Abstract
A trolley for a conveying system includes a first trolley arm with a trolley wheel rotatably mounted thereon, a second trolley arm with a trolley wheel rotatably mounted thereon, and a load bar. The trolley wheels roll along a track of the conveying system to move the trolleys along the conveyor track. The first trolley arm connects to a first attachment element, which includes a base portion and an attaching member that are integrally formed together. The load bar connects to the second trolley arm and to the attaching member of the first attachment element. The load bar has a slot proximate to one or both ends for receiving the attaching member. The attaching member is retainable in the slot, such as via a retaining pin. The first and second trolley arms are connected together via the load bar.
