Features: The Challenger 6-20 Pipe Bender is designed to bend steel pipe of various wall thickness and alloys. It is manufactured with the highest quality products to provide endurance in the most adverse environmental conditions. The bending force is provided through the use of four (4) hy- draulic cylinders, two of which operate the stiffback and two which operate the pin-up. The operator controls are located on the front of the machine above the control stand. It is equipped with a lifting tongue for ease in relocating the ma- chine as the bending process moves down the right-of-way.
