Definitions

  • the present invention relates to a tree support guide according to one of claims 1-4 and an arrangement according to one of claims 5-6 of a tree support guide on a tree support.
  • the invention further relates to a temporary structure according to one of claims 7-9, which comprises a tree support guide or arrangement according to the invention, the use according to claim 10 of the tree support guide and a method according to one of claims 11-12 for forming a temporary structure.
  • poles are used in the construction of steel lattice masts and other structures. Poles of this type are used in particular in challenging terrain, such as forests or mountainous regions, as a replacement for conventional cranes or similar lifting devices. Poles are therefore makeshift devices that usually use an existing part of a structure as a suspension. When in use, the pole is usually connected at its ends to the mast or structure to be erected using tensioning cables.
