Apparatus for lifting and/or moving operations of drilling equipment

Abstract

An apparatus for lifting and/or moving operations of drilling equipment on a deck, the apparatus includes a load-bearing device, a synchronizing device, a synchronizing linkage comprising at least one guide which receives the synchronizing device, and a suspension device comprising at least one lifting arm. The at least one lifting arm comprises a first torque arm and a second torque arm. The first torque arm comprises a first end connected to the suspension device, and a second end connected to the synchronizing linkage so as to provide a first synchronizing link. The second torque arm comprises a first end connected to the synchronizing linkage so as to provide a second synchronizing link, and a second end connected to the load-bearing device. The first torque arm and the second torque arm are respectively further connected via the first synchronizing link and the second synchronizing link to the synchronizing device.

What is claimed is:  
     
         1 - 10 . (canceled) 
     
     
         11 . An apparatus for lifting and/or moving operations of drilling equipment on a deck, the apparatus comprising:
 a load-bearing device;   at least one common synchronizing device;   a synchronizing linkage comprising at least one guide which is configured to receive the least one common synchronizing device; and   a suspension device comprising at least one lifting arm, the at least one lifting arm comprising at least one pair of torque arms comprising a first torque arm and a second torque arm,
 the first torque arm comprising a first end and a second end, the first end being connected to the suspension device, and the second end being connected to the synchronizing linkage so as to provide a first synchronizing link, 
 the second torque arm comprising a first end and a second end, the first end being connected to the synchronizing linkage so as to provide a second synchronizing link, and the second end being connected to the load-bearing device, and 
 the first torque arm and the second torque arm being respectively further connected via the first synchronizing link and the second synchronizing link to the at least one common synchronizing device. 
   
     
     
         12 . The apparatus as recited in  claim 11 , wherein the at least one lifting arm further comprises:
 a first synchronizing arm comprising a first end and a second end, the first end being connected to the suspension device, and the second end being connected to the synchronizing linkage, and   a second synchronizing arm comprising a first end and a second end, the first end being connected to the synchronizing linkage, and the second end being connected to the load-bearing device,   wherein,   the first torque arm is arranged parallel to the first synchronizing arm, and   the second torque arm is arranged parallel to the second synchronizing arm.   
     
     
         13 . The apparatus as recited in  claim 11 , wherein the at least one guide is arranged perpendicular to a direction of travel of the at least one lifting arm. 
     
     
         14 . The apparatus as recited in  claim 11 , wherein in that the at least one common synchronizing device comprises at least one wheel, at least one slide block or at least one roller bearing. 
     
     
         15 . The apparatus as recited in  claim 11 , wherein the at least one common synchronizing device comprises a shaft to which each of the first synchronizing link and the second synchronizing link are connected. 
     
     
         16 . The apparatus as recited in  claim 11 , wherein the first synchronizing link and the second synchronizing link each comprise at least one beam. 
     
     
         17 . The apparatus as recited in  claim 11 , wherein the at least one lifting arm further comprises a motive device configured to move the at least one lifting arm. 
     
     
         18 . The apparatus as recited in  claim 17 , wherein the motive device comprises a first end and a second end, the first end being connected to the suspension device, and the second end being connected to the first torque arm or to the second torque arm. 
     
     
         19 . The apparatus as recited in  claim 17 , wherein the motive device comprises a first end and a second end, the first end being connected to the suspension device, and the second end being connected to the first synchronizing arm or to the second synchronizing arm.
