Safety system for a clamping tool

Abstract

The present invention relates to a safety system for a gripping device comprising: a clamping tool having a body, at least one bore through the body of the clamping tool, at least one elongated connecting element extending through the bore, and withholding means arranged to couple the connecting element to the clamping tool body at two different positions of the bore separated from each other. The invention also relates to a corresponding safety arrangement for a gripping device.

         13 . A safety system for a gripping device comprising:
 a clamping tool having a body;   at least one bore through the body of the clamping tool;   at least one elongated connecting element extending through the bore; and   withholding element arranged to couple the connecting element to the clamping tool body at two different positions of the bore separated from each other.   
     
     
         14 . The safety system according to  claim 13 , wherein the body of the clamping tool is a casted item with a single solid body preferably made of metal. 
     
     
         15 . The safety system according to  claim 14 , wherein said bore is a through bore comprising two outer first portions and a middle second portion located in between said two outer first portions, where said outer first portions have a diameter which is larger than the diameter of the middle second portion, and further wherein the withholding element has a body which comprises at least one cross-section which is larger than the diameter of the middle second portion of the bore, where one withholding element is positioned at each of the outer first portions of the through bore in such a way that they are prevented from entering the middle second portion of the bore. 
     
     
         16 . The safety system according to  claim 15 , wherein each of said withholding element is dimensioned so that when it is positioned inside the outer first portion a passage is created between the outer first portion of the bore and the atmosphere outside the bore. 
     
     
         17 . The safety system according to  claim 16 , wherein said withholding element is in the form of a securing component arranged to be coupled to end portions of the connecting element. 
     
     
         18 . The safety system according to  claim 13 , further comprising at least one shock absorbing component arranged at an outer portion of the bore and adjacent to said withholding element. 
     
     
         19 . The safety system according to  claim 18 , wherein said shock absorbing component is made of a deformable/pliable material. 
     
     
         20 . The safety system according to  13 , wherein said elongated connecting element is a bar element made of steel material. 
     
     
         21 . The safety system according to claim  1 , wherein said elongated connecting element is a wire element. 
     
     
         22 . The safety system according to claim  1 , wherein the safety system is configured for a gripper for gripping a pipe. 
     
     
         23 . An energy absorbing arrangement comprising:
 an elongated connecting element having at least two end portions;   each end portion is coupled to a withholding element; and   a shock absorbing component arranged adjacent to the withholding element at each end portion of the elongated connecting element.   
     
     
         24 . A safety arrangement for a gripping device comprising:
 a clamping tool having a body;   at least one elongated connecting element coupled to the body by a withholding element at two different positions separated from each other.
