  "abstract": "This disclosure describes a power and free monorail carrier system featuring a pusher dog designed to disengage under controlled overload conditions. The arrangement prevents damage to the carrier or the power chain drive system when a carrier becomes jammed or obstructed. It details the mechanism for disengagement, the method for detecting a disengaged carrier, and the procedures for recovery and re-engagement. The system also addresses accumulation behavior and maintains functionality on inclined sections, offering a protective measure against system overloads in material handling applications.",
