ABSTRACT:
A load handling device is disclosed having an improved swing drive assembly including a pivotally mounted swing drive pinion biased against a segmented ring gear by an actuator with a guide roller adjacent the pinion engaging a guide flange concentric with the ring gear to limit the maximum tooth engagement between the pinion and ring gear and thereby provide essentially constant backlash on the pinion gear regardless of eccentricities or other irregularities in the ring gear.
