An overhead transport vehicle performs a first transfer operation of holding an article placed on a loading pedestal of a transport origin, and a second transfer operation of placing the article onto a loading pedestal of a transport destination. A control device causes a shooting device to obtain a first shot image of the upper face of the article placed on the loading pedestal of the transport origin, and adjusts the relative positional relationship between the holding portion and the article placed on the loading pedestal of the transport origin based on the first shot image and first reference image data, and causes the shooting device to obtain a second shot image of the upper face of the loading pedestal of the transport destination, and adjusts the relative positional relationship between the holding portion and the loading pedestal of the transport destination based on the second shot image and second reference image data.

An overhead conveyor system with an elongate box girder (9) having a first inner space with rails (12) and a second elongate inner space comprising an endless driven drive element (5, 6) is provided with at least one carrier (14, 14′) adapted to run on said rails (12) wherein said carrier is provided with an elongated body (C) supporting at least one friction driver (15), wherein said at least one friction driver is in the form of a friction arm assembly (19) with an upper end (20), a lower end (21) and an intermediate portion (22) between said upper and lower ends, said upper end comprising a friction shoe (25) adapted to be pressed upwards by the force of gravity towards engagement with the drive element (5) so as to transfer drive to the carrier.

An adjustable transfer mechanism for a power and free conveyor system includes a free track defining a conveyor path. A first power track defines a first drive path for a first drive member of the first power track to drive a trolley. The first power track is positioned to extend along the conveyor path up to a divergence point where the first power track diverges from the conveyor path. A second power track defines a second drive path for a second drive member of the second power track to drive the trolley. The second power track is positioned to extend along the conveyor path from a convergence point downstream of the divergence point so that the second drive member can pick up the trolley dropped off by the first power track. At least one of the divergence and convergence points is adjustable along the conveyor path.

An article transport facility includes one or more rails which include one or more portions in which a travel path is curved, and an article transport vehicle configured to travel along the one or more rails to transport an article. The article transport vehicle includes a guided portion configured to be in contact with the one or more rails to be guided thereby, an obstacle detection sensor configured to detect an obstacle in a detection area which is set to be located ahead of the article transport vehicle, and a setting portion configured to changeably set the detection area. The setting portion is configured to change the detection area depending on an in-contact-rail shape which is a shape of one or more portions of the one or more rails that the guided portion is in contact with.

A system for supplying power to a trolley chain. The system includes: a trolley chain, consisting of at least two trollies coupled with one another, wherein the trolley chain has a closed bus; and a stationary energy conductor along the track of the trolley chain. The stationary energy conductor consists of one or more successive segments, which are spaced apart from each other. The closed bus has several transmission heads, which are designed to supply the closed bus with electricity from the stationary energy conductor without contacting the stationary energy conductor, if they are within a pre-determined distance to the stationary energy conductor. During a journey of the trolley chain along the track, at each moment in time, at least one of the transmission heads supplies the closed bus with electricity from the stationary energy conductor.

The invention relates to a tire conveyor for a transport device, in particular gondolas, of a cable car installation. The conveyor includes tires, which are arranged along a track, and a drive train for the tires. The drive train has at least one drive pulley, in particular a belt pulley, and at least one drive device, in particular a belt. A guide is arranged along the track, at least in some sections, and at least one measurement device for measuring at least one property of the drive train or a component of the drive train is displaceable on the guide.

A brake assembly for a conveyor system includes a first bracket, a second bracket and a brake member. The first bracket is configured to receive a channel of the conveyor system. The second bracket is spaced from the first bracket and configured to receive the channel of the conveyor system. The brake member is pivotally connected to the second bracket. A pivot axis about which the brake member is configured to pivot is disposed outwardly of the second bracket. A biasing member is configured to bias the brake member inwardly.
