Abstract
The disclosure is directed to the construction of a traveling overhead crane, to enable a desired high degree of precision to be maintained in the attachment of wheel-carrying top girders to the opposite ends of a movable bridge girder. The bridge girder is provided with end plates, to which the respective wheel-carrying top girders are bolted. The end plates are formed with machined annular recesses, surrounding the bolt holes through which the top girders are attached. These machined recesses are so formed that the bottoms thereof constitute a common reference plane. Tubular sleeves of known axial dimension, are received in these recesses and serve to accurately locate the top girders with respect to the predetermined reference plane. The tubular sleeves may in some cases be very short, in the nature of thick washers, for example, or they may be elongated tubes extending through and welded to the top girders. Improved and simplified arrangements are also provided for mounting of the wheels in the top girders.
