
  • a mechanical earthworking machine wherein said counterweight is rotatably mounted on a shaft fixed to said turret and said locking means comprise locking pins carried by a fixed part of said turret and holes in said counterweight for receiving said pins to lock said counterweight relative to said turret.
