  • Track wheel block
    Patent number: 4550664
    Abstract: A track wheel has an axially extended hollow hub with internally directed gear teeth capable of receiving an outer toothed driving shaft. The hub is supported by roller bearings in a bearing box from which the wheel may not be inadvertently removed once the box halves have been welded together. The sides of the bearing box have bores in appropriate locations which serve to allow the box to be fastened in a variety of configurations to the element to be transported by the track wheel. The side surfaces of the two halves of the bearing box are provided with recesses for flush and precise arrangement of the roller bearings such that the box can be flushly mounted to other elements. The roller bearings are secured within the recesses by means of snap rings which fit into annular slots located on the outer cylindrical surfaces of the hub.

  • Traveling crane with top girders at the end of a bridge girder
    Patent number: 4385562
    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.
