Definitions

  • the bucket installed at the construction machine serves to excavate the ground, collect soil and gravel, or load and transport loads such as aggregates.
  • the second set angle may be lower than the first set angle.
  • the third side 403 may be a line convexly curved in a direction opposite to a direction of the curved portion 250 of the back plate 200.
  • the vertical support frame 500 may be provided with a plurality of vertical support frames 500, and the coupling holes 509 respectively defined at the plurality of vertical support frames 500 are mechanically connected to the construction machine, such that the bucket 101 is operated by a driving device of the construction machine.
  • the first set angle means the intersection angle ⁇ 1 between the first planar portion 210 and the second planar portion 220 of the back plate 200 illustrated in FIG. 2 .
  • the second set angle means the intersection angle ⁇ 2 between the first planar portion 210 and the third planar portion 230 of the back plate 200 illustrated in FIG. 2 .
