1. A stabilization manipulator for cooperation in manipulating and moving drilling elements in a drilling rig;
said stabilization manipulator comprising:
a linear guide adapted to be fixed to a drill floor in the drilling rig;
a carriage, comprising a base and sliding blocks, adapted to slide along said linear guide to move at least between a position proximate a well and a position distant from said well;
a first arm, a first end of which is constrained to said base of the carriage, said first arm being rotatable about a horizontal axis;
a second arm, a first end of which is constrained to said base of the carriage, said second arm being rotatable about a horizontal axis;
said second arm is separate from and independent of said first arm;
a first roller constrained to a second end of said first arm, which is adapted to rotate about an axis substantially perpendicular to an extension of said first arm, changing position relative to said first arm; a second roller being constrained to a second end of said second arm, which is adapted to rotate about an axis substantially perpendicular to an extension of said second arm, changing position relative to said second arm; said carriage comprising a rotation system adapted to rotate said base about a vertical axis;
said first arm has a greater longitudinal extension than said second arm;
wherein said first roller associated with said first arm and said second roller associated with the second arm have a substantially same size and shape to act evenly on drilling elements.
