摘要： A rolling trolley device adapted to ride upon opposite side flanges of a support beam; said trolley device comprising a generally V-shaped load supporting yoke bar of one-piece formation carrying at the opposite legs thereof a pair of generally tubular-shaped trolley wheel support housings; wheel support members extending from said housings at opposite sides of the legs of said bar; and support beam engaging wheels mounted upon said support members; said housings being keyed to said yoke bar legs in positionally adjustable relation thereon to adapt said device to operate efficiently on a large variety of support beam sizes and flange width and slope configurations. The trolley wheels are carried by said housings so as to rotate about axes which slope away from and into acute angle intersections with the planes of the trolley wheel contact/support surfaces; thereby directionally balancing out the thrust load and reaction load forces to provide an improved wheel tracking operation.

摘要： A rolling bearing type traction wheel and hub assembly which is especially adapted to ride upon either flat (i.e. horizontal) or laterally sloping surfaces such as trolley trackways and/or the opposite side flanges of supporting I-beams or the like; the axis of wheel rotation being in any case canted relative to the support surface. The wheel assembly comprises a generally cylindrical shaped inner bearing race/hub member which is fixed to an external support and is encircled by a rotatable outer race/wheel member, with rolling bearings enclosed therebetween. The wheel and hub parts are formed of sheet material and are so shaped as to novelly facilitate initial assembly thereof. When the device is operating under load the parts automatically float into self-aligning operational relationship and are retained in proper operative relationship without need of any auxiliary retention device.
摘要翻译：一种滚动轴承型牵引轮和轮毂组件，其特别适于骑在支撑I型梁等的平坦（即水平）或横向倾斜表面，例如手推车轨道和/或相对的侧边缘; 在任何情况下，车轮旋转的轴线相对于支撑表面倾斜。车轮组件包括大致圆柱形的内部轴承座圈/轮毂构件，其固定到外部支撑件并且被可旋转的外座圈/车轮构件包围，其中包围有滚动轴承。车轮和轮毂部分由片材形成，并且成形为新颖地促进其初始组装。当设备在负载下运行时，零件自动浮动成自对准操作关系，并保持正确的操作关系，无需任何辅助保持装置。
