摘要:
An overhead hoist transfer (OHT) apparatus and a differential overhead trolley thereof are provided. 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.

A vehicle operated by electromagnetically connecting the vehicle to a moving magnetic means. The vehicle has a plurality of wheels running on rails and has electromagnetic means thereon. Running in the same direction as the rails is a magnetic means, such as a magnetic belt or chain, and the electromagnetic means on the vehicle is energized to electromagnetically connect the vehicle with the moving magnetic means.
