Claims

[Scope of Claim for Utility Model Registration] (1) A drive device that can be connected to and separated from a work cart that is suspended from a guide rail laid along the longitudinal direction of a bridge girder and that is attached to a cradle. A pair of left and right trolley frames are supported on the supporting shafts so as to be swingable and slidable toward or away from each other, and running wheels are respectively supported on the pair of left and right trolley frames. The left and right running wheels can be engaged with and disengaged from the guide rail by sliding the frames toward each other or away from each other, and when the running wheels are engaged with the guide rail, the cradle can swing freely about the support shaft. A drive wheel to be in contact with the lower surface of the guide rail is installed on one end of the cradle in a positional relationship that allows for suspension, and a drive means to rotate the drive wheel is installed. A traveling drive device for a working trolley for a bridge or the like, comprising: a roller that presses the lower surface of the guide rail so as to bring the drive wheel into pressure contact with the lower surface of the guide rail, the roller being movable up and down on the other end of the support shaft; (2) A pair of left and right trolley frames are swingably and interchangeably mounted on a work platform that is movably suspended from guide rails laid along the longitudinal direction of the bridge girder. The pair of left and right trolley frames are slidably supported in the direction toward or away from each other, and the running wheels are respectively pivotally supported by the pair of left and right trolley frames.By sliding the pair of trolley frames toward or away from each other, the left and right running wheels are moved toward or away from the guide rail. The support shaft of the support is placed in a positional relationship that allows the support to be swingably suspended about the support shaft when the running wheel is engaged with the guide rail. A drive wheel to be brought into contact with the lower surface of the guide rail is installed at one end as a boundary, and a drive means to rotate the drive wheel is provided,
A traveling drive device for a work trolley, comprising a roller that is movable up and down and that presses the lower surface of the guide rail so that the drive wheel presses against the lower surface of the guide rail, on the other end of the support shaft; A traveling working trolley for bridges, etc., in which a generator for the equipment and the following are each installed so that they can be connected to and separated from the working trolley and are movable on the working trolley.
