Gin Pole Device for Raising and Lowering a Tower

Abstract

The present invention provides a gin pole device for raising and lowering a tower that allows tension and length adjustments of the guy wires during tower erection to keep the tower as straight as possible, so that weight loads are equally distributed on the guy wires, thereby avoiding tower deformation.

1 . A gin pole device for raising and lowering a tower, comprising:
 a pole having an anchoring end for anchoring the pole;   at least two winching mechanisms mounted on the pole, comprising respectively at least two guy wires having their free ends connectable to different sections of the tower, the winching mechanisms allowing independent tension and length adjustments for each of the guy wires; and   guiding means mounted on a portion of the pole, distal to the winching mechanisms, for guiding the guy wires between the winching mechanisms and the sections of the tower.   
   
   
       2 . The gin pole device according to  claim 1 , wherein said winching mechanisms are mounted proximate the anchoring end of the pole. 
   
   
       3 . The gin pole device according to  claim 1 , wherein said winching mechanisms are mounted in a superposed relationship along the pole. 
   
   
       4 . The gin, pole device according to  claim 1 , wherein the guiding means are provided with a guardrail for preventing the guy wires from leaving the guiding means. 
   
   
       5 . The gin pole device according to  claim 1 , wherein said guiding means are mounted at a free end of the pole opposed the anchoring end thereof. 
   
   
       6 . The gin pole device according to  claim 5 , wherein the guiding means comprise at least two rounded tracks mounted at the free end of the pole for respectively receiving the guy wires therein. 
   
   
       7 . The gin pole device according to  claim 6 , wherein said rounded tracks are respectively provided with a non-abrasive guiding surface. 
   
   
       8 . The gin pole device according to  claim 6 , wherein the guiding means are provided with a guardrail mounted above the tracks for preventing the guy wires from leaving the tracks. 
   
   
       9 . The gin pole device according to  claim 5 , wherein the guiding means comprise at least two pulleys mounted at the free end of the pole for respectively guiding the guy wires therein. 
   
   
       10 . The gin pole device according to  claim 1 , further comprising a connecting device mounted at the anchoring end of the pole for connecting the pole to a lower end of the tower. 
   
   
       11 . The gin pole device according to  claim 1 , wherein each of the winching mechanisms is provided with a worm gear for preventing an unwanted unwinding of the guy wire connected thereto.
