Definitions

  • FIG. 1 a construction equipment machine 10 of the so-called backhoe- loader type.
  • Such machine comprises a chassis 12 mounted on four wheels and a cabin 14 mounted on the chassis for receiving an operator of the machine.
  • a bonnet 16 receives the machine' s main engine.
  • Such a machine therefore exhibits the main looks of an agricultural tractor. It derives its name from the fact that it carries two main pieces of equipment, namely a loader equipment 18 at the front, and a backhoe equipment 20 at the rear.
  • the loader equipment 18 comprises essentially two loader arms 22 which are articulated on the chassis around a horizontal axis A l near the rear end of the bonnet 16 and which extend longitudinally towards the front on both sides of the bonnet 16.
  • a loader bucket 24 having a generally forward facing cavity is articulated around a horizontal axis A2.
  • the proximal part 34 of the dipper assembly 32 is for example a fabricated steel sheet structure which extends along the lengthwise axis X-X of the dipper assembly and which exhibits approximately the shape of a U when viewed in cross section, the U shape enclosing partially an inner space 38 which is open towards its top, at least along a substantial portion of the proximal part 34.
  • the distal part 36 is at least partially received within the inner space 38 of the proximal part 34, both lengthwise and in cross section. In any case, at least in an extended configuration, the free end 40 of the distal part 36 extends lengthwise beyond the free end 42 of the proximal part 34, outside of inner space 38.
  • a backhoe loader such as the one described above is well known to the skilled man in the art and is for example commercially available as “Volvo BL 71 ".
  • the distal part 36 of the dipper assembly comprises a rectilinear profile 48 made by extrusion of metal, said profile having a closed cross- section around at least one inner cavity 50.
  • the rectilinear profile 48 is best shown on Figures 4 and 5 where it is represented just after its fabrication by the extrusion process.
  • the rectilinear profile extends along the lengthwise axis X-X of the dipper assembly, and it is therefore possible to define the axis X-X as being the extrusion axis.
  • the rectilinear profile 48 is devoid of welding around its cross-section. This avoids any deformation which may be caused by a welding operation.
