Patent ID: 7950309

Claim:
A torque intensifying tool for tightening and loosening threaded connectors, comprising drive means; at least one torque intensifier means receiving a torque from said drive means and having gear means and a torque intensifier housing portion; a driving element turning one part of a threaded connector; a reaction element reacting against a neighboring object during the turning of the one part of the threaded connector by said driving element; and means switching the torque intensifying tool between two modes of operation and configured so that in one mode of operation said driving element turning one part of the threaded connector operates with a high speed and a low torque and said torque intensifier housing portion is connected with said driving element turning one part of the threaded connector and said reaction element reacting against the neighboring object and said torque intensifier housing portion together with said driving element turning one part of the threaded connector and said reaction element reacting against the neighboring object turn in one direction, and in another mode of operation said driving element turning one part of the threaded connector operates with a low speed and a high torque and said torque intensifier housing portion together with said reaction element reacting against the neighboring object is disconnected from said driving element turning one part of the threaded connector so that in the other mode of operation said torque intensifier housing portion together with said reaction element reacting against the neighboring object receives a turning force in an opposite direction while said driving element turning one part of the threaded connector receives an equal turning force in the one direction, and so that said driving element turning one part of the threaded connector turns in said one mode and in said another mode while said reaction element reacting against the neighboring object turns in said one mode and reacts in said another mode.
