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.","language":"en","published_at":"2026-09-15T11:32:46.933832Z","canonical_url":"https://opentechnical.org/p/OT-2026-000000031","status":"PUBLIC","supersedes":null,"keywords":["power and free","monorail carrier","pusher dog","overload protection","material handling","disengagement mechanism","carrier accumulation","conveyor system"],"extent":{"words":2780,"paragraphs":19,"figures":3},"hashes":{"canonical_text_sha256":"406527884a8c3126e88544e8dc84aaae5036e43554205c9f627b7fb566f01f39","html_sha256":"dbd257c6edadb3f94e5bee7d511fd50d8c54bdebdfd3f271ec9aee9066288101","pdf_sha256":"5ab551c0c069269cadd4ffc8b23051071f86c23dfb5d167282b818eb6c036d3a","markdown_sha256":"5105ec8f31c2d5afa3ac5fe8acc0ea22a2b2dcabc713d7c8e9aa715e85940556","manifest_sha256":"e8565979171cbe23638788d6ab6cb0477d1dfadb100942ef1518916959eb61ce"},"links":{"html":"https://opentechnical.org/p/OT-2026-000000031","text":"https://opentechnical.org/p/OT-2026-000000031/publication.txt","markdown":"https://opentechnical.org/p/OT-2026-000000031/publication.md","pdf":"https://opentechnical.org/p/OT-2026-000000031/publication.pdf","manifest":"https://opentechnical.org/p/OT-2026-000000031/manifest.json","signature":"https://opentechnical.org/p/OT-2026-000000031/manifest.sig","integrity":"https://opentechnical.org/p/OT-2026-000000031/integrity"},"categories":[{"category_id":"CAT-000000142","path":"conveyors-transport-systems/monorail-and-overhead/power-and-free-systems","name":"Power and Free Systems","primary":true},{"category_id":"CAT-000000125","path":"conveyors-transport-systems","name":"Conveyors & Transport Systems","primary":false},{"category_id":"CAT-000000141","path":"conveyors-transport-systems/monorail-and-overhead","name":"Monorail and Overhead","primary":false},{"category_id":"CAT-000000008","path":"material-handling/conveying-systems/overhead-conveyors","name":"Overhead Conveyors","primary":false}]}
