Definitions

  • the present invention relates to a crane shovel for building reinforced concrete cutoff walls and similar.
  • reinforced concrete cutoff walls and similar are often used in the construction of certain types of underground structures, such as garages, stores, cellars, tanks, etc.
  • reinforced concrete cutoff walls requires a special type of crane shovel capable of digging trenches of constant width and depth, depending on the type of cutoff wall being built.
  • known crane shovels for building reinforced concrete cutoff walls comprise : a self-propelled track-mounted undercarriage I for moving over any type of ground; a movable superstructure II mounted on self-propelled undercarriage I and revolving about a vertical axis; a boom III projecting substantially vertically from movable superstructure II; and a special grab bucket IV, for reinforced concrete cutoff walls, fixed to the top end of boom III by one or more supporting cables V looped about a number of transmission pulleys VI at the top end of boom III.
  • Supporting cables V are wound and unwound by a number of winches on movable superstructure II, so as to move grab bucket IV, on command, along the vertical line through the top end of boom III.
  • a crane shovel for building reinforced concrete cutoff walls and similar, comprising a self-propelled undercarriage; a movable superstructure mounted for rotation on the self-propelled undercarriage; a boom projecting from said movable superstructure; and a grab bucket, for reinforced concrete cutoff walls, suspended from said boom by means of at least one supporting cable; the crane shovel being characterized in that said boom projects from said movable superstructure in a substantially horizontal direction.
  • Number 1 in Figures 2 and 3 indicates as a whole a crane shovel specially designed for building reinforced concrete cutoff walls and similar in highly confined spaces.
  • Crane shovel 1 comprises: a self-propelled undercarriage 2, specially designed for moving over rough ground, and preferably, though not necessarily, mounted on tracks; a movable superstructure 3 mounted in known manner on self-propelled undercarriage 2 to revolve about a vertical axis of rotation A; a boom 4 projecting from movable superstructure 3 in a substantially horizontal direction; and a grab bucket 5, for reinforced concrete cutoff walls, suspended from the free end 4a of boom 4 by means of one or more supporting cables 6.
  • boom 4 is hinged at the other end to a supporting bracket 7 projecting from the top of the body of movable superstructure 3, and is maintained in a substantially horizontal position by a hydraulic piston 8 having a first end hinged to boom 4, and a second end hinged to the body of movable superstructure 3.
  • boom 4 is hinged to supporting bracket 7 so as to rotate about a horizontal axis of rotation B; while hydraulic piston 8, projecting from movable superstructure 3, supports boom 4 centrally and is adjustable in axial length to adjust, on command, the tilt angle ⁇ of boom 4 with respect to its horizontal operating position.
  • boom 4 has one or more transmission pulleys 9, about which cable/s 6 supporting grab bucket 5 for reinforced concrete cutoff walls is/are wound.
  • boom 4 is a telescopic type, i.e. is defined by a number of sections (two in the example shown) connected to each other telescopically by one or more hydraulic actuators (not shown) for adjusting the overall axial length of boom 4 in known manner.
  • movable superstructure 3 also comprises an orienting device (not shown) for rotating movable superstructure 3, with respect to self-propelled undercarriage 2, about axis of rotation A; and at least one winch 10 for winding and unwinding, on command, cable/s 6 supporting grab bucket 5 for reinforced concrete cutoff walls, so as to move grab bucket 5 along the vertical line V through the free end 4a of boom 4, and also open and close the bucket.
  • winch/es 10 is/are fixed to and project from supporting bracket 7 at the point at which boom 4 is hinged to supporting bracket 7.
  • crane shovel 1 is equipped with a known grab bucket 5 for reinforced concrete cutoff walls, which requires two independent supporting cables 6 for moving grab bucket 5 along vertical line V and for opening and closing the bucket.
  • Movable superstructure 3 is therefore equipped with at least two independent winches 10, each for winding and unwinding a respective supporting cable 6 on command.
  • crane shovel 1 preferably, though not necessarily, also comprises two lateral running boards 11 located on opposite sides of movable superstructure 3, and each of which is capable of supporting the weight of at least one person, is fixed to the body of movable superstructure 3, and can be removed easily and quickly, when necessary, to reduce the overall width of movable superstructure 3.
  • each lateral running board 11 is defined by a preferably, though not necessarily, parallelepiped-shaped box, which may be used to advantage as a tool box.
  • each lateral running board 11 is defined by a parallelepiped-shaped box 12 fixed in easily removable manner by a long side wall to the body of movable superstructure 3; and by a top cover plate 13 hinged by a long lateral edge 13a to the lateral wall of box 12.
  • Top plate 13 defines the lid of box 12, and is movable between a closed position ( Figure 3) closing the top opening of box 12, and an open position ( Figure 4) exposing the top opening of and permitting access to the inside of box 12.
  • top plate 13 defines the tread surface of lateral running board 11.
  • crane shovel 1 for reinforced concrete cutoff walls as described and illustrated herein greatly reduces the overall height of the machine, thus enabling it to operate in confined spaces and, in particular, inside existing buildings.
  • the drastic reduction in the overall height of the machine also eliminates the need for extensive ground supporting elements, so that smaller self-propelled undercarriages 2 and movable superstructure 3 can be used, thus reducing the production cost of the machine.
  • self-propelled undercarriage 2 may be equipped with removable track skids to reduce the overall size of the undercarriage during transport.
