ABSTRACT:
An apparatus for crimping a terminal onto a wire includes a hydraulic cylinder including a hydraulic ram, two normally open crimper jaws closeable by the hydraulic ram, and a hydraulic pressure supply for delivering hydraulic pressure to the hydraulic cylinder to operate the hydraulic ram and close the crimper jaws. The hydraulic pressure may be applied initially at a first level sufficient to cause the crimper jaws to close on and grip the terminal but less than sufficient to cause the crimper jaws to crimp the terminal, and subsequently applied at a second, higher level sufficient to crimp the terminal.
