ABSTRACT OF THE DISCLOSURE 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 forma- tion 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 tooperate efficiently on a large variety of support beam sizes and flange width and slope configurations. The trolley wheels are carried by said housing so as to rotate about axes which slope away from and into acute angle inter- sections 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.
