Patent ID: 11111114

Abstract:
Expandable heavy equipment 1, comprising a first frame element 5, a connector 11, at least one elongated pull element 14, and further frame elements 7. The pull element 14 is connected to the first frame element 5 with a first coupler 31 and to one 9 of the further frame elements 7 with a second coupler 35. The pull element 14 is in a folded state in a transport condition and in an extended state in a working condition. The pull element 14 comprises load bearing fibers/fibres 141 extending from the first coupler 31 to the second coupler 35. The pull element 14 comprises at least one flexible part 43 and at least two stiff parts 45. The flexible part 43 has a lower bending stiffness than the two stiff parts 45 and enables the pull element 14 to be arranged in the folded state.
