The utility model provides a supporting rope wheel beam support. The supporting rope wheel beam support comprises a supporting rope support structure and a swing prevention device, the swing prevention device is fixedly connected with a beam in the supporting rope support structure, and distance exists between the swing prevention device and a supporting rope wheel in the supporting rope wheel support structure along a beam direction. By arranging the swing prevention device, the supporting rope wheel beam support enables the swing prevention device to obstruct an aerial human transportation trolley in a swing direction and limit the swing of the aerial human transportation trolley when horizontal swing of the aerial human transportation trolley surpasses the stable distance, and therefore swing amplitude of the aerial human transportation trolley is gradually reduced, and is gradually smooth and steady and safety of passengers is guaranteed.
