ABSTRACT:
A powered conduit bending tool comprises a portable drive housing including a handle and having a powered drive gear. A bracket is secured to the housing defining a pivot connection spaced from the drive gear. A guide is operatively secured to the housing. A platform is pivotally connected to the bracket at the pivot connection and includes a driven gear operatively engaging the drive gear to controllably pivot the platform. A shoe is removably mountable to the platform and comprises a first bender defining a downwardly opening arcuate channel selectively positionable proximate the guide. A hook is proximate one end of the bender for engaging a conduit received in the channel. In use, the guide supports a conduit engaged by the hook and pivotal movement of the shoe driven by the platform deforms the conduit as it passes by the guide.
