ABSTRACT OF THE DISCLOSURE An electric driven portable conduit bender provided with a bending shoe assembly which is rotatably mounted on a vertical axis on the upper end of the bender housing. The bending shoe assembly is provided with a pair of grooved bending shoes which are diametrically disposed, and which are each provided with a different size hook for grasping a conduit and holding it against the bending shoe during a bending operation. A pair of polyurethane support rollers are adjustably mounted on the upper end of the bender housing on a single axis. A conduit to be bent is disposed on a support means on the upper end of the bender housing against the two support rollers and it is grasped by one of the bending hooks. A dynamically braked permanent magnet motor is employed to rotate the bending shoe assembly through a bending cycle and then though a reversed unload cycle during which the hook, which is provided with a cammed surface, rides up over and on top of the bent conduit to permit the bent conduit to be quickly and easily removed from the bending apparatus. An external dial indicator is provided for adjusting an internal adjustable cam means for controlling the degree of bend to be imparted on a conduit. -2-
