Definitions

  • the boom supporting body and the boom either swing together as a unit about a fixed vertical body axis, or the boom assembly swings about a fixed vertical axis at one end of the body while the body remains stationary. In either case it is impossible to position the excavator so that the bucket at the outer end of the boom can excavate a trench immediately adjacent to and alongside a building wall with the boom moving up and down in a plane parallel to the building wall.
  • An additional object is to provide a mechanical shovel which includes, in addition to the above mentioned construction features, a horizontal tilt axis between the body and its supporting mobile chassis, which makes it possible to level the body when its transporting chassis is located on a hillside, which in turn makes it possible to dig a trench vertically into the ground alongside a building wall, even though the ground slopes upward or downward away from the building wall.
  • FIG. 1 is a perspective view of a self-propelled excavator embodying the invention
  • FIG. 2 is an exploded view, in perspective, showing details of construction of the excavator illustrated in FIG. 1;
  • FIGS. 3 and 4 are top plan schematic views illustrating typical operations of which an excavator embodying the invention is capable.
  • FIG. 5 is a front elevational view schematically illustrating the excavator performing another type of operation.
  • an excavator embodying the invention includes a power driven mobile ground supported chassis which includes a weight supporting frame; an intermediate frame mounted on the chassis for lateral tilting movement with respect thereto about a central fore and aft horizontal axis; a body mounted on the intermediate frame for swinging movement about an axis normal to the plane of the intermediate frame; a work performing assembly including an elongated bucket carrying boom mounted on one end of the body for swinging movement about an axis parallel to the body swinging axis, and also for movement about a transverse axis normal to the body swinging axis; a power unit carried by the body; means 3,167,194 Patented Jan.
  • the chassis of the excavator illustrated is designated as a whole by the numeral 11
  • the body supporting intermediate frame is designated as a whole by the numeral 16
  • the body is designated as a whole by the numeral 15
  • the boom assembly is designated as a whole by the numeral 18.
  • the mobile chassis includes conventional endless tracks 12 which are driven independently through a transmission 14, which in turn is driven by a hydraulic motor 13 mounted on the transmission housing.
  • the chassis frame includes fore and aft spaced parallel transverse frame members 20 and 21 which rigidly carry fore and aft aligned pivot pin bearings 22.
  • the intermediate frame 16 includestransversely spaced parallel frame members 25 and transversely disposed parallel channel cross section frame members 26 and 27, rigidly connected to the frame members 25.
  • the transversely disposed frame members 26 and 27 are fitted with central fore and aft aligned bearings 29 which cooperate with the bearings 22 on the chassis frame, and with separate pivot pins, to mount the intermediate frame on the chassis frame for tilting movement about the axis 22.
  • the intermediate frame carries a body pivot pin 35 which is rigidly mounted in upright position on the cross frame member 27.
  • the intermediate frame 16 includes a transverse arcuate channel section track 39 which is welded or otherwise rigidly secured to the forward ends of the frame members 25, and three rollers 36 rotatably mounted on spaced brackets 37, one on frame member 26, and the other two at the respective aft ends of the frame members 25.
  • the purpose of the track 39 and the rollers 36 will be explained in connection with the body section 15.
  • the elongated body 15 is generally oval shaped in plan form, as clearly shown in FIGS. 3 and 4. It includes spaced parallel side frame members 48, a rigid transverse cross frame member at its forward end connected to the forward ends of the frame members 48, but not shown in FIG. 2. It also includes rear channel section cross frame members 49 and 51, which are likewise rigidly secured to the aft ends of the frame members 48.
  • the body frame rigidly supports a heavy transverse plate 50 which has a central hole 52 for receiving the pin 35 on the intermediate frame.
  • the body frame rigidly carries three arcuate track members 53, 54 and 55 which in eifect constitute a three-quarter circular turn table guide for thebody, since all three of these members lie in the same transverse plane. They are of channel section to receive the rollers 36 on the intermediate frame 16.
  • the body rigidly carries a bracket 57, which in turn carries transversely spaced rollers 58 which are received in and roll on one flange of the channel in track member 39 when the body is mounted in its normal position on the pivot pin 35.
  • the rollers 58 in the arcuate channel member 39, and the central roller 36 which rolls in the channel of track member 53 serve to stabilize the body on the intermediate frame 16 and prevent its fore and aft tilting with respect to the intermediate frame.
  • the two rollers 36 at the opposite sides'of the intermediate frame, seated in the track members 54 and 55 on thenbody serve to stabilize the lateral tilting movement of the body with respect to the intermediate frame.
