  • Patent number: 11925584
    Abstract: A medical suspension bridge includes a cross beam, a suspension pipe and a moving module. The cross beam is connected with the suspension pipe. The moving module is movably connected with the cross beam. The cross beam includes a load-bearing beam. The moving module includes a cable carrier moving plate extending to the upper portion of the load-bearing beam. The medical suspension bridge further includes a cable carrier.

  • Patent number: 11904915
    Abstract: An article transport vehicle that travels along a traveling path is provided with an obstacle sensor that detects an obstacle that exists in a detection area, and a control unit that controls the traveling speed of the article transport vehicle based on detection information of the obstacle sensor. A non-detection area where detection of the obstacle by the obstacle sensor is not performed is set within the detectable area of the obstacle sensor, and a situation in which the non-detection area exists on a detection line that joins a part of the detection area and the obstacle sensor is defined as a specific situation. The control unit, in the specific situation, and a situation where an undetectable area in which it is not possible to detect the obstacle exists in the detection area because a shield exists in the non-detection area, reduces the speed of the article transport vehicle to a second traveling speed slower than the first traveling speed.
