A conveyance system that prevents conveyance carriages from mistakenly entering an area includes a rail extending across a plurality of areas, a FOUP conveyance vehicle that travels along the rail, a conveyance vehicle that has a width and a height at least one of which differs from that of the FOUP conveyance vehicle, an optical sensor that is provided to the FOUP conveyance vehicle, arranged at a position that does not overlap the conveyance vehicle in a traveling direction, and detects an obstacle in front, and a member to be detected that is arranged, in an entry section into a certain area where only the conveyance vehicle is allowed to enter, at a position where the conveyance vehicle is allowed to enter the certain area, the position being detectable by the optical sensor provided to the FOUP conveyance vehicle.

Provided is a transport system to facilitate interlayer movement of a transported object. The transport system comprises: a rail device; and a transport vehicle moving in the rail device, wherein the rail device comprises: a first rail with a first inclination angle; a second rail with a second inclination angle larger than the first inclination angle; a first connection rail configured to connect the first rail to the second rail; and a rack rail installed along the first connection rail and the second rail, wherein the transport vehicle comprises: a frame; a driving wheel connected to the frame and moving the first rail, the first connection rail and the second rail; and a pinion gear connected to the frame and moving along the rack rail.

A storage system prevents a large load from being applied to a part of the ceiling. The storage system in which a rack is provided by being suspended from a first position of a ceiling by a first suspending member attached to a grid ceiling, a second overhead track is provided by being suspended from a second position of the grid ceiling by a second suspending member attached to the grid ceiling, and the first position and the second position are set to be apart by at least a predetermined distance.

An overhead transport system includes a suspended railway and a motorized carrier configured to travel along the suspended railway. The motorized carrier includes a motorized trolley configured to move the motorized carrier along the suspended railway, chassis/beam configured to carry an object below the motorized trolley, and a bumper and deflection system configured to prevent the object from contacting another object.

An overhead transport system includes an overhead transport vehicle including a conveyor and a body, and a controller. The conveyor includes wheels to travel on rails including straight rails and intersection rails alternately arranged with a gap in each of a first direction and a second direction perpendicular to the first direction. The controller is configured or programmed to execute steering control to steer the wheels in a state in which each of the wheels is positioned on one of the intersection rails different from one another. A steering center of the wheel under the steering control is on the intersection rail and inward of the body from a ground contact point of the wheel on the intersection rail.

A ropeway vehicle transportation network includes pairs of ropeway cables on which ropeway vehicles travel the network stations. A plurality of network stations are line changer stations connected to at least two ropeway lines. Each line changer station includes shifter rails that rotate around a vertical axis. When a first ropeway vehicle is on the shifter rails, the shifter rails can be rotated to select on which set of the at least two ropeway lines the first ropeway vehicle will traverse when the first ropeway vehicle exits the shifter rails.

A ropeway vehicle is used within a ropeway vehicle transportation network. The ropeway vehicle includes at least one power drive wheel that is powered to move the ropeway vehicle along ropeway lines. At least one commutator wheel draws electrical power from ropeway cables that form the ropeway lines. A controller includes an on-board battery to back-up and supplement electrical power obtained from the ropeway cables.

The present invention relates generally to ground transportation systems, and more particularly to a fixed guideway transportation system that achieves a superior ratio of benefits per cost, is lower in net present cost and thus more easily justified for lower density corridors, and can provide passenger carrying capacities appropriate for higher density corridors serviced by mass rapid transit systems today.
