  • the main arm side distance 133-122 is greater than the frame arrangement side distance 133-112 (see also figure 2a) .
  • the lowered position of the lifting arrangement 133 thereby refers to a state, where the equipment connector portion 133-22 of the main arm 133-2 is located in a lowermost position in the vertical direction Z, i.e. nearest position to the road surface.
