A conveying-traveling-body-utilizing conveying device links conveying traveling bodies to each other where load bars are continuous to each other. A linked part is provided at one end of the load bar, and a linking hook is provided at the other end which can engage with and disengage from the linked part. The linking hook is pivotally supported and is vertically movable between a pre-engagement orientation separated upward from the linked part, with respect to an engaged orientation of covering the linked part from above, and a standby orientation tilted to a lowering limit from the engaged orientation by an urging force. When the linking hook is in the standby orientation, longitudinally adjacent conveying traveling bodies can approach each other to a connected state, where the respective load bars are abutted against each other, without the linking hook in the standby orientation and the linked part contacting each other.

A transport system in a fabrication facility includes a driving unit moving along a driving rail, and a steering unit selectively contacting a steering guide rail at a branching part where the driving rail branches off. The steering unit includes horizontal steering wheels contacting a vertical guide part of the steering guide rail, and vertical steering wheels contacting a horizontal guide part of the steering guide rail.

A stabilized carrier basket trolley for a transporter system, the trolley has two cars on the track, on a first side of a support plate and pivotable relative thereto. A distance between the cars changes during traversal of curves and a center of the trolley moves relative to the track towards the inside of a curve. A carrier basket is pivotably connected on the support plate and pivots about a pivot axis. The trolley includes a gear mechanism for actively compensating a moment acting on the carrier basket during traversal of curves that includes a drive wheel drivingly connected to a first gear rotatably mounted on the support plate, and a second gear, meshing with the first gear, non-rotatably connected to the carrier basket. The drive wheel comes into contact with a side of the track upon movement of the center of the trolley relative to the track.

Provided is a conveyor device including a friction roller type driving device for catch-up, a guide unit that supports the friction roller type driving device to be movable along a conveyance direction of a carriage, and a biasing unit that applies a biasing force to the for biasing the friction roller type driving device to bias it in a downstream direction, the friction roller type driving device moving in the upstream direction against the biasing force by a force in the upstream direction acting on the friction roller type driving device when a following carriage separated from a rear end carriage of a conveyance line in the upstream direction catches up with the rear end carriage. The biasing unit includes a spring that is a generation source of the biasing force, and a biasing force adjustment mechanism that adjusts the biasing force and maintains the magnitude of the biasing force substantially constant.
