Definitions

  • This invention consists in providing a mechanig g cal excavator or other earth working machine having a rotary [52] U.S.Cl 214/138, implement carrying turret with stabilizing legs mounted on a 7 37/103, 212/145 support which is rotatably mounted on the machine about an [51] Int.
  • MECHANICAL EXCAVATOR OR OTHER EARTH WORKING MACHINE stabilize the machine while earth-working operations are being carried out.
  • the stabilizing legs, or other stabilizing means are positioned on the machine so as to provide optimum effect while the earth working machine is in use but this sometimes presents problems when the machine has to be driven from one side to another along public highways, especially when such stabilizing means are positioned at the sides of the machine.
  • the object of the present invention is to provide an earthworking machine with stabilizing means which are so positioned and arranged as to provide optimum stabilizing effect when the machine is in use without however constituting a source of danger or contravening traffic regulations when the machine is being driven along a public highway.
  • the earth-working machine comprises an endless track or wheeled chassis a turret rotatably mounted on said chassis and carrying an earth-working implement and stabilizing means mounted on said chassis wherein said stabilizing means comprises a rotary support rotatably mounted on said chassis about an axis coaxial with the turret axis, stabilizing legs mounted on said support and each provided at its outer free end with an anchoring shoe having a length not greater than the overall width of the machine.
  • FIG. 1 is a diagrammatic side elevation of an earth-working machine, in the form of a mechanical excavator, according to the invention
  • FIG. 2 is a perspective view illustrating the arrangement for mounting the stabilizing means on the machine chassis
  • FIG. 3 is a plan view of FIG. 2,
  • FIG. 4 is a part sectional side elevation of a means on the machine chassis
  • FIG. 5 is a modified arrangement for mounting the rotary turret and the stabilizing means on the machine chassis and for locking the turret and stabilizing means in position.
  • the rotary turret carries means, indicated generally at 4, for carrying out earth-working operation, said means comprising a jib 5 articulated at 6 to said turret and having pivoted to its outer free end at 9 a lever 8 to which is pivotally mounted an earthworking implement in the form of a scoop 11. Operation of the jib 5, lever 8 and scoop 11 is effected in known manner by hydraulic rams 7, and 12 respectively.
  • the earth-working machine is provided with stabilizing means for stabilizing said machine while carrying out earth-working operations, said stabilizing means comprising a rotary support 13 to which two stabilizing legs l4, 15 are pivotally mounted at 16 and 17 respectively on diametrically opposite sides of said support 13.
  • Each of said stabilizing legs 14, I5 is provided at its outer free end with an anchoring shoe 21 and 22 respectively and said stabilizing legs are pivotable by rams l8 and 19 respectively into an operative position, in which the anchoring shoes are in contact with the ground, or in an inoperative position, in which said anchoring shoes are out of contact with the ground.
  • the rotary support 13 is rotatably mounted on the chassis I, between said chassis and the rotary turret 3, about a vertical axis coaxial with the turret axis.
  • the rotary support 13 can be locked in one of at least two positions by locking means 20 which comprises a locking pin which passes through a perforated lug or projection on said rotary support 13 and engages in a hole in a fixed part of the chassis l as indicated in FIG. 4 and 5.
  • the locking means 20 are so arranged that said I rotary support 13 can be locked in one position in which the stabilizing legs project fore and aft of the machine substantially parallel to the longitudinal axis of the machine i.e., in the inoperative positions of said stabilizing legs (FIG 1), or in a second positions in which the stabilizing legs project outwards from the lateral sides of the vertical at right angles to the longitudinal axis of the vertical i.e., in the operative positions of the stabilizing legs (FIG. 2).
  • the mounting of the rotary turret 3 and the rotary support 13 on the chassis I of the machine may be carried out in any suitable manner, for example as illustrated diagrammatically in FIG. 4 or FIG. 5.
  • the rotary support 13 is mounted on a ring of roller bearings 24 carried on the chassis l and said support 13 carries on its upper part a second ring of roller bearings 23 upon which the turret 3 is rotatably mounted.
  • a crown wheel 25 Around the periphery of the ring of the roller bearings 23 is a crown wheel 25 with which meshes a pinion 27 fixed on the driving shaft of a motor 26 carried by the turret and by which said turret is rotated.
  • the rotary turret 3 and the rotary support 13 are rotatably mounted on rings of rollers bearings 28and 29respectively in a similar manner to that of FIG. 4 except that in this embodiment the ring of roller bearings 28 on which the turret is rotatable is not carried by the rotary support 13, as in FIG. 4, but on n extension (not shown) of the chassis which passes up through the rotary support 13.
  • the ring of roller bearings 28 on which the turret is rotatable is not carried by the rotary support 13, as in FIG. 4, but on n extension (not shown) of the chassis which passes up through the rotary support 13.
  • the turret 3 is rotated by a motor 26 through a pinion 27 and crown wheel 25 but in this embodiment locking means 30, similar to the locking means 20 above described, are provided for locking the turret 3 and the rotary support 13 together so that said turret and rotary support can be rotated simultaneously by the motor 26.
  • the locking means 20,30 are released.
  • the rotary support is rotated to position the stabilizing legs 14,15 so that they project laterally from each side of the machine and the rams 17,18 are operated to move the anchoring shoes 21 and 22 into contact with the ground as shown in FIG. 2.
  • the anchoring shoes are of such a size as to engage the ground over as great an area as possible to enhance stabilization, but their length must not be greater than the overall width of the machine so as to ensure that they do not project beyond the sides of the machine when it is being driven along a public highway.
  • the locking means 20 is first released so that the support 13 can rotate relative to the chassis l.
  • the earth-working implement is lowered to the ground so as to immobilize the turret 3 relative to the support 13.
  • the motor 26 is then operated so that the support 13 is rotated through pinion 27 and crown wheel to bring the stabilizing legs into operative position.
  • the locking means 20 is then again locked and the stabilizing legs are lowered to bring their anchoring shoes into contact with the ground whereupon the earth-working implement is raised so that the turret 3 can be rotated relative to the chassis by means of the motor 26.
  • the earth-working machine may be provided with a wheeled chassis instead of an endless track chassis as shown.
  • An earth-working machine such as a mechanical excavator, comprising an endless track or wheeled chassis, a turret rotatably mounted on said chassis and carrying an earth-working implement and stabilizing means mounted on said chassis, said stabilizing means comprising a rotary support rotatably mounted on said chassis about an axis coaxial with the turret axis, stabilizing legs mounted on said support and each provided at its outer free end with an anchoring shoe having a length not greater than the overall width of the machine.
  • An earth-working machine according to claim 2 wherein means are provided for locking said rotary support and said turret in their operative or inoperative position.
