Definitions

  • This minimum stability value S min is usually determined by standards.
  • the standard ISO 10567 applies to hydraulic excavators in the construction and transhipment sector.
  • FIG. 2 corresponds to that according to FIG. 1.
  • the corresponding contact forces F1, F2, F3 are present and F4 drawn on the wheels. These are to be considered when the excavator 10 is not supported by the four-point support.
