Dedicated thrust units, separate from the drive units, are added on the slopes and are controlled individually by the control system so as to deliver a constant force in order to prevent the carriages (10) experiencing tension at the links (19, 20) as a result of the weight of the items and/or the carriages (10) present on the slopes."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for driving parcel sorters for installations facilities having considerable changes in levels","description":"The present invention concerns a method and system for sorting items comprising movable carriages (10) intended to transport the items, and connected to each other by a link (19), along a track having","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9688477","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
