Embodiments of the disclosure relate to automated dolly assemblies having loading and unloading racks and traveling along a track secured to a floor. In one embodiment, an automated dolly assembly includes a moveable frame having a mobility mechanism, one or more loading racks, one or more unloading racks, a receiver arm connected to the moveable frame and a moveable pulley connected to the receiver arm. The moveable pulley has weights. The mobility mechanism is coupled to a bottom surface of the moveable frame. The one or more loading racks and the one or more unloading racks are proximate to a top surface of the moveable frame. The receiver arm is rotatably moveable between a horizontal position and a vertical position and configured to engage the automated dolly assembly with an overhead conveyor.

Support frames and rail cars include first and second side drive plates, first and second cross members connecting the respective ends of the side drive plates, third and fourth cross members connecting the side drive plates at a select distance from the first and second cross members, a coupling assembly situated at the first cross member and adapted to connect another rail car thereto, and first and second diagonal support members connected to the first cross member at an angle sufficient to substantially direct forces from the coupling assembly to the third cross member and side drive plates. The support frames and rail cars may be used for conveying bulk materials on a rail transport system.

A work apparatus and a production line that effectively moves a work apparatus at a production line while reducing setup costs. A work apparatus of the production line includes an exchanging device configured to perform collecting and supplying of an exchange element set on each of the multiple electronic component mounters; a first rail provided on a front section of the multiple electronic component mounters, extending in the conveyance direction of the circuit board, and including a planar traveling path; and a moving device configured to move the exchanging device along the first rail by driving a driving wheel configured to engage with the traveling path of the first rail via friction.

Disclosed is an interconnected transportation network system, wherein same is related to the field of transportation facilities and control, and comprises a main transportation system, a transfer system and an entry/exit system. The main transportation system is formed of a closed annular rail vehicle, and the annular train moves continuously on a T-shaped track to fulfil a passenger transportation task by means of multi-point drive. The transfer system (intercommunication) is of the same structure as that of the main transportation system, and the passengers transfer between main transportation lines by means of the transfer system. The entry/exit system (terminal) is formed of an annular buffer vehicle system and a stepping speed control system, and the passengers enter or exit the main transportation lines in a self-service manner by means of the entry/exit system.
