A transport mechanism (28) is disclosed for use in a pipe bender (10) for bending pipe sections (12), particularly pipe sections having a diameter greater than one foot. First and second powered rollers (30, 32) are mounted within the pipe bender and driven by hydraulic motors to move the pipe section in a controlled manner through the pipe bender. A hold down roller (34) is pivoted against the pipe section to force the pipe section into engagement with the powered rollers to insure an adequately frictional engagement between the rollers and the pipe section to move the pipe section through the pipe bender.
