The OHT apparatus includes a rail module and a differential overhead trolley. The rail module includes a main rail and a first rail, and defines a turning path extending from the main rail to the first rail. The differential overhead trolley is movably disposed on the rail module, and includes a walking mechanism and a carrying body that is hung on the rail module by being connected to the walking mechanism. The walking mechanism includes two differential wheels and a driving unit that is connected to the two differential wheels. When the differential overhead trolley is moved along the turning path, the driving unit is configured to drive the two differential wheels to move along the first rail by different rolling velocities."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Overhead hoist transfer apparatus","description":"An overhead hoist transfer (OHT) apparatus and a differential overhead trolley thereof are provided.
