1. A hand-held, battery-powered in-line crimp tool comprising:
a frame having a working head portion and a handle portion, the working head portion having a C-shaped structure, and the handle portion including a drive system that translates rotational movement of an electric motor to linear movement of a ram extending at least partially onto the working head portion, the drive system including:
the electric motor adapted to be powered by a battery;
a gear reduction assembly used to reduce the output speed of a shaft of the electric motor by a predetermined factor;
a ram drive system having a drive arm operatively coupled to the gear reduction assembly, and a drive surface operatively coupled to the drive arm such that rotation of the drive arm causes linear movement of the drive surface; and
a linkage assembly operatively associated with the drive surface, such that when the shaft of the electric motor rotates in one direction the drive surface causes the linkage assembly to move from a retracted position to an extended position and when the shaft of the electric motor rotates in an opposite direction of the one direction the drive surface causes the linkage assembly to move from the extended position to the retracted position.
