ABSTRACT:
A power assisted system for tensioning and cutting off flexible cable ties includes a handheld unit coupled to a remote power unit by a flexible pull-cable. A trigger on the handheld unit signals the remote power unit to pull the pull-cable and thereby actuate the tool. A tie gripping and tensioning mechanism is provided in the handheld unit as is a cutoff mechanism that automatically cuts off the cable tie tail when the desired tension is achieved. Because operating power is provided by the remote unit, the handheld unit can be made small and lightweight without sacrificing power. Control signals are communicated from the handheld unit to the remote unit through wires carried alongside the pull-cable within a common sheath. Alternatively, the control signals can be communicated through the pull-cable itself.
