摘要： A trolley assembly (10) for a conveyor includes a wheel assembly (12) and a trolley arm (14). The wheel assembly (12) includes a wheel (18) that is rotatably mounted to an axle (20), with the axle extending along an axis of rotation of the wheel and comprising a mounting portion that is non-rotatably mounted to or at least partially received in the trolley arm (14). The mounting portion of the axle (20) may be inserted into a passageway (15) and at least partially expanded to limit retraction of the axle from the passageway, or a fastener (16) or other retaining means may secure the axle at least partially within a passageway of the trolley arm. The mounting portion of the axle may comprise a non-cylindrical mounting portion that is received in a non-cylindrical-shaped passageway of the trolley arm.

摘要： A trolley assembly for a conveyor system includes a pair of trolley arms having wheels for rolling engagement with a track or rail of the conveyor system. A trolley attachment is adjustably mounted to the trolley arms and adjusted relative to the trolley arms to adjust a position of the trolley attachment relative to the wheels. The trolley attachment is positionable at a selected one of a plurality of vertical positions relative to the trolley arms and the trolley attachment is retained at the selected one of the plurality of vertical positions by engagement of the trolley attachment with the trolley arms. The engaging elements of the trolley arms or attachment may comprise projections, and the engaging elements of the other of the trolley arms or attachment may comprise recesses, with the recesses receiving the projections when the trolley attachment is positioned between the inner surfaces of the trolley arms.

摘要： A trolley wheel assembly (210) includes a wheel portion (212) rotatably positioned around a hub portion (214) and at least one sliding member (217) positioned between the wheel portion and the hub portion. The sliding member defines a mating surface for mating with a generally correspondingly formed mating surface of the wheel portion and/or the hub portion. The mating surface of the sliding member defines a radial projection (217a) at least substantially circumferentially around the sliding member. The radial projection may slidably mate with the generally correspondingly formed mating surface of the wheel portion and/or the hub portion to facilitate rotation of the wheel portion about the hub portion. The wheel assembly may include one or more inserts (216a, 216b) that define the correspondingly formed mating surface and that are positioned between the sliding member and the wheel or hub portion to facilitate manufacturing and assembly of the wheel assembly.
