Abstract
A tool for tensioning safety cable to a predetermined tension limit includes a reciprocally rotatable wheel mounted for rotation about a point on the tool for incrementally advancing the cable. A gear assembly is coupled to the rotatable wheel and has at least one driven gear connected to affect rotation of the wheel. A power actuator is coupled to the gear assembly and adapted for affecting reciprocal rotation of the at least one driven gear to thereby affect rotation of the wheel. The cable is attached to the wheel after being drawn through bolts to be restrained by the cable. The tool includes apparatus for terminating the cable to restrain it with the desired tension.

A tool for tensioning safety cable to a predetermined tension limit comprising:
- rotatable means mounted for rotation about a point on the tool for incrementally advancing the cable;
- a gear assembly coupled to said rotatable means and having at least one driven gear connected to affect rotation of said rotatable means;
- a power actuator coupled to said gear assembly and adapted for affecting rotation of said at least one driven gear;
- tension control means operatively associated with said power actuator for inhibiting rotation of said rotatable means when tension on the cable reaches a preselected value;
- means coupled to said power actuator for automatically terminating the cable comprising:
- a toggle assembly;
- a cable terminating member coupled to be driven by said toggle assembly;
- and
- means for actuation of said toggle assembly for terminating the cable at the preselected tension limit;
- and
- said power actuator comprising a linear actuator coupled in driving relationship with said gear assembly, said linear actuator including a first drive rod connected to be reciprocally driven by said power actuator and a second drive rod frictionally engaged with said first drive rod, said second drive rod being coupled to said gear assembly and said first drive rod being coupled to actuate said toggle assembly, said second drive rod being coupled to frictionally slide on said first drive rod when tension on the cable reaches the preselected tension limit.
A tool for tensioning a cable to a preselected tension value comprising:
- a handle assembly having a generally cylindrical configuration;
- a linear actuator mounted in said handle assembly and having a first and a second power actuated, reciprocating rod extending therefrom;
- a cable tensioning assembly mounted to said handle assembly, said cable tensioning assembly including cable tensioning means coupled to said first rod and cable terminating means coupled to said second rod;
- and
- means frictionally coupling said first rod to said second rod whereby tensioning motion of said first rod is terminated upon tension in the cable reaching said preselected value.
