Patent attributes
The present invention seeks to protect Applicant's HYTORC® LITHIUM SERIES™ Torque Gun Tools for tightening and/or loosening of industrial threaded fasteners. Such tools include: a drive input and output assembly; a turning force multiplication assembly; a dual drive output and reaction assembly; and a yoke-style shifting assembly for any torque mode from lower and/or higher resistance and/or speed. A preferred embodiment includes an electric motor of the drive input and output assembly powered by a battery pack. Advantageously, the yoke-style shifting assembly: improves and simplifies design and operation of shifting; reduces tool size and cost; and increases tool portability, efficiency, reliability and repeatability, all without sacrificing Applicant's many innovations in hand-held, multispeed torque intensifying tools.
