The direction maintaining module includes a main channel, a first retaining channel and a second retaining channel that are spaced apart from the main channel, a switch channel, and a switching mechanism connected to the switch channel. The switch channel is disposed among the main channel, the first channel, and the second channel. The switching mechanism is configured to drive the switch channel to move between a turning position and a straight position. When the switch channel is at the turning position, the switch channel connects the main channel and the first retaining channel. When the switch channel is at the straight position, the switch channel connects the main channel and the second retaining channel."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Overhead hoist transfer (OHT) apparatus, guiding device of OHT apparatus, and direction maintaining module of OHT apparatus","description":"An overhead hoist transfer (OHT) apparatus, a guiding device of the OHT apparatus, and a direction maintaining module of the OHT apparatus are provided.
